A new study links sleep loss to the thinning of the myelin layer, which slows signal transmission in axons. Restoring cholesterol homeostasis reverses this.

Researchers have figured out how psoriasis can quietly turn into joint disease for some patients. Immune cells formed in inflamed skin can travel through the blood and reach the joints, where they sometimes trigger inflammation. The key difference lies in the joint’s ability to keep those cells in check. This insight could help doctors identify warning signs early and prevent lasting joint damage.

A recent study found that a short afternoon nap may offer brain health benefits, such as clearing the mind and improving learning.

Popular weight-loss drugs like Ozempic and Wegovy can dramatically curb appetite, but experts warn many users are flying blind when it comes to nutrition. New research suggests people taking these medications may not be getting enough guidance on protein, vitamins, and overall diet quality, increasing the risk of muscle loss and nutrient deficiencies.

A recent study suggests that pink noise may interfere with REM sleep nd reduce overall sleep quality. The researchers say that using earplugs may be a safer alternative to pink noise.

Collagen pills sound like a shortcut to younger skin, but solid evidence doesn’t back them up. Higher-quality studies show little benefit, and your body doesn’t absorb collagen in the way ads suggest. Some supplements may even pose safety concerns and lack proper testing. Experts recommend focusing on proven habits like sunscreen, retinoids, and a nutrient-rich diet instead.

Where your body stores fat may matter just as much as how much you carry—especially for your brain. Using advanced MRI scans and data from nearly 26,000 people, researchers identified two surprising fat patterns tied to faster brain aging, cognitive decline, and higher neurological disease risk. One involves unusually high fat buildup in the pancreas, even without much liver fat, while the other—often called “skinny fat”—affects people who don’t appear severely obese but carry excess fat relative to muscle.

Ozempic, Mounjaro, and Zepbound can drive impressive weight loss, but stopping them is often followed by rapid weight regain. Researchers found that people regain weight faster after quitting these drugs than after diet and exercise alone. Improvements in heart health and diabetes risk also tend to reverse within a few years. The results suggest long-term success may require more than medication alone.

Colorectal cancer is now the leading cause of death due to cancer for Americans under 50, according to a new report from the American Cancer Society (ACS). The report found that colon cancer death rates are rising annually, while deaths from other major cancers have declined.

For thirty years, I believed I had to be smaller. Now I’m learning to be stronger, and I feel better than I ever have.

Scientists at Stanford Medicine have discovered a treatment that can reverse cartilage loss in aging joints and even prevent arthritis after knee injuries. By blocking a protein linked to aging, the therapy restored healthy, shock-absorbing cartilage in old mice and injured joints, dramatically improving movement and joint function. Human cartilage samples from knee replacement surgeries also began regenerating when exposed to the treatment.

A new review has shown that menopause hormone therapy is not linked to dementia risk.

All forms of exercise help you live longer, but some activities come with extra benefits.

Emotional intelligence is a vital dimension of our lives that enhances how we relate to ourselves and others.

Sleep isn’t just about feeling rested—it may be one of the strongest predictors of how long you live. Researchers analyzing nationwide data found that insufficient sleep was more closely tied to shorter life expectancy than diet, exercise, or loneliness. The connection was consistent year after year and across most U.S. states. The takeaway is simple but powerful: getting seven to nine hours of sleep may be one of the best things you can do for long-term health.

Global cancer cases have surged dramatically, doubling since 1990 and reaching 18.5 million new diagnoses in 2023. Deaths have also climbed to over 10 million a year, with the steepest increases hitting low- and middle-income countries. Without urgent action, researchers project more than 30 million new cases annually by 2050. Alarmingly, around four in ten cancer deaths are tied to preventable risks such as smoking, poor diet, and high blood sugar.

Plus two ways to be more resilient, starting today.
