When people think about online misogyny, they probably envision forums and video game chat rooms filled with young men using lewd language, promoting sexist stereotypes and longing for the good old days when women “knew” their place. Arguably the most popular anti-feminist content today, though, is produced by women: tradwives.

The term “tradwife” is an abbreviation of “traditional wife” – often portrayed on these platforms as a white, married, stay-at-home mother. Since the mid-2000s, tradwives have developed a substantial online presence and following, introducing their lifestyle and views to masses of women.

Many viewers are introduced to tradwife content through videos on cooking or decorating – posts that could appeal to a wide audience. But at the core of the tradwives movement are more divisive beliefs: that women are meant to “submit” to their husband’s leadership, for example, or are not meant to work outside the home.

We define misogyny as hatred, prejudice or hostility directed toward women as a group. Many tradwives argue that their lifestyle empowers women to fulfill their true role. Yet some content in the tradwife landscape is indeed rooted in misogynistic beliefs that women are, in some ways, less capable than men. And much more “trad” content is directly opposed to feminist ideas, such the importance of women’s economic independence and sexual freedom.

A growing number of academics and news reports have highlighted tradwives’ growing cultural influence. There’s been less attention, however, on one of the most prominent features distinguishing them from other misogynist online movements: the role of religious beliefs.

As researchers of extremism, we have been working on a new book about the contemporary landscape of misogyny, examining movements such as “incels” and “men’s rights” activists, as well as chauvinist far-right groups such as the Proud Boys.

As part of our research, we analyzed hundreds of tradwife social media posts, videos and blogs. We assert that tradwife culture is not just aiming to restore “traditional” gender roles. It is also an important force in formulating a new model of womanhood: one that incorporates strong religious identity, a specific feminine aesthetic, and far-right ideas.

Filtered femininity

Tradwives create content that fuses what they call “traditional” and “feminine” lifestyles. Specifically, they tend to emphasize the importance of a wife’s submissiveness to her husband, immersion in conservative Christian values, and support for causes such as anti-abortion advocacy. Yet “tradwife’ content spans a broad spectrum: Some influencers focus on relatively apolitical topics like baking and parenting, while others combine those with more ideologically charged content.

In addition, tradwives stress self-sufficient homemaking skills, such as eating homemade and unprocessed food. At times, that emphasis on “wholesomeness” or living “naturally” includes skepticism about mainstream health care, as well as touting “naturopathic” or alternative medicine.

One of the main reasons so many viewers are attracted to the tradlife content is their nostalgic and calming aesthetic, including a focus on cottage-core content: quaint scenes that evoke life on the prairie, capitalizing on viewers’ nostalgia and desire for escapism.

This type of soft-living content is inviting and relaxing. Loose wavy hair, fresh homemade cooking and a farmhouse aesthetic bring to mind “Little House on the Prairie” and help viewers forget the crises of the world outside. We can’t help but feel like we are in the influencer’s kitchen, smelling freshly baked bread and hearing the laughter of children frolicking about.

Yet nothing about tradlife content is effortless. The filters and glamour of Instagram never reflect the hours influencers spend setting up their homes, testing recipes, buying filming equipment and fixing up their appearance for these videos, as shown in countless “get ready with me” videos.

Nevertheless, tradwives often glorify the idea of women’s helplessness,. Some encourage women to focus on what tradwives call “pink jobs,” such as homemaking or child-rearing tasks, not physically demanding “blue jobs,” such as house repairs or extensive landscaping.

In tradwives’ narrative, women aren’t “wired” or “made” to be in the workforce or to be the breadwinner. It is not only too demanding, some of these influencers argue, but actually against nature and God’s intentions to try to “have it all.”

Faith and submission

Most tradwife influencers who talk about faith are Christians of one denomination or another, including Catholics and members of the Church of Jesus Christ of Latter-Day Saints. During analysis for our forthcoming book, we analyzed language in a sample of 23 videos from the seven most popular influencers and found that “God” was the fourth-most popular term – following “women,” “life” and “husband.”

For many influencers, religious piety is a crucial component of their views on gender and convincing viewers to embrace them – particularly their belief that a wife’s fundamental role is to let God and her husband lead the way. Thus, while they don’t necessarily see men and women as unequal, they believe men and women have different roles and different abilities.

Insisting that God is on their side also enhances influencers’ sense of community with their followers, making some platforms almost seem like a parish. They will emphasize specific biblical verses supporting the norms they advocate – such as Titus 2:5, which they interpret as advising women to stay at home; and Genesis 1:28, in which God commands humans to “be fruitful, and multiply.”

“Womanhood is not a man-made idea constructed from ancient traditions and cultural trends,” the sisters behind the YouTube channel “Girl Defined” write in their book, “Made to be She: Reclaiming God’s Plan for Fearless Femininity.” “It’s a God-designed reality that He established from the beginning of time.”

Political voice

Some tradwife influencers focus on household management and religious content, while others are bolder in their political commentary – from simple TikToks to hours of live-streamed podcasts with guest speakers discussing hot-button issues. One frequent theme is opposition to abortion, especially since the overturning of Roe v. Wade in 2022.

The LGBTQ+ rights debate and related questions about how to define a woman have also become a focus for many tradwives, who argue only God can assign gender, and that it is synonymous with biological sex.

In some cases, tradwives’ advocacy extends to white nationalism and nativism. For example, some tradwives will justify the virtue of a large family by alluding to the importance of maintaining a white, Christian majority in the United States.

Modern anxiety

Much of tradwives’ messaging revolves around cultural flash points, problems that underscore anxiety about modern womanhood: challenges in forming stable relationships, providing nutritious meals, and building a career while trying to raise a family. One popular video on the Girls Defined channel, less than a minute long, warns viewers about birth control, Planned Parenthood, feminism and mood stabilizers. “Women, through all the years of feminism, through all the years of freedom, women are more depressed, more anxious, hurting more than ever,” one of the sisters says, “and what we are being told to do is not working.”

These challenges are presented as inevitable consequences of abandoning divinely ordained feminine roles – positioning religious tradwives’ messages as not merely personal opinions, but sacred truths. Any effort to counter misogynist messaging on these platforms, we argue, cannot just rely on facts, but exposing followers to other visions of what it means to be a religious woman.

It is a sad fact of online life that users search for information about suicide. In the earliest days of the internet, bulletin boards featured suicide discussion groups. To this day, Google hosts archives of these groups, as do other services.

Google and others can host and display this content under the protective cloak of U.S. immunity from liability for the dangerous advice third parties might give about suicide. That’s because the speech is the third party’s, not Google’s.

But what if ChatGPT, informed by the very same online suicide materials, gives you suicide advice in a chatbot conversation? I’m a technology law scholar and a former lawyer and engineering director at Google, and I see AI chatbots shifting Big Tech’s position in the legal landscape. Families of suicide victims are testing out chatbot liability arguments in court right now, with some early successes.

Who is responsible when a chatbot speaks?

When people search for information online, whether about suicide, music or recipes, search engines show results from websites, and websites host information from authors of content. This chain, search to web host to user speech, continued as the dominant way people got their questions answered until very recently.

This pipeline was roughly the model of internet activity when Congress passed the Communications Decency Act in 1996. Section 230 of the act created immunity for the first two links in the chain, search and web hosts, from the user speech they show. Only the last link in the chain, the user, faced liability for their speech.

Chatbots collapse these old distinctions. Now, ChatGPT and similar bots can search, collect website information and speak out the results – literally, in the case of humanlike voice bots. In some instances, the bot will show its work like a search engine would, noting the website that is the source of its great recipe for miso chicken.

When chatbots appear to be just a friendlier form of good old search engines, their companies can make plausible arguments that the old immunity regime applies. Chatbots can be the old search-web-speaker model in a new wrapper.

But in other instances, it acts like a trusted friend, asking you about your day and offering help with your emotional needs. Search engines under the old model did not act as life guides. Chatbots are often used this way. Users often do not even want the bot to show its hand with web links. Throwing in citations while ChatGPT tells you to have a great day would be, well, awkward.

The more that modern chatbots depart from the old structures of the web, the further away they move from the immunity the old web players have long enjoyed. When a chatbot acts as your personal confidant, pulling from its virtual brain ideas on how it might help you achieve your stated goals, it is not a stretch to treat it as the responsible speaker for the information it provides.

Courts are responding in kind, particularly when the bot’s vast, helpful brain is directed toward aiding your desire to learn about suicide.

Chatbot suicide cases

Current lawsuits involving chatbots and suicide victims show that the door of liability is opening for ChatGPT and other bots. A case involving Google’s Character.AI bots is a prime example.

Character.AI allows users to chat with characters created by users, from anime figures to a prototypical grandmother. Users could even have virtual phone calls with some characters, talking to a supportive virtual nanna as if it were their own. In one case in Florida, a character in the “Game of Thrones” Daenerys Targaryen persona allegedly asked the young victim to “come home” to the bot in heaven before the teen shot himself. The family of the victim sued Google.

The family of the victim did not frame Google’s role in traditional technology terms. Rather than describing Google’s liability in the context of websites or search functions, the plaintiff framed Google’s liability in terms of products and manufacturing akin to a defective parts maker. The district court gave this framing credence despite Google’s vehement argument that it is merely an internet service, and thus the old internet rules should apply.

The court also rejected arguments that the bot’s statements were protected First Amendment speech that users have a right to hear.

Though the case is ongoing, Google failed to get the quick dismissal that tech platforms have long counted on under the old rules. Now, there is a follow-on suit for a different Character.AI bot in Colorado, and ChatGPT faces a case in San Francisco, all with product and manufacture framings like the Florida case.

Hurdles for plaintiffs to overcome

Though the door to liability for chatbot providers is now open, other issues could keep families of victims from recovering any damages from the bot providers. Even if ChatGPT and its competitors are not immune from lawsuits and courts buy into the product liability system for chatbots, lack of immunity does not equal victory for plaintiffs.

Product liability cases require the plaintiff to show that the defendant caused the harm at issue. This is particularly difficult in suicide cases, as courts tend to find that, regardless of what came before, the only person responsible for suicide is the victim. Whether it’s an angry argument with a significant other leading to a cry of “why don’t you just kill yourself,” or a gun design making self-harm easier, courts tend to find that only the victim is to blame for their own death, not the people and devices the victim interacted with along the way.

But without the protection of immunity that digital platforms have enjoyed for decades, tech defendants face much higher costs to get the same victory they used to receive automatically. In the end, the story of the chatbot suicide cases may be more settlements on secret, but lucrative, terms to the victims’ families.

Meanwhile, bot providers are likely to place more content warnings and trigger bot shutdowns more readily when users enter territory that the bot is set to consider dangerous. The result could be a safer, but less dynamic and useful, world of bot “products.”

I worked for Google for 16 years, and thus received compensation from them to protect against external liability.

You might imagine nuclear power plants as behemoth facilities spanning hundreds of acres. Nuclear microreactors, by contrast, could sit on land the size of a football field and power a whole town.

However, after decades of fraught relationships between the nuclear industry and communities in many parts of the U.S., building these tiny reactors requires reckoning with the complex history of nuclear technology and rebuilding public trust.

Microreactor technology for use in towns or cities hasn’t been developed yet, but many researchers have been building the case for its use.

For example, this technology could benefit college campuses, remote communities in Alaska primarily powered by oil and diesel, tech companies looking for reliable electricity for AI data centers, companies in need of high-temperature heat for manufacturing and industrial processes, mining operations that need a clean energy source and even military bases in search of a secure source of energy.

I’m a nuclear engineer who has been exploring nuclear microreactors’ potential. My research and teaching focuses on some of the questions that would come with placing miniature nuclear reactors close to where people live.

Microreactors: A history

Nuclear microreactors as a technology are both new and old. In the 1940s and ’50s, the American military and government began developing small reactors and nuclear batteries to power submarines and spacecraft.

After developing these small-scale reactors and batteries for various missions, the nuclear industry’s focus shifted to power reactors. They began to rapidly scale up their designs from producing tens of megawatts to the gigawatt-scale systems common around the world today.

These historical reactors were small because scientists were still learning about the physics and engineering underlying these systems. Today, engineers are deliberately designing microreactors to be small.

Microreactors aren’t to be confused with small modular reactors – these are often scaled-down, modularized versions of large reactors. Small, modular reactors can be built as single units or in clusters to achieve the same capacity as a full-size reactor. Microreactors would be smaller than these, with a power capacity under 20 megawatts.

Manufacturing and cost

Because they’re small, microreactors wouldn’t require a massive, multiyear construction project like large nuclear power reactors. Several units could be assembled in a factory each year and shipped off to their final destinations in a truck or on a barge.

Large reactors are not inherently flawed – in many ways, they remain the more economic nuclear energy option. However, electric utility companies have recently hesitated to invest in large reactors because of the multibillion-dollar nature of these projects.

Microreactors require a different but equally significant kind of investment. Though individual units will have a significantly lower price tag, building a factory to produce these microreactors is a massive undertaking. Reactor companies are waiting for their order books to fill up before investing in factories.

It’s a catch-22. Without orders, technology developers are unlikely to build microreactor factories. And future users of these new reactors are unlikely to place orders until this new style of production has been tested and the initial units built.

Future users are also waiting to see what the microreactors will actually cost. Reactor developers have put forward many cost estimates, but in the past, estimates for nuclear reactors haven’t always been reliable. Developers likely won’t know the true numbers until the reactors are actually built.

Initial “first of a kind” units will undoubtedly cost significantly more than later units. As manufacturers learn the best production processes, they’ll be able to make more reactors for less.

In this paradoxical situation in which developers are waiting for orders and users are waiting to see the economics of initial reactors, government funding for building demonstration projects could help usher microreactor technology from early designs to the market.

First movers such as national laboratories, universities, data centers and military bases that are willing to buy these initial reactors also have a role to play in validating the economic feasibility of these new reactors.

Today’s microreactors

In a nuclear reactor, the combination of nuclear fuel and coolant – which is the substance used to both cool the fuel and transport the heat generated by it – used in its design determines what situations it will work best in. Many nonwater coolants can allow reactors to operate at lower pressures, which is a little more safe.

The microreactors being developed today are based on a wide range of reactor technologies and make use of many different combinations of nuclear fuels and coolants.

Some reactors, such as the submarine propulsion reactors, are small, pressurized water reactors – the same basic technology used in most large-scale nuclear power plants. Others use configurations that resemble the small reactors in spacecraft. Still others make use of nuclear fuel and coolant combinations previously attempted in much larger reactors, such as high-temperature gas reactors, sodium fast reactors and even molten salt reactors.

Though encompassing a range of technologies, microreactors are all significantly simpler than the large reactors in use today. In many cases, they have few to no moving parts.

Microreactors, by virtue of being significantly simpler, are going to be more knowable. Because they’re easier to study and understand, simpler reactor systems have fewer points of failure and safety concerns.

Complex systems, such as the large nuclear power reactors, can be fundamentally unknowable, with unexpected entanglements of “unknown unknowns” creating instabilities, safety concerns and potential for failure. Large reactors operate safely today because we have learned about these unknown unknowns over decades of operation. Microreactors, because of their simplicity, will fundamentally be safer and more predictable than the large reactors were when they were first built.

Siting microreactors

Although the Department of Energy oversees microreactor demonstration projects, commercial deployment of microreactors requires approval from the U.S. Nuclear Regulatory Commission, which could take several years and may ultimately determine how soon commercial reactors can be built. Several designs are now approaching or in the early stages of review.

To keep people safe, large reactors have designated emergency planning zones – usually 10 and 50 miles around – which require different degrees of planning and protection to enter. The 10-mile zone has specific shelters and evacuation plans in place, while people in the 50-mile zone may need to take precautions about what they eat and drink in the event of a catastrophic accident but will not need to evacuate.

Because microreactors are smaller and simpler, developers and regulators may significantly reduce their emergency planning zones. The zones could extend only to the facility’s site boundary, or perhaps a few hundred meters beyond it.

A reduced emergency planning zone could mean that microreactors could be built in towns and cities, or embedded in remote communities. They might one day become as ubiquitous as the solar panels and windmills you see when driving through the countryside. And like the submarine reactors that can power a small underwater community of 100, one microreactor could power a rural town.

But even if siting a nuclear microreactor near a town is technically feasible, would the community accept it?

Public engagement

My lab’s ongoing research suggests that the answer to this question is contingent on how technology developers engage with the communities that may host a microreactor. If they attempt to unilaterally decide, announce and defend their decision to build a microreactor without input, communities will likely push back.

However, if developers work with communities to understand their hopes, concerns and priorities, they will likely find that many people are receptive to hyperlocal nuclear energy facilities.

My team’s initial findings suggest that there isn’t a one-size-fits-all approach for designing these facilities. Each community will have its own set of preferences that developers will need to navigate alongside the engineering questions.

In our discussions with community members in southeast Michigan, my research team has seen interest in designing these small energy facilities as a feature of the community that’s easily accessible to local residents. Community members designing hypothetical microreactor facilities with us have proposed shared spaces, recreational facilities, onsite visitor centers or science museums, and public art projects. Instead of hiding these facilities out of sight, they want these places to be inviting and beautiful.

Parents of young children probably recognize the hectic mornings filled with reminding the kids to eat breakfast, brush their teeth and put on their shoes – and hurry up, you’re gonna be late!

Most little kids can’t manage these morning routines on their own because they lack the necessary executive function: the set of skills that affect how people make purposeful decisions that align with their goals. It’s these skills that allow you to set and pursue short-term goals, such as making breakfast, and long-term goals, such as pursuing a successful career.

Early childhood marks a period of significant development in executive function ability. Research shows that children with better executive function tend to grow up to be financially stable, healthy and productive adults. For this reason, many psychologists and educators are seeking ways to help kids develop these skills in early childhood, potentially setting them up for later success.

As important as these skills are, though, attempts to understand where they come from and how to train them have been mostly unsuccessful – until now.

We are psychologists at the University of Tennessee in the Attention, Brain and Cognition Lab, and our recent study provides new insights into how executive function develops.

Where previous attempts failed

There have been many attempts to teach children executive function, in hopes that improvements will translate to other cognitive skills. But these have largely been unsuccessful for two reasons.

First, while children in these experiments learned specific tasks, they didn’t learn skills that would translate to the real world. It’s like how studying for your ACT may make you better at taking the ACT but not necessarily better at the skills you need for your future job.

Second, on the more technical side, measuring brain activity in young children is notoriously difficult. MRIs are too restrictive – not to mention scary – to be used on children while they perform tasks.

New tools offer new insights

Many researchers now use a more child-friendly neuroimaging machine called functional near-infrared spectroscopy, which involves placing sensors on a child’s head – typically in the form of a lightweight cap – to track their brain function. This laser system monitors blood flow in the outer layer of the brain, known as the cortical surface. Blood flow indicates neural activity and reveals areas of the brain that are most busy.

This technology is a step in the right direction, but it’s still difficult to ensure that the sensors are placed in exactly the same way from one session to the next, and from one kid to the next. This challenge is particularly pronounced in longitudinal studies, because children’s heads grow over time.

To solve this problem, our team developed 3D-image reconstruction techniques that allow us to keep track of where brain activation is happening. With the 3D model, we are able to map and measure each child’s individual brain regions.

Our advanced analysis tools allowed us to collect multiple recordings from the same children over several years, confident the sensors were in the correct, consistent spots on their heads for each study phase.

By administering a wide range of tasks that tap into different aspects of neurocognitive function, we were able to pinpoint which regions of a child’s brain are active as they develop executive function skills.

Understanding the nature of executive function

One important aspect of executive function is the ability to filter what information is relevant for completing your goals. Based on previous executive function studies and our mathematical model of the brain’s connections, our team believes that the key is the process of what we call learning labels – that is, learning to name and sort the objects in your environment based on various categories they fit into.

Label learning allows you to move through your world finding tools you need to accomplish your goals and flexible uses for the objects around you. For instance, understanding the labels “smooth” and “concave” would help you identify a spoon. Knowing how the features of a spoon relate to other objects or processes such as “mixing,” “shoveling” or “slinging” can encourage flexible uses of the spoon, so that you recognize you can use the spoon to stir your chocolate milk, eat your cereal or even catapult a bit of breakfast onto your sibling.

So all that learning in a child’s early years of fundamentals such as color, shape and basic sounds and words is preparing them for a life where they can identify what they need to set and meet their goals, small and large.

Further, understanding how to identify and label items in your environment can help you be flexible and notice different aspects of an object when your goals change. For example, if there’s no cow’s milk available, but you know almond milk falls into the same category, you can use it as a substitute. In this way, learning labels for categories of objects lets you identify and act on goal-relevant information around you.

What we found

Using our near-infrared spectroscopy tools, we examined the brain function of 20 children during a series of tasks. We first assessed their label understanding at age 2½ by asking them simple questions about objects, such as, “Which one is red?” or “What color is this one?”

Two years later, when the children were 4½, we brought them back to the lab for an executive function task. First, they would play a few rounds of a shape-sorting game. Then the research assistant would ask them to switch to sorting the same objects by color. This task requires thinking flexibly about the objects and making different decisions about them when the rules change.

We found that brain activity differed before versus after children learned to categorize objects by shape and color. In addition, we found that children who showed stronger activation in their brain’s frontal cortex region during the simpler color and shape labeling tasks at age 2½ performed better on the complex task at 4½. We think this indicates that those children at 2½ were further along in the developmental trajectory of learning categories for objects around them, and thus had richer neurocognitive resources available at 4½ when performing the complex executive function task.

Our findings suggest that label learning extends beyond language and affects how kids can control and regulate their behavior. That is, by having ways of labeling different aspects of objects or the environment, children have ways to cognitively focus on that information in order to guide their behavior.

What’s next?

Our results open the door to finding ways to teach children executive function skills. Scientists can now try to create interventions focused on label learning and grouping objects based on their physical characteristics. Training would likely build on the sort of learning that naturally occurs during play time with caregivers, as well as via children’s books and edutainment videos.

Our team has already begun the next step in this work, examining how to facilitate these learning processes. Our goal is to develop interventions aimed at improving executive function skills in early childhood that will improve broad development outcomes as kids get older.

Source: The Conversation – USA (3) – By William Cornwell, Associate Professor of Cardiology, University of Colorado Anschutz Medical Campus

Nearly half of all Americans have high blood pressure – a condition called hypertension.

Hypertension is the No. 1 risk factor for heart disease and stroke. In addition, hypertension increases risk of dementia and cognitive decline. Heart disease, stroke and dementia are the first-, fourth- and sixth-leading causes of death in the U.S. Unfortunately, only 1 in 4 people with a history of high blood pressure have this condition under control.

In August 2025, the American Heart Association and the American College of Cardiology released new guidelines on prevention and management of hypertension, based on a comprehensive analysis of literature published over the past 10 years.

The Conversation U.S. asked cardiologist Dr. William Cornwell of the University of Colorado Anschutz Medical Campus to explain what the new guidelines mean and how you can work with your doctor to manage your blood pressure.

What are the primary takeaways of the new guidelines?

The most recent guidelines prior to this new statement were in 2017. Since that time, the medical community has learned a lot about hypertension and the best way to control it. The new guidelines provide a great deal of new information.

First, the definition of hypertension has changed. The criteria are more strict, and the target blood pressures are lower than in the past.

The criteria depend on the values of the “systolic” and the “diastolic” pressure. Systolic blood pressure, the top number, represents the pressure in the blood vessels when the heart is squeezing blood into the body. Diastolic blood pressure, the bottom number, is the pressure in the blood vessels when the heart is relaxing. Both numbers are important when determining the severity of hypertension and how it is most appropriately managed.

The new guidelines have removed the category of “prehypertension,” which was defined by a systolic pressure of 120-139 millimeters of mercury (mm Hg), or a diastolic pressure of 80-99 mm Hg. Now, patients are categorized as having “elevated blood pressure” if their blood pressure is 120-129 over less than 80 mm Hg, or stage 1 hypertension if they are 130-139/80-89.

A reading of 140/90 or more is considered stage 2 hypertension, and a reading of 180/120 or greater is a hypertensive crisis. In essence, the bar has been lowered, and this change may impact millions of Americans.

People need to ask their doctors if they have hypertension based on these new criteria and whether or not they should be treated. It is also very important for patients to get advice from their doctors about lifestyle habits that they can incorporate into their daily routine, like diet, exercise and healthy sleep habits to help lower blood pressure.

In addition, the guidelines encourage providers to use a risk calculator, called PREVENT – short for Predicting Risk of Cardiovascular Disease EVENTS – to determine a patient’s overall risk of cardiovascular disease and heart failure. This tool represents a significant advance in personalizing medical care, since it incorporates risk factors unique to the individual, allowing for a tailored approach to medical care.

What is the link between alcohol intake and high blood pressure?

The guidelines encourage people to limit alcohol intake because alcohol increases blood pressure.

A 2023 meta-analysis of seven studies with nearly 20,000 people showed that systolic blood pressure will increase by about 1mmHg for every 10 grams of alcohol consumed. A standard beer contains about 14 grams of alcohol, so regular alcohol consumption may increase blood pressure by several points over time. For people who have been drinking an excessive amount of alcohol but stop, their blood pressure may come back down.

That might not sound like much, but when combined with other unhealthy and risky behaviors, like sedentary behavior, excessive weight, inadequate sleep, psychological stress and smoking, the risk factors start to add up quickly. Together, they can very quickly increase the risk of heart disease, stroke and dementia.

The new guidelines encourage patients to reduce or eliminate alcohol consumption entirely compared with the old guidelines. For people who do want to drink alcohol, the new guidelines recommend that men should drink no more than two drinks per day, and women should drink no more than one drink per day.

What other lifestyle factors did the new report focus on?

The new guidelines also emphasize the fact that diet can have a major impact on blood pressure. They recommend that all adults – with or without hypertension – consume less than 2,300 milligrams of salt, or approximately 1 teaspoon, per day, and more ideally, less than 1,500 milligrams per day. For a comparison, the average American eats more than 3,300 milligrams of salt per day. Patients may also consider potassium-based salt substitutes to further lower blood pressure.

The guidelines recommend a specific diet called the DASH diet, short for Dietary Approaches to Stop Hypertension, for patients with or without hypertension to prevent or treat elevated blood pressure. The DASH diet emphasizes fruits, vegetables, low-fat or nonfat dairy and whole grains. This diet may lead to a reduction in blood pressure by up about 10 mm Hg.

The guidelines also emphasize the need to increase physical activity. On average, for every additional 30 minutes of aerobic exercise a person gets per week, systolic blood pressure decreases by 2 mm Hg and diastolic blood pressure drops by 1 mm Hg, with the largest reduction occurring at 150 minutes of dynamic exercise per week.

Regular exercise also helps you live longer and reduces the risk of cardiovascular disease, stroke and dementia.

What are the main preventive strategies in the report?

The PREVENT risk calculator that the new guidelines recommend incorporates several factors, including demographics, cholesterol levels, medical history and blood pressure, to determine risk. This risk calculator is free and available online to the general public. The PREVENT calculator may be a helpful tool for all Americans since it reliably provides patients and providers with an assessment of overall risk assessment. But it is particularly helpful for people with multiple chronic conditions, like hypertension, high cholesterol, overweight/obesity or diabetes.

The American Heart Association recommends eight essential health behaviors for controlling blood pressure and reducing risk of cardiovascular disease overall. These include healthy diet, regular exercise, stopping or avoiding smoking, sleeping seven to nine hours per night, and controlling weight, cholesterol, blood sugar and blood pressure.

Will the new guidelines change how doctors address high blood pressure?

One of the greatest advances with these new guidelines is the personalized approach to medical care through the use of the PREVENT calculator.

The guidelines recommend that doctors encourage their patients to check blood pressure at home to better understand the fluctuations in pressure that occur throughout the day.

Finally, the guidelines encourage physicians to be more aggressive about treating blood pressure. This may be an important change since uncontrolled blood pressure is a major risk factor for eventual development of heart disease and stroke.

Pennsylvania is due to receive US$2.2 billion dollars from the national opioid settlements, and a new database shows the public where that money is going.

Starting in 2021, a national, bipartisan coalition of attorneys general, including now-Pennsylvania Gov. Josh Shapiro, reached settlements with opioid manufacturers and distributors who had directly contributed to the opioid addiction crisis.

That year, over 5,000 Pennsylvanians died from unintended drug overdoses. That number has since dropped, falling to about 3,300 in 2024.

The opioid settlement payments, which began in 2022 and are slated to continue until 2038, are supposed to fund opioid overdose prevention, treatment, harm reduction, recovery support and other programs. This includes a broad array of interventions in Pennsylvania, from first-responder training for law enforcement to handle people who have overdosed to stigma reduction education and support for medication-assisted treatment, to name just a few.

We are researchers from Penn State University, Temple University and the University of Pittsburgh who helped build a website, which launched in August 2025, that publishes and tracks opioid settlement fund spending data in Pennsylvania.

We are partnering with the Pennsylvania Opioid Misuse and Addiction Abatement Trust, the County Commissioners Association of Pennsylvania and the Pennsylvania Career Development Association. Our team receives funding through the Pennsylvania Opioid Misuse and Addiction Abatement Trust to help the trust with data collection, analysis and web design. However, our website is separate and independent from the trust.

Here are five things we believe Pennsylvania residents ought to know about the spending data, and how it can be used to improve public health:

1. Counties are in the driver’s seat

Out of the 48 states that have received settlements so far, Pennsylvania is one of nine states that have given majority control of settlement spending to local governments.

In Pennsylvania’s case, 70% of the funding goes to counties. Cities and other organizations that were involved in the lawsuits, such as county district attorney offices, get 15%. The remaining 15% goes to the state.

This means that in Pennsylvania, it is mostly up to counties to determine how to best spend the US$2.2 billion. Counties must interact directly with their communities through requests for proposals to distribute funds. They will face critical decisions about how to invest the funds in ways that move beyond pilot programs to sustainable, system-level change.

Requirements from the opioid settlement to spend at least 85% of the money on opioid abatement aim to avoid pitfalls of the 1990s tobacco settlement, when funds were often diverted to general budgets and spent on programs unrelated to getting people to quit smoking.

States that have not given majority control of settlement spending to local governments have created a variety of ways to spend the money. These include a mix of state and local disbursement, as well as special fund-governing bodies charged with deciding how settlement funds are distributed. In some states, the state is the primary decision-maker about how settlement funds are used.

The requirement in Pennsylvania that opioid settlement funds are primarily sent to counties creates an opportunity for local innovation. It will also, eventually, allow experts to evaluate the effectiveness of this local control of funds compared with state control or other structures.

2. Website improves transparency and accountability

When members of the public can see where the money is going, they can hold systems accountable for using the funds effectively. County leaders, meanwhile, can see what programs are currently being funded in other counties that they may want to replicate or scale up.

3. Spending is a marathon, not a sprint

Settlement dollars are just beginning to be distributed and spent. According to the tracker, over $80 million had been spent on approved opioid remediation programs as of Dec. 31, 2024. Settlement payments will continue over the next seven to 18 years, varying by company.

This is a marathon and not a sprint, so communities and decision-makers will have to balance spending that produces short- and longer-term objectives.

Additionally, not all counties are receiving the same amount of money, and that affects what they can do with it.

4. New challenges will arise in opioid crisis

Emerging issues in the opioid crisis will continue to evolve, such as how contaminants like the animal tranquilizers xylazine and medetomidine, or products derived from kratom, a tropical tree, have entered the street drug supply in recent years.

Systematically tracking data will help expand our knowledge base of all programs in Pennsylvania that aim to address the opioid crisis. Some of these programs are based on strong existing evidence, while others will help to build new evidence, especially considering the ever-changing landscape of the crisis.

5. Funding gaps will remain

Opioid settlement funds are an important opportunity to address the opioid crisis, but will not on their own cover all funding gaps needed to address the crisis or the broader public health crises that are its major drivers. These include food and housing insecurity, unemployment, lack of access to mental health care, and so many other related issues.

As the country faces major and rapid federal disinvestment in states and communities, these funding gaps will grow and increase the pressure on local decision-makers to make the most of each dollar while demonstrating evidence of impact.
