Sleep

A recent study delves into how consecutive nights of alcohol consumption before sleep alter sleep architecture, revealing increased deep sleep early on but reduced REM sleep and more disturbances later. This nuanced insight highlights the body's adaptation over time, underscoring...

A study reveals poor sleep boosts use of humor and curse words. Fatigue may drive us to seek physiological uplift through arousing language, suggesting our verbal choices are influenced by how well we rest.

A study found that hearing relaxing words during sleep slows down the heart, deepening sleep quality. This reveals our hearts stay tuned to external cues even in slumber, highlighting a novel link between auditory stimuli and sleep's physical dimensions.

Through a novel verbal associative task, researchers demonstrated how sleep strengthens weak connections and forms new associations between event elements, enhancing our ability to recall interconnected details from minimal cues. This process, linked to sleep spindles, underscores sleep's vital function...

A study in the Journal of Sleep Research found no significant link between insomnia, emotional distress, and sleep bruxism. Using polysomnography, researchers showed that insomnia sufferers are no more likely to experience teeth grinding during sleep than those without sleep...

A study sheds light on how sleep deprivation affects emotions, dulling positive feelings more than negative ones in college students. Higher sleepiness led to less joy, highlighting sleep's crucial role in emotional health.

Researchers have demonstrated that lucid dreamers can control and respond to a virtual environment in their dreams, successfully navigating a virtual car. This study, published in the International Journal of Dream Research, marks a significant advancement in dream control technology.

Men who use muscle-boosting steroids are more likely to suffer from poor sleep quality. The findings, published in BMC Psychiatry, suggest that these sleep issues might persist even after steroid use ends.

A study in China found that parental phubbing, where parents focus on phones over interacting with their children, leads to increased sleep problems in adolescents. This effect is mediated by negative emotions, especially in those with lower self-control.

Researchers have discovered it's possible to communicate with people during various sleep stages, including REM, by receiving simple responses to questions and stimuli. This breakthrough enhances our understanding of dreams and opens new avenues for studying the sleeping brain.

A study in Neurology shows irregular sleep patterns and, to a lesser extent, overly consistent ones are linked to an increased dementia risk. Researchers emphasize the importance of balanced sleep schedules for cognitive health.

Extending sleep by one hour nightly improved college students' heart health, glucose regulation, and hydration while reducing sleepiness. This small change also led to lower blood pressure.

In a new scientific paper recently published in the journal Cell Press, researchers have unveiled new insights into how the brain processes and consolidates emotional memories during sleep. The paper, drawing on extensive rodent-based research, highlights the critical role of...

Researchers discovered that while a single dose of caffeine can improve attention in sleep-deprived individuals, regular high consumption of caffeine leads to diminished attentional performance, as well as alterations in brain activity.
