Sleep

A new review of multiple studies suggests that regular physical activity can significantly lower anxiety and depressed moods in people with chronic insomnia. The findings also point to improved overall sleep quality.

A recent study published in Neuroscience of Consciousness provides evidence that dreaming about a specific problem helps people find solutions. Researchers used sound cues during sleep to successfully guide dream content toward unsolved puzzles.

A new neuroimaging study suggests that people who frequently control their dreams share distinct structural brain patterns. These networks bridge the areas responsible for self-reflection, visual imagery, and cognitive control.

A new study in Communications Biology provides evidence that a psychedelic drug induces a hybrid sleep-wake state in active mice. This unusual brain activity suggests a potential mechanism for how psychedelics might help remodel neural connections.

Sleep sex is a real medical condition. Explore sexsomnia symptoms, risk factors, brain wave research, and potential management strategies.

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.
