Health Headlines: Music, Itching and Food Safety
3w ago00:01:02Tap to summarizeA soothing lullaby may do more than help babies drift off to sleep. New research published by the BMJ Group suggests calming music in the Neonatal Intensive Care Unit (NICU) can benefit both infants and their parents. Studies found that playing gentle music can lower heart and respiratory rates, helping create a more relaxed environment during what is often a stressful time. Scientists have also uncovered new clues about why we eventually stop scratching an itch. Research from Brussels points to an ion channel called TRPV4, which helps the nervous system detect temperature, pressure, tissue stress and itching. The researchers say TRPV4 plays an important role in signaling the brain when it's time to stop scratching. And before tossing food because of an expiration or "sell by" date, experts say it may still be safe to eat. Dietitians recommend checking for signs of spoilage such as an off smell, mold, changes in texture or discoloration. One important exception is infant formula, which should always be discarded once it reaches its expiration date, regardless of how it looks or smells.

A Quick Look: How substances like alcohol and ketamine affect the body and mind
4w ago00:01:00Tap to summarizeResearchers have long been saying alcohol has a negative impact on the body. This is especially true if a person has more than 14 drinks per week - as this can increase their risk for colorectal cancer. A study published in the American Cancer Society Journal shows DNA cells can be damaged, along with the gut microbiome - which they say could be why a person's risk for colorectal cancer increases. == Some people use the anesthetic drug Ketamine recreationally for its hallucinogenic properties. But it has also become popular for some people to use to help treat problems they have with alcohol. Now, a new study published in the journal Addiction find contrary to earlier findings, the drug does not offer therapeutic benefits for alcohol addiction. == And there is great news when it comes to abstaining from alcohol use for those who have liver-related complications...researchers at the Medical University of Vienna say consistent and permanent abstinence from alcohol for these patients can actually reverse liver damage, even in the most advanced liver cirrhosis cases.

Medical AI, Brain Tech, and Sweeteners: What You Need to Know
4w ago00:01:00Tap to summarizeArtificial intelligence has found its footing in the medical world when it comes to detection of breast cancer, one of the most common cancers affecting women worldwide. Research published in the journal Oncoscience finds AI assisted mammography, for example detected 29-percent more breast cancers than conventional mammography interpretation. Researchers are also reporting a new approach to detecting awareness in unresponsive patients who can't speak or move after brain injury seems to be working. A study from the University of Bath in England found detection of brain activity through a wearable headset using an advanced combination of brain and computer technology. After numerous experimental sessions, researchers were able to uncover signs of consciousness in unresponsive patients. Meanwhile, artificial sweeteners are a go-to for a lot of people as they try to give up sugar. Researchers at Tufts University found that sugar substitutes can actually disrupt gut health and metabolism. Researchers say across 21 randomized clinical trials, they found the artificial sweeteners can affect blood sugar control and worsen insulin sensitivity.

Health News Roundup: Anxiety Apps, Melanoma Risk, and Salad Dressing!
4w ago00:01:02Tap to summarizeAnxiety Apps Offer Support, But Therapy Still Matters Mental health apps can help people living with Generalized Anxiety Disorder manage everyday anxiety, but they shouldn't replace professional treatment, according to German researchers. The study found that while digital tools can ease symptoms and provide coping strategies, they work best as a supplement to face-to-face therapy with a licensed mental health professional rather than a stand-alone solution. Family History May Be Key to Melanoma Risk While excessive sun exposure remains a major cause of melanoma, new research suggests genetics may play a larger role than previously understood. Researchers say identifying a family history of melanoma is critical because it can determine who qualifies for genetic testing. Eligibility is important, since insurance coverage for genetic testing often depends on established risk factors. Healthy Salads Can Lose Their Nutritional Edge A salad can be one of the healthiest items on the menu-unless the dressing undermines it. Nutrition experts say creamy dressings such as ranch, Thousand Island, and blue cheese can add significant amounts of calories, saturated fat, and sodium. Even some fat-free bottled dressings contain high levels of added sugar. A simple dressing made with olive oil and vinegar remains one of the healthiest ways to top a salad without sacrificing flavor.

Summer Health Watch: Protect Your Skin, Eyes, and Stomach
4w ago00:01:00Tap to summarizeSummer is the perfect time to enjoy the outdoors, but health experts say it's also important to protect yourself from seasonal risks that can affect your skin, eyes, and digestive system. When people think of skin cancer, they often check areas like the face or neck. But one of the most common forms of skin cancer, basal cell carcinoma (BCC), can also develop on the hands and fingers. Because these lesions can resemble moles or large freckles, they are sometimes misdiagnosed. A new report published in the journal Skin highlights the importance of monitoring any darkened or crusting lesions on the hands and having them evaluated by a healthcare professional. Protecting your eyes is just as important as protecting your skin. Eye doctors say the price of your sunglasses matters far less than the protection they provide. Look for lenses labeled with 100% UV protection, also known as UV400, to help shield your eyes from harmful ultraviolet rays. Polarized lenses are also a good choice for reducing glare. And while you're taking steps to stay safe in the sun, don't forget to guard against stomach viruses while traveling-especially on cruise ships. Illnesses like norovirus spread easily in close quarters. Frequent handwashing, eating only properly cooked foods, and avoiding touching your face can help reduce your risk of getting sick while on vacation.

Today's Health Roundup: Fitness Devices, Mocktails and Reality TV
Jun 2600:01:02Tap to summarizeFitness watches have become a daily tool for millions of people, tracking everything from steps and workouts to sleep and calories burned. But how accurate are they? A recent study from the University of Mississippi found that while devices such as the Apple Watch are generally reliable for basic health tracking, they can be less accurate when measuring heart rate. Researchers say wearable technology is a useful tool for monitoring overall wellness, but it should not replace professional medical equipment or clinical evaluations. Meanwhile, the "sober curious" movement continues to gain popularity as more people choose to drink less or skip alcohol altogether. However, social pressure can still make it difficult in group settings. Addiction specialists recommend planning ahead for these situations. Ordering a mocktail or another non-alcoholic beverage can help people feel included while reducing the chances that others will offer them a drink. Reality television also remains a major source of entertainment, with some viewers becoming deeply invested in their favorite stars. Psychologists say the appeal comes from its ability to provide a temporary escape from everyday life—comparing it to "junk food for the brain." While enjoying reality TV can be harmless fun, experts encourage viewers to maintain a healthy balance and avoid letting it consume too much of their time.

Health Notes: Tongue Brushing, Beating Jet Lag, and Weather-Triggered Migraines
Jun 2500:01:00Tap to summarizeMost people know they should brush their teeth twice a day-but what about their tongue? Dental experts say brushing your tongue is an important part of oral hygiene. It can help reduce bacteria in the mouth and remove the coating that often causes bad breath. Experts say you can use your regular toothbrush or a tongue scraper to get the job done. Planning a long-distance vacation? The excitement of travel can quickly be overshadowed by jet lag. Sleep specialists say the best way to prepare is by getting quality sleep in the days before your trip. They also recommend gradually adjusting your sleep schedule and meal times to match your destination’s time zone a few days before departure. Once you arrive, spending time in sunlight can help reset your body's internal clock. For migraine sufferers, triggers can include things like caffeine, strong odors, and even the weather. Headache specialists say changes in barometric pressure-such as when temperatures drop rapidly-can contribute to migraines. Hot weather can also be a factor because dehydration increases the risk of developing a migraine. Staying hydrated and monitoring weather changes may help reduce the chances of an attack.

New Research Highlights Advances in AI, Nutrition, and Sustainable Packaging
Jun 2400:01:01Tap to summarizeA new study published in the journal Radiology suggests artificial intelligence can significantly improve breast cancer risk prediction by analyzing screening mammograms. Researchers found that deep learning models can evaluate the entire mammogram image to generate more accurate five-year breast cancer risk scores than traditional risk assessment methods, including breast density measurements. Scientists say the technology harnesses the predictive power of medical imaging to enhance risk assessment and support earlier disease prevention strategies. Can plant-based protein build muscle better than meat? According to a study published in the American Journal of Clinical Nutrition, the answer is no. Researchers compared muscle protein synthesis in participants who consumed a meal of rice and beans or a post-workout shake with those who ate a post-workout meal containing 20 grams of lean pork. The results showed no significant differences between the groups, suggesting plant-based protein can be just as effective as meat protein for supporting muscle growth after exercise. Packing peanuts are typically made from polystyrene, a plastic material that can be difficult to recycle. Researchers with the American Chemical Society have developed a more sustainable alternative using sawdust. The new foam is created by combining sawdust with plant-based binders and coating the material in beeswax to make it water-resistant. Scientists say the biodegradable packing material could provide a safer and more environmentally friendly replacement for traditional plastic-based packing peanuts.

New Advances in Water Safety, Wound Healing, and Teen Smoking Research
Jun 2300:01:01Tap to summarizeResearchers are making strides in tackling some of today’s biggest health and environmental challenges. Scientists at the University of Florida have developed a new way to remove PFAS, often called “forever chemicals,” from water. The team created a gel-like material they describe as “molecular Velcro” that uses electrical charges to trap PFAS molecules. The gel can be reused multiple times because the captured chemicals can be flushed out using common solvents. Meanwhile, researchers at the Terasaki Institute for Biomedical Innovation have unveiled an injectable hydrogel designed to speed the healing of chronic wounds. Made from silk and compounds derived from the kudzu plant, the material promoted complete wound closure within 72 hours during testing, offering promise for patients with slow-healing injuries. In another study, scientists at the University of Nebraska–Lincoln found that fathers may have a stronger influence on whether teenagers use tobacco products than mothers. Tracking 230 children from preschool through adolescence, researchers discovered a significant link between fathers’ smoking habits and their children’s later tobacco use. The team suggests this may be because fathers often exert a different type of influence on behavior, while mothers are more commonly associated with caregiving roles.

Green Spaces, Plastic Exposure, and Life After Caffeine: New Insights for Better Health
Jun 2200:01:01Tap to summarizeSpending just 15 minutes in a green space could provide a significant boost to mental health, according to researchers at Stanford University. Whether it's a large urban park or a small "pocket park," the study found that access to greenery can benefit people dealing with a wide range of mental health challenges. Researchers say the findings should encourage urban planners and policymakers to prioritize green spaces when designing housing and city developments. Meanwhile, concerns continue to grow about microplastics and nanoplastics being found in the human body. Experts say these tiny plastic particles may affect hormones, metabolism, and could even contribute to weight gain. To reduce exposure, healthcare professionals recommend using microwave-safe food containers and choosing alternatives such as glass, metal, or ceramic for food storage whenever possible. And for those considering cutting back on caffeine, there may be some surprising benefits. According to WebMD, giving up coffee can lead to better sleep, reduced anxiety, fewer trips to the bathroom, lower blood pressure for some individuals, and even whiter teeth. However, the transition isn't always easy. Common caffeine withdrawal symptoms can include headaches, fatigue, sleepiness, and irritability before the benefits begin to take hold.
