  From what we eat to how we cope with fatigue and stress, new research is shedding light on everyday health influences. A study published in the International Journal of Consumer Studies finds that TikTok has become a powerful force in shaping young consumers’ dietary decisions. Content shared by influencers is influencing everything from recipe choices and eating habits to decisions about where to dine. Meanwhile, researchers at Mass General Brigham are addressing a different modern challenge: exhaustion among early-morning shift workers. Clinical trials show that a drug called solriamfetol can significantly reduce excessive sleepiness in people whose workdays start before 7 a.m., a group often affected by fatigue that can impair focus, performance, and safety. Finally, doctors are urging calm when it comes to cortisol, often dubbed the “stress hormone.” While cortisol levels do fluctuate naturally throughout the day, true cortisol disorders are rare and difficult to diagnose. Physicians advise against self-testing or taking unproven supplements, recommending instead that people concerned about stress or hormone levels speak directly with their healthcare provider. Together, these findings highlight how science continues to refine our understanding of daily habits, health risks, and the importance of evidence-based guidance.

Depression doesn’t only live in the mind-it can take a real toll on the body. Changes in sleep, whether too little or too much, are common. Fatigue and exhaustion can make even everyday tasks feel overwhelming. Physical symptoms such as headaches, digestive issues, and changes in appetite or weight often accompany depression, reminding us that mental health and physical health are deeply connected. In today’s digital world, dating apps have become the go-to place for people searching for love. While they can be a great way to meet someone, clinical psychologists warn that digital dating can also trigger feelings of despair-especially when messages go unanswered or rejection feels constant. Endless swiping can become overwhelming, contributing to depression, anxiety, and stress. If you’re feeling burnt out or frustrated, it’s okay to take a break. Just don’t give up on connection altogether. We’ve also heard for years that too much video gaming can have negative effects, including physical problems from a sedentary lifestyle, anxiety, and emotional dysregulation. However, a new study published in JMIR offers a surprising twist: young adults who regularly played The Legend of Zelda: Breath of the Wild reported increased feelings of happiness, peace, calm, and purpose. It’s a reminder that balance-and how we engage with modern habits-matters just as much as the habits themselves.

It might not sound exciting, but everyday chores can actually give your health a boost. Cardiologists at the Cleveland Clinic say any activity that gets you moving counts as exercise. Vacuuming, mopping, and even hauling laundry help keep your body active—and it all adds up, even if you’re only moving for short bursts of time. Another topic getting attention is “time blindness.” Psychologists use this term to describe the difficulty some people have judging the passage of time, which often leads to chronic lateness. Anxiety, depression, and especially ADHD can make time management a real struggle. Experts say the best way to stay on track is through planning and preparation, such as building routines and setting reminders. Finally, while retirement is often seen as a reward after years of work, it can come with unexpected challenges. For some, leaving the daily routine behind can lead to loneliness or a loss of purpose. Mental health professionals recommend replacing work with meaningful activities—volunteering, adopting a pet, or staying socially connected—to maintain both emotional well-being and a sense of fulfillment.

Ever notice how you can feel hungry again not long after eating? Dietitians say the culprit is often the type of food you choose. Meals low in protein and high in refined sugars or heavily processed ingredients—think donuts, granola bars, or potato chips—are digested quickly. This rapid digestion causes a spike in blood sugar, followed by a crash that can trigger hunger soon after you’ve eaten. That’s why it pays to be cautious with foods labeled “no added sugar.” While the claim may be technically true, sugar can still be present under different names such as fructose, sucrose, dextrose, fruit juice concentrate, or rice syrup. Always check the nutrition label carefully, paying close attention to the grams of total sugars listed. Cold weather can also take a toll on your body, especially your joints. Low barometric pressure during colder months may constrict blood vessels, reducing blood flow to the fingers and toes and increasing joint pain or stiffness. Health experts recommend staying well hydrated and maintaining a healthy weight, both of which can help reduce inflammation and keep joint discomfort in check during chilly days.

Here’s a clean, polished rewrite as a short article: In many parts of the U.S., getting enough vitamin  - often called the “sunshine vitamin - can be a challenge, especially when sunlight is limited. Vitamin D plays a key role in bone health and mood regulation, and not getting enough can increase the risk of fractures and other health issues, according to the Cleveland Clinic. When regular sun exposure isn’t possible, experts recommend boosting vitamin D intake through foods such as fatty fish, eggs, mushrooms, and fortified dairy products. Nutrition research continues to reinforce the benefits of simple, familiar foods. Remember those classic commercials praising oatmeal for lowering cholesterol? A study published in Nature Communications confirms the claim still holds true. Researchers found that participants who regularly ate oats experienced reduced cholesterol levels - and notably, those positive effects were still present six weeks later. For post-workout soreness or the aches that follow heavy lifting, some people turn to Epsom salt baths. While scientists say there’s limited data on how effective they are, many people swear by them. Anecdotal reports suggest Epsom salts may help ease muscle soreness, reduce inflammation, and even soothe skin conditions like eczema and psoriasis - making them a popular at-home remedy after a long, strenuous day.

Strength training isn’t just for gym regular - it’s for everyone, and it’s especially important for women as they age. Research shows women face a higher risk of osteoporosis over time, and strength training is one of the most effective ways to protect bone health. Sports medicine doctors at the Cleveland Clinic recommend aiming for strength workouts twice a week, noting that the exercises don’t need to be complicated to be effective. Nutrition also plays a key role in seeing results from the gym. Increasing protein intake helps build and repair muscles and bones, and it can even support healthier skin and hair. Cottage cheese is an easy, protein-packed option: ounce for ounce, it contains about as much protein as Greek yogurt and can provide nearly half of your daily protein needs. If healthier hair is your goal, what you eat matters just as much as what you do in the gym. Greek yogurt and cottage cheese support hair strength with their protein content, while spinach delivers vitamin A, iron, beta carotene, folate, and vitamin C. Sweet potatoes are another standout, rich in beta carotene that helps the scalp produce sebum - keeping hair moisturized and less prone to dryness. Together, smart strength training and nutrient-rich foods can support stronger bodies and healthier hair from the inside out.

As colder weather sets in, staying safe and healthy goes beyond bundling up. Emergency Medicine physician Dr. Thomas Waters urges people to check their carbon monoxide detectors, especially as heaters and fireplaces are used more frequently. Carbon monoxide is a colorless, odorless, and tasteless gas that can cause serious health problems—and even be fatal—if it goes undetected. You may have also heard the old warning: “Don’t go outside in the cold, or you’ll get sick.” While it’s a common belief, healthcare professionals say cold weather itself doesn’t directly cause illness. However, lower temperatures can dry out the nose and throat, making it easier for viruses to enter the body. So while the cold isn’t the culprit, taking precautions like staying warm and washing hands is still important. Another hidden risk of winter is loneliness. When colder temperatures keep people indoors, social isolation can increase. The CDC reports that about one in three people experience loneliness, which psychologists say can lead to stress and raise the risk of serious conditions such as heart disease, stroke, and dementia. Loneliness can also affect brain health. The takeaway: stay connected. Volunteering, joining a class, or finding other ways to interact with others can make a meaningful difference during the winter months.

Recent research from England is shedding new light on smoking cessation, substance use treatment, and the effectiveness of cannabis-based medicines. A study led by Queen Mary University of London found that smokers who continue to vape after quitting traditional cigarettes are less likely to relapse. According to the researchers, individuals who used e-cigarettes as a quitting aid were more successful at permanently quitting smoking than those who relied on nicotine patches or gum. In related news, scientists are exploring new uses for established smoking-cessation medications. A study published by the Society for the Study of Addiction reports that varenicline, commonly known by its brand name Chantix, may also help reduce cannabis use among people struggling to quit. Researchers note that cannabis use disorder is becoming an increasing global concern, particularly as legalization expands in many parts of the world. Meanwhile, questions remain about the medical benefits of cannabis for chronic pain. A review published in the Cochrane journal found no clear evidence that cannabis-based medicines effectively relieve chronic neuropathic pain. While some patients using products containing both THC and CBD reported minor improvements, researchers concluded that the benefits were not significant enough to be considered clinically meaningful.

Medical dramas may be gripping, but they don’t always reflect reality. A study published in the American Heart Association’s scientific journal found that scripted U.S. television shows often misrepresent who is most likely to need CPR, disproportionately portraying white men as cardiac arrest victims. In real life, cardiac emergencies affect a far more diverse population, raising concerns that these portrayals could influence public perceptions of who needs lifesaving care. Health researchers are also raising new concerns about PFAs, often called “forever chemicals” because they persist in the environment and the human body. Already linked to hormone disruption and liver and thyroid disease, PFAs are now being associated with an increased risk of gestational diabetes. Researchers at Mount Sinai Hospital report that higher PFA exposure is connected to greater insulin resistance and increased insulin secretion during pregnancy. Meanwhile, parenting styles are under the microscope as well. A study from North Carolina State University suggests that overly involved parenting—sometimes described as “helicopter parenting”—may actually hinder a child’s ability to transition into independent adulthood. The research found that excessive parental involvement in decision-making can negatively affect children later in life, particularly when it comes to pursuing and succeeding in professional careers.

New research highlights how simple mental habits, everyday games, and even unusual foods may play a role in improving health and learning. Scientists at Virginia Tech report progress in helping people quit smoking by encouraging “future-focused thoughts.” By asking smokers to visualize the long-term damage smoking can cause to the lungs, heart, and other organs, researchers found participants were more successful at quitting—especially when this technique was combined with counseling and nicotine patches. Meanwhile, a study from the University of Oregon suggests that old-fashioned board games can sharpen children’s math skills. Researchers found that kids who played games with linear movement—where pieces advance along a numbered path—showed significant improvement in understanding and using numbers. Even short, 10-minute play sessions led to a 76 percent chance of better numerical skills. Finally, scientists in England are taking a closer look at bamboo, a food most commonly associated with pandas. Early findings suggest that bamboo may help control blood sugar, reduce inflammation, support gut health, and act as an antioxidant in humans. While the results are promising, researchers caution that more studies are needed before bamboo becomes a dietary trend. Together, these studies show how small changes in thinking, play, and diet could have meaningful benefits for health and learning.

Staying healthy during cold and flu season can be especially challenging for kids. The CDC reports record flu cases in many states, and experts say while illness can’t be fully prevented, steps like frequent handwashing, keeping sick children home from school, and getting flu vaccines can help slow the spread. Meanwhile, a study in AIMS Microbiology warns that commercial water dispensers and soda fountains can develop bacterial growth just days after cleaning, sometimes making them less safe than tap water, highlighting the need for regular maintenance. Finally, grief after losing a pet is more common and intense than many realize. Researchers found that 1 in 5 UK adults experienced prolonged grief disorder following the death of a pet, showing the deep emotional bonds people share with their animals.

Once jokingly dismissed as “grandma hobbies,” activities like knitting, cross-stitching, crocheting, baking, or even working on puzzles are getting new respect for their mental-health benefits. Psychologist Dr. Susan Albers of the Cleveland Clinic says these hands-on activities can create a calming state that’s hard to achieve by endlessly scrolling on a phone. Engaging in crafts, she explains, can lower stress hormones and help soothe the nervous system. As cooler weather sets in, many people also notice their skin becoming drier. Dermatologists say choosing the right moisturizer can make a big difference. Look for products that contain ceramides, which help rebuild the skin’s protective barrier. It’s also wise to avoid fragranced lotions, as scents can further dry out the skin. Applying moisturizer right after showering is ideal, but keep an eye on the water temperature—hot showers can strip the skin of its natural moisture. Sleep can also suffer when joint pain flares up. According to doctors cited by WebMD, proper sleep alignment is key. Try to keep your head, neck, and spine in a straight line while resting. Pillow choice matters: pillows that are too flat may let your head dip too low if you’re a side sleeper, while overly thick pillows can push your neck upward, increasing discomfort.

If you and your partner argue over how cool the bedroom should be at night, science may settle the debate. Researchers at Griffith University in Australia say keeping your room no warmer than 75 degrees Fahrenheit can help reduce stress during sleep—especially for adults aged 65 and older. A slightly cooler environment helps the body regulate temperature more efficiently, easing the workload on the heart as it circulates blood to the skin. Meanwhile, scientists at the University of St. Andrews in Scotland are finding surprising value in household plastic waste. Their research shows that plastic bottles and textiles made from PET can be recycled not only mechanically, but chemically. By breaking PET down at the molecular level, researchers believe it could be used to help synthesize anticancer medications, giving discarded plastics a powerful second life. Finally, experts say what you wear on your feet matters when you decide to get moving. Podiatrists warn that exercising in the wrong shoes can lead to injury. Runners should look for shoes with strong heel shock absorption, while walkers benefit most from footwear that is cushioned and stable. Choosing the right shoe for your activity can make workouts safer—and more comfortable.

If you’ve ever felt anxious after eating certain foods, you’re not imagining it. Dietitians say highly processed foods, fried items, fast food, and foods high in sugar or caffeine can all contribute to increased anxiety. If you notice these foods make you feel on edge, consider swapping them for more calming options. Foods rich in tryptophan—such as turkey and tart cherries—may help support a steadier mood, while magnesium-rich foods like nuts and bananas are known for their calming effects. Caffeine is another factor to keep in mind. For many people, coffee is a morning ritual and a helpful energy boost. However, healthcare experts recommend moderation. Aim to keep caffeine intake under 400 milligrams per day, or about four cups of coffee. Consuming too much caffeine can increase anxiety, disrupt sleep, and cause jitteriness. Diet also plays a role in hormone health, including testosterone levels. To naturally support testosterone, focus on getting enough protein from sources like lean beef, chicken, fish, eggs, and nuts. When protein intake is too low, the body prioritizes basic functions, leaving less testosterone available. Magnesium is important here as well, making leafy greens like spinach a smart choice. It’s also wise to limit alcohol, as regular drinking for as little as five days can lower testosterone levels. As always, consult your doctor before making significant dietary changes.

Social media influencers often warn against seed oils, but registered dietitians say the issue isn’t that simple. Seed oils themselves aren’t the main problem—it's the ultra-processed foods that usually contain them, such as packaged snacks and chips. Oils like grapeseed can still be part of a healthy diet when used in moderation, especially for cooking vegetables at home. Hair loss is often blamed on genetics, but many other factors can play a role. Certain medications, including blood thinners and anabolic steroids, may contribute to hair shedding. Hormonal shifts after pregnancy can also trigger temporary hair loss in women. In addition, nutritional deficiencies—such as low iron or protein intake—as well as high stress levels, can all affect hair health. Late-night cravings are another common struggle. Waking up and reaching for ice cream or chips may be a sign that you’re not eating enough during the day. Experts recommend including adequate protein with each meal to help you feel full and satisfied. It’s also important to watch out for mindless snacking, especially while watching TV, as boredom often drives these habits more than true hunger.
