Why It’s Important To Stay Hydrated During Exercise, Even in Winter

Don’t Sweat It? When temperatures drop, it’s easy to let hydration slide. You’re sweating less, you may not feel as thirsty, and when it’s cold outside, cold water doesn’t seem appetizing. But staying hydrated during your workouts, especially longer and more challenging ones, is important to keep your body operating at full capacity — even if it doesn’t necessarily make you run faster or lift heavier. The Study: A new systematic review examined 24 studies involving 225 total participants to investigate how drinking during endurance exercise affects performance. In all of the studies, participants performed at least 60 minutes of continuous aerobic exercise. The researchers found that hydration was associated with a lower core body temperature and reduced heart rate, two factors that are generally associated with better aerobic exercise performance. Interestingly, however, there was no clear improvement in timed performance, such as completing a set distance faster. Takeaway: Think of hydration as helping your body handle the workload, not necessarily helping you win the race. Drinking water during prolonged exercise may reduce cardiovascular and thermal strain, making it easier to keep going. Keep in Mind: Most studies in the review were small, only 20 participants were women, and researchers […]

The Resurgence of the Women-Only Gym

The Trend: Women-only gyms are having a comeback, but this time, it’s less about step classes and leotards and more about lifting heavy. After fading from popularity in the 2000s and 2010s, women-focused fitness spaces are re-emerging as more women embrace strength training. The new wave includes boutique studios, coached weightlifting sessions, and welcoming spaces designed to make the weight room feel less intimidating. What People Are Saying: The appeal goes beyond avoiding unwanted attention. Women-only gyms offer a chance to learn new movements, build confidence, and take up space without feeling watched or judged. And it stems from a real need: a 2025 study of nearly 300 women found that participants reported feeling scrutinized for their appearance and performance, navigating harassment, and sometimes struggling to access equipment or be taken seriously. What to Know: Unlike the ’90s-era Curves model, which often centered on calorie-burning circuits and weight loss, today’s women-only gyms are putting progressive strength training, expert coaching, and community front and center. The shift reflects a broader movement toward building muscle for longevity, bone health, and everyday strength, not just changing how your body looks. For many women, the real draw is a place where women can focus […]

The Best Moves for Building Stronger Bones

Resistance training doesn’t just build muscle. Bone-loading exercises like squats, deadlifts, and jumping rope can improve bone mineral density and help lower your osteoporosis risk.

Will We See HYROX In the Next Olympics?

The Trend: What started in Germany in 2017 as a fitness race has grown into a global competition, and HYROX now has its sights on the Olympics. The sport combines eight 1-kilometer runs with eight workout stations, including sled pushes, rowing, burpee broad jumps, and weighted lunges. And on October 28, HYROX and World Triathlon announced a partnership officially recognizing hybrid racing as a discipline under the governing body’s umbrella. Next, they’ll develop three competition formats (Fast, Ultra, and Ultimate) and pursue spots in multisport events, a stepping stone toward Olympic and Paralympic inclusion. What People Are Saying: HYROX’s popularity has helped it earn a reputation as a legitimate competitive sport, but its Olympic ambitions aren’t winning everyone over. Some established triathletes have questioned the partnership, including British Olympic champion Alex Yee, whose social media poll showed 82% of respondents opposed the move. Others, including Polish Olympic triathlete Roksana Slupek have questioned what the two sports have in common. Another British triathlete, Max Stapley, wrote on Yee’s Instagram post: “This is crap.” What to Know: There’s no confirmed Olympic debut yet, and the partnership’s full operational framework is still to come. But the move signals that hybrid fitness is gaining […]

The Dark Nutrition Crowd Is Ditching Vegetables for Raw Buffalo Brains

The Trend: One influencer eats everything raw, including buffalo brains and the occasional roadkill rabbit. Another credits raw egg yolks for her great skin and hair. Welcome to dark nutrition, where the main premise is that most of what society has told us about food is all wrong. Most followers of the trend go to podcasts and social media for advice and distrust doctors and public health officials. So even previously undisputed advice (think “eat your vegetables”) is up for debate. What People Are Saying: The movement has surged over the past five years alongside vaccine hesitancy and the Make America Healthy Again movement. Many followers turn to it after chronic illnesses and nagging symptoms that medication didn’t seem to fix, and they trust an approach where personal experiments show better results than big studies. What to Know: Experts agree that nutrition science is tough to pin down. We do know plenty, however. For example, there’s lots of evidence that vegetables are broadly good for us and raw meat carries a serious risk of bacterial contamination. The attraction to dark nutrition may come down to wanting clear answers in a field where the honest response is often “it depends.”

How Workplace Stress Could Be Changing the Way You Eat

A Lot on Your Plate: Most of us want to eat healthier, but the best intentions and even best-laid plans often fall short when it comes to our diets. While a lack of willpower is often blamed, new research has pinpointed why our work environment may have more impact on our eating patterns than just our personal choices. The Study: Researchers wanted to investigate the relationship among people’s eating habits, nutritional knowledge, and stress. They used a mixed-method design to survey 232 university employees in Saudi Arabia. Most of them had a medium to high level of nutrition knowledge, but many of them also made poor dietary choices: skipping meals, inadequate consumption of fruit and vegetables, and eating at irregular times. The Takeaway: Higher nutritional knowledge correlated with healthier eating patterns. Higher stress levels were associated with the poor dietary choices — particularly not eating enough fruit and vegetables. Researchers say the findings shift focus from willpower and personal responsibility and onto workplace stress and its effect on our diet and overall health, citing a few specific culprits: back-to-back meetings, heavy workloads, and limited access to healthy foods. Keep in Mind: Data was self-reported and established a correlation, not causation, […]

Why Permanent Daylight Saving Time Might be a Bad Idea for Your Health

You Should Know: When clocks fall back tomorrow, evenings will get darker earlier. If you wish we could keep that evening light year-round, there may be a trade-off: Our internal clocks rely on light, and experts say permanent daylight saving time could mean darker winter mornings, potentially disrupting circadian rhythms that regulate sleep, hormones and metabolism. Going Deeper: Morning light helps synchronize our internal body clocks, while evening light can delay the release of melatonin, which helps regulate sleep. The American Academy of Sleep Medicine argues that permanent DST could worsen this mismatch by creating darker mornings and brighter evenings. Research also suggests that permanent DST could lead to declines in heart health and sleep deprivation in teens. On the other hand, dark winter evenings can feel draining, and seasonal affective disorder (SAD) is a recognized form of depression associated with seasonal changes. More evening daylight could make it easier to spend time outdoors after work. But the evidence doesn’t suggest that permanent DST would improve mental health. A 2026 systematic review of 157 studies found no clear, consistent effects on psychiatric outcomes. Takeaway: Sleep experts generally favor permanent standard time because it better aligns daylight with our body clocks. Bottom Line: The evidence […]

Here’s How Your Dreams Can Help You Solve Problems

Let Your Mind Wander: Stuck on a problem you can’t seem to crack? Your sleeping brain might offer a fresh perspective. Dream incubation — the practice of focusing on a question before bed in hopes it shows up in your dreams — isn’t a guaranteed route to an epiphany, but it’s a low-stakes (and arguably fun) way to explore your situation. How to Do It: For NPR, Health & Science Correspondent Allison Aubrey outlines a simple approach to giving your dreams a nudge. Before bed, choose a specific problem you’re wrestling with, and ask yourself a good question about it (avoiding yes-or-no questions). Spend a few minutes reflecting on it: picture the problem, write it down, or repeat it to yourself as you settle in. Keep a notebook nearby. When you wake up, jot down any dreams, images, feelings, or ideas you remember before they fade. Later, revisit your notes with a curious mind. A dream may not hand you an answer, but it could spark a new angle. The Benefits: Research into dreaming and problem-solving suggests sleep may help us make unexpected connections, but dream incubation is far from settled science. Any insight should be viewed as inspiration, not […]
