For years, federal physical activity guidelines have told Americans how much time they should spend moving each week: at least 150 minutes, or 75 minutes if workouts are particularly vigorous. But the popularity of wearable fitness devices has made many people obsessively track their step counts instead, often shooting for the goal of 10,000 per day (even though some studies suggest that number is arbitrary).Is the length of your workout or your daily step count a better measure of wellness?“Both are good metrics,” says Dr. Rikuta Hamaya, a preventive-medicine researcher at Brigham and Women’s Hospital in Boston and lead author of the new study. But Hamaya and his colleagues wanted to know if one was better than the other, so they designed a head-to-head comparison. The resulting study, pu...

(WASHINGTON) — Cyberattacks against water utilities across the country are becoming more frequent and more severe, the Environmental Protection Agency warned Monday as it issued an enforcement alert urging water systems to take immediate actions to protect the nation's drinking water.About 70% of utilities inspected by federal officials over the last year violated standards meant to prevent cyberthreats, the agency said. Officials urged even small water systems to improve protections against cyberattacks, noting that recent assaults from adversarial nation states like Russia and Iran have impacted water systems of all sizes.Some water systems are falling short in basic ways, the alert said, including failure to change default passwords or cut off system access to former employees. Because ...

People with HIV can breastfeed their babies, as long as they are taking medications that effectively suppress the virus that causes AIDS, a top U.S. pediatricians’ group said Monday in a sharp policy change.The new report from the American Academy of Pediatrics reverses recommendations it had in place since the start of the HIV epidemic in the 1980s.It recognizes that routinely prescribed drugs can reduce the risk of transmitting HIV via breast milk to less than 1%, said Dr. Lisa Abuogi, a pediatric HIV expert at the University of Colorado and lead author of the report.“The medications are so good now and the benefits for mom and baby are so important that we are at a point where it is important to engage in shared decision-making,” Abuogi said.The drugs, known as antiretroviral therapy, d...

The summer of 2023 was the hottest on record since 1850, and this summer could be just as sweltering. That puts older adults—a group especially vulnerable to heat-related illnesses—at elevated risks for a number of health conditions and outcomes. Older people are less able to regulate changes in body and environmental temperatures, and higher temperatures put them at increased risk of dehydration, heat stroke, blood pressure changes, muscle cramps, and dizziness.These issues are likely to become far more prevalent than they currently are. From now until 2050, the number of people 60 years or older will double to nearly 2.1 billion, making up 21% of the global population, according to projections from the World Health Organization. Giacomo Falchetta, a scientist at the Euro-Mediterranean Ce...

Through the ages, humans have fueled their most physically demanding efforts with meaty proteins. Ancient Greeks loaded up on red meat before Olympic contests, and medieval knights recovered from war with venison and pork. The tradition continues today, with world-record-setting weightlifters breakfasting on chicken thighs, eggs, and bacon.But experts recommend that the modern, average person eat several other foods before and after tough workouts, even if the knights may have tossed them from their castle windows.The missing ingredientsDuring exercise, blood carries the nutrients we’ve consumed to our strained muscles, where they’re absorbed. “We are what we eat,” says Keith Baar, a molecular exercise physiologist at the University of California, Davis. “And when we exercise, we’re more o...

Cases of a new group of mpox viruses are rising, potentially posing a risk to people around the world, according to health officials at the U.S. Centers for Disease Control and Prevention (CDC). So far, the cases have been centered in the Democratic Republic of Congo (DRC) and have not spread beyond Central African countries where the virus remains endemic, the CDC wrote in a report on May 16. But health officials are concerned because this group of viruses—known as clade I mpox viruses—is known to cause more severe illness than the clade II viruses responsible for the previous mpox outbreaks in 2022, which originated in Nigeria. Clade I mpox viruses have a higher fatality rate—killing anywhere from 1.4% to more than 10% of infected people—than clade II, which has a 0.1% to 3.6% mortality ...

If you’re an undocumented immigrant in Tennessee, you don’t have a lot of options when it comes to birth control. You can’t get an abortion—it’s been banned with very limited exceptions since 2022. You can’t get services from state public-health clinics, which lost federal funding with the abortion ban. The state has backfilled the funding, but a Tennessee law prohibits that money from being used for family-planning services for people without legal status. One thing you can do is reach out to a nonprofit called A Step Ahead, which will pay for you to get a long-acting reversible contraceptive (LARC), like an intrauterine device (IUD) or an implant that goes into your arm. But there’s a problem, some reproductive justice advocates say. In many regions of the state, including Memphis and N...

Sue Gray, 59, has been sick half her life. But it took two decades to confirm why.When Gray was 30 and living with her then-husband in the middle of the woods in upstate New York, she felt a tick on her scalp one day after taking a shower. Her former husband plucked it off with tweezers, and “that was the end of that—for that day,” Gray says.Over the next few months, however, Gray’s health began to decline. She suffered frequent respiratory infections and developed a twitch in her eye. Then, a few weeks after the twitch began, she felt the sensation of ants crawling up and down her legs, even though nothing was there. That made Gray nervous enough to book an appointment with a neurologist. Remembering her recent tick bite, Gray asked to be tested for Lyme disease—but the results came back ...

New York City will host its very first National Urban Rat Summit this fall, Mayor Eric Adams announced Wednesday.The summit will invite experts like academic researchers and municipal pest control managers to come together and share strategies on rodent mitigation and “advance the science of urban rat management,” the city said in a press release. Experts from across the country—including Boston, New Orleans, and Seattle—will be invited to attend the summit, which will be held on Sept. 18 and 19.“New Yorkers may not know this about me—but I hate rats, and I’m confident most of our city’s residents do as well,” Adams said in the press release. “The best way to defeat our enemy is to know our enemy. That’s why we’re holding this inaugural summit, to bring experts and leaders from across the ...
