Morning naps may flag higher mortality risk in older adults

Older adults who took longer and more frequent daytime naps, especially in the morning, had a higher risk of all-cause mortality in this prospective cohort study using actigraphy-based nap tracking. Variability in nap duration from day to day was not associated with mortality after full adjustment.

Teen cannabis use linked to slower growth in memory and thinking

Researchers from University of California San Diego have found that teenagers who begin using cannabis show slower gains in thinking and memory skills as they grow. The study, published on April 20, 2026 in Neuropsychopharmacology, analyzed data from more than 11,000 participants in the Adolescent Brain Cognitive Development (ABCD) Study, the largest long-term study of brain development in U.S. youth.

Climate change could make humidity-driven heat risks more dangerous, study finds

Researchers analyzing 2.46 million ambulance dispatches across 13 Chinese cities found that humidity can intensify the health risks linked to both hot and cold temperatures, with cold-dry and warm-wet conditions posing the greatest risks. Future climate projections suggest compound temperature-humidity events will become more frequent and increasingly shift health burdens toward heat-related events in China.

Psychedelic use is associated with major life changes across 10 domains

Researchers created a new questionnaire to measure major life changes linked to psychedelic use and found that most surveyed adults reporting naturalistic psychedelic use said psychedelics had influenced at least one major change in their lives. These changes most often involved goals, values, and spirituality, were usually rated positively, and were more commonly reported by people with more frequent use.

New findings explain why eccentric training prevents common sprinting injuries

Hamstring injuries are among the most common injuries in sports, particularly in activities involving sprinting and rapid acceleration. They account for roughly 10 % of injuries in field-based sports and often result in significant time away from competition. Despite their frequency, the mechanisms underlying the effectiveness of certain training programs in preventing these injuries remain poorly understood.

Study links ultra-processed food intake to poorer thigh muscle quality

A Radiology study of 615 adults at risk for knee osteoarthritis found that higher ultra-processed food intake was associated with greater fat infiltration in thigh muscles on MRI, a marker of poorer muscle quality. The association remained after adjustment for BMI, was stronger in models using abdominal circumference, and did not differ significantly by sex.

Loneliness is linked to higher risk of degenerative heart valve disease

Adults who reported feeling lonely had a higher risk of developing degenerative heart valve disease, even after accounting for traditional heart disease risk factors and genetics, according to new research published today in the Journal of the American Heart Association, an open-access, peer-reviewed journal of the American Heart Association.
