Sleep

A new study reveals that waking mind wandering is just as densely packed with bizarre elements as nighttime dreaming. While dreams feature slowly transforming impossibilities, daydreams are marked by abrupt jumps in logic.

New research indicates that dreams often act as a simulation for social hurdles. By analyzing hundreds of dream reports, scientists found that themes like status and self-protection frequently organize the content of our sleep narratives.

People who regularly practice advanced meditation techniques exhibit brain activity patterns during sleep that appear noticeably younger than their actual age. Researchers suggest these habits might help protect against cognitive decline, though questions about exact causes remain.

Compulsive social media habits are closely linked to later symptoms of depression and anxiety, and new research suggests poor sleep is a major factor. Protecting your nightly rest might be key to maintaining your psychological wellbeing.

Wearable trackers show a new parent's actual sleep time doesn't predict their mental health. Instead, a new study finds that psychological distress actually worsens perceived sleep quality over the first year postpartum for both parents.

While heavy coffee drinking is often blamed for long restless nights, a new genetic analysis reveals that habitual caffeine consumption mainly boosts daytime alertness without inherently causing chronic insomnia.

Trying to drown out a noisy street with pink noise? You might be making things worse. New research indicates combining environmental noise with continuous pink noise degrades overall sleep architecture more than the traffic alone.

Scientists have discovered that poor sleep amplifies negative emotions in individuals with alcohol use disorder. Imaging shows that insomnia activates neural networks linked to rumination, suggesting sleep treatments could greatly improve emotional well-being during recovery.

Using wearable sleep trackers and daily smartphone brain games, researchers discovered that waking up frequently during the night leaves dementia-free older adults with significantly slower cognitive processing speeds the very next day.

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.
