Sleep

New research suggests that older adults with chronic sleep issues tend to live shorter lives and spend less time with normal memory and thinking skills.

A new twin study reveals that individuals with maladaptive personality traits, such as negative affectivity and detachment, are more likely to report poor sleep quality. Genetics appear to play a partial role in this association.

A new study published in Sleep Health reveals that frequent night waking is linked to immediate reductions in cognitive speed. The findings suggest that sleep continuity may be more critical than duration for aging brains.

A new study suggests that taking a two-hour nap during a night shift can restore brain connectivity. The findings indicate that napping reverses some cognitive deficits associated with sleep deprivation in nurses.

A new study reveals that deep sleep physically shifts where the brain processes memories. Researchers found that spending more time in slow wave sleep moves recall activity to the temporal lobe, boosting retention.

The glymphatic system serves as the brain’s waste clearance mechanism. Emerging research suggests that sleep plays a critical role in flushing out metabolic toxins associated with neurodegenerative diseases like dementia.

Young people seeking a fitness boost may be sacrificing essential rest. Research links pre-workout supplement use to a higher likelihood of severe sleep deprivation in adolescents and young adults.

New research confirms the Moon subtly shapes human sleep and biology. However, the rise of LED lighting and smartphones is severing this link, drowning out the natural contrasts that once structured our biological time.

New research involving nearly 400,000 adults links healthy sleep patterns to a lower likelihood of developing heart, kidney, and metabolic diseases. The study suggests mental health factors may partially mediate this association.

New research suggests that while habitual coffee consumption shortens sleep duration, it increases deep sleep intensity. This indicates the brain may adapt to chronic caffeine intake to ensure restoration.

Chronic sleeplessness may result from a failure of the brain’s internal timing. A study in Sleep Medicine indicates that individuals with insomnia lack the strong circadian cues needed to downregulate mental activity for sleep.

While the dangers of sleep deprivation are well-known, recent studies suggest sleeping over nine hours is also linked to health risks.

Your attitude toward the past and future may shape your daily rhythms. A new study suggests this connection influences depressive symptoms, linking your mindset directly to your well-being.

An international team has created the largest-ever public database of brain activity and dream reports. A first analysis reveals that during deep-sleep dreams, the brain exhibits patterns resembling wakefulness.

A new study finds that the brain’s energy use and blood flow change in coordinated yet region-specific ways during sleep. Sensory areas remain active, which may help explain how we stay alert to important sounds while asleep.
