Sleep

Overweight teens experience greater cognitive impairments from sleep restriction compared to their healthy-weight peers, particularly in global cognition, fluid cognition, cognitive flexibility, and attention, according to new research.

A study found that older adults identifying as 'night owls' have higher cognitive scores than morning types. Normal sleep duration (7-9 hours) is linked to better cognition, while excessive sleep correlates with lower cognitive performance.

A study found that high-quality sleep during the weekend improves mental reattachment to work on Monday, reducing exhaustion throughout the workweek.

New research has found that 24 hours without sleep impairs attention and rapid information processing, causing a significant increase in errors. Sleep is crucial to restore these vital cognitive functions.

Reading on a smartphone without a blue-light filter significantly reduces melatonin levels, with adults experiencing prolonged suppression. Blue-light filters and printed books have less impact on melatonin levels.

Staying up late, even if you're a night owl, is linked to higher risks of depression and anxiety. This surprising study suggests that an earlier bedtime could improve mental health, regardless of natural sleep preferences.

Researchers have found that the brain weakens synaptic connections formed during wakefulness primarily in the first half of the night, supporting the idea that sleep acts as a reset for the brain.

Cognitive behavioral therapy improved sleep onset and duration for adolescents with anxiety disorders. Teens took less time to fall asleep and slept longer after therapy, though nighttime awakenings remained unchanged.

A 12-week Tai Chi exercise program improved sleep quality and reduced anxiety and depression in older adults with insomnia. The intervention also enhanced functional connectivity between the brain's motor network and the cerebellum.

Inconsistent sleep schedules in adolescents are linked to poorer academic performance and more behavioral issues at school, underscoring the importance of regular sleep patterns for educational success and well-being.

A recent study found that men, but not women, with shorter sleep durations performed worse on wayfinding tasks. The findings were published in Scientific Reports.

Researchers discovered that deep sleep quality, specifically in the brain's right temporoparietal junction, correlates with higher prosocial behaviors like cooperation and charity.

Researchers have found that a single dose of creatine can temporarily enhance cognitive functions impaired by sleep deprivation. This study suggests creatine as a potential non-stimulant alternative for boosting brain performance when sleep is compromised.

Individuals who sleep more on weekends, known as weekend catch-up sleep, show significantly fewer depressive symptoms, particularly men and adults under 65 who sleep less during weekdays.
