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.
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 review of studies indicates that higher dietary fibre intake could enhance sleep quality by supporting beneficial gut bacteria. Researchers found lower diversity in gut microbiomes among people with sleep disorders, particularly reduced levels of anti-inflammatory bacteria. This points to potential dietary interventions, though more research is needed to confirm causality.
A night of poor sleep can leave one exhausted and disrupt eating habits, but expert Mariel Silva advises against self-blame and prioritizing rest. Hormonal imbalances boost cravings for unhealthy foods. Focusing on habits to improve nighttime sleep is essential.

Researchers have pinpointed five types of sleep patterns among young adults, each associated with specific mental health issues and brain activity differences. The study highlights how sleep disturbances, aid use, and short duration connect to cognition, emotions, and behaviors. These profiles offer new insights into sleep's broad impact on well-being.
