Sleep

A new study published in Chronobiology International suggests that night owls tend to exhibit higher levels of everyday sadism. Researchers provide evidence that a natural preference for staying up late is linked to enjoying others' pain.

Many teenagers sleep in on weekends to catch up on rest. New research associates this irregular schedule with differences in the physical structure and internal communication of the developing brain, which may relate to cognitive growth.

Do waking perceptual traits influence our sleep? New research indicates that people with synesthesia have unique dream patterns, providing evidence that our individual brain structures actively shape our imagination long after we fall asleep.

Job loss takes a hidden toll on the sleeping mind. By analyzing thousands of online dream reports, researchers found that unemployment strips away nighttime surprises and visual observations, mirroring the mental disengagement people experience during waking hours.

New findings suggest that social media use tends to lower heart rates in adolescents. The study indicates that digital devices likely disrupt sleep by changing schedules rather than by causing physical arousal before bed.

Using a bottle to soothe infants at bedtime may backfire. A new study finds this practice disrupts the ability to self-soothe, leading to shorter sleep duration and more frequent interruptions as the baby grows.

A new study reveals that getting sunlight before 10 a.m. significantly helps align sleep schedules. Researchers found that just 30 minutes of early exposure shifts the sleep midpoint earlier by 23 minutes.

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.
