Cheese and nightmares; new obesity framework reclassifies 1 in 5 overweight adults; why teens text and drive – Morning Medical Update

Cheese nightmares? There’s a link between lactose intolerance, consuming dairy and bad dreams

A new study in Frontiers in Psychology finds that people with lactose intolerance may be more likely to experience nightmares and poor sleep after consuming dairy. Researchers surveyed over 1,000 university students and found a strong link between gastrointestinal discomfort and disturbing dreams, especially among those with food allergies. While only a small percentage blamed food directly for nightmares, dairy was among the top culprits. The findings suggest that simple dietary changes could help some people sleep better — and dream more peacefully.

New obesity framework reclassifies 1 in 5 overweight adults

A new study in Annals of Internal Medicine finds that nearly 1 in 5 U.S. adults classified as overweight by BMI would be redefined as obese under a new European framework that factors in comorbidities and other body measurements. While these newly reclassified individuals had complication rates similar to those with obesity — including high rates of hypertension and diabetes — their mortality risk was on par with adults of normal weight. Researchers say the approach may allow for earlier, more sensitive detection of obesity-related disease.

Why teens text and drive

A new Mass General Brigham study finds that distracted driving is seen as a social norm among teens, with 21% admitting to using their phones while driving. Published in Traffic Injury Prevention, the research surveyed over 1,100 teens and conducted in-depth interviews to explore why they engage in risky behavior. Many cited peer behavior, perceived necessity (like GPS), and sleep deprivation as factors. Researchers suggest promoting “Do Not Disturb” mode and keeping phones out of reach to reduce risk.
