A long-term Finnish study has found that inconsistent bedtimes during middle age can nearly double the risk of serious cardiovascular events. People who varied their sleep times widely and spent less than eight hours in bed faced the greatest danger.

Sweden's Public Health Agency has released new recommendations to improve youth sleep, as nearly six in ten teenagers go to bed after 11pm – a sharp rise since the 1980s. The agency highlights later bedtimes and sleep difficulties as common issues. Advice includes reducing screen time and increasing physical activity.

New research from MIT reveals that when sleep-deprived individuals experience attention lapses, their brains trigger waves of cerebrospinal fluid to clear waste, mimicking a sleep-like process. This compensation disrupts focus temporarily but may help maintain brain health. The findings, published in Nature Neuroscience, highlight the brain's adaptive response to missed rest.

A new Oregon Health & Science University analysis of U.S. county data from 2019 to 2025 found that regularly getting less than seven hours of sleep per night is associated with shorter life expectancy. In the researchers’ models, the sleep–longevity link was stronger than associations seen for diet, physical activity and social isolation, and was exceeded only by smoking.

Researchers at the University of Chicago Medicine and Columbia University report that eating more fruits and vegetables during the day was associated with better sleep that night in healthy young adults. Meeting a five‑cup daily intake used to represent CDC recommendations was linked to an estimated 16% improvement in sleep quality, based on objective measures. The authors describe this as the first study to show a same‑day association between diet and objectively measured sleep.
