The discovery suggests that the transition to a dark environment may be associated with changes in sleep behavior, potentially due to the need for continuous vigilance to find food.
A study found that sleep deprivation leads to increased activity in brain regions assessing positive outcomes and decreased activity in those processing negative outcomes. As a result, sleep-deprived individuals are more likely to choose options with potential gains over those with potential losses.

The study suggests that prescribing practices should target younger populations to reduce long-term use
A study published in Sleep found that a woman's perception of poor sleep and its impact on daytime functioning are stronger predictors of immediate postpartum mood disturbances than actual sleep quality and quantity. Poor subjective nighttime sleep during pregnancy and after delivery is associated with worse postpartum mood.
A study found that extreme sleep duration is related to increased abdominal fat in minority young adults, particularly those with short sleep (5 hours or less) and long sleep (8 hours or more). This association was observed across genders and ethnicities.

Researchers discovered a new way to monitor sleep and potentially diagnose sleep disorders by analyzing heart rate, revealing significant relationships between cardio-respiratory synchronization patterns and sleep stages. This technique may help clinicians diagnose sleep disorders more easily and determine optimal treatments.
Research suggests that preconceptional psychological distress is a strong predictor of infant night waking, increasing the risk by 23% at 6 months and 22% at 12 months. This can lead to sleep problems in early childhood, affecting learning abilities and behavior.
A new study found that older women who reported taking daily naps had a 44% increased risk of dying from any cause. This association remained significant among relatively healthy women and was strongest for cardiovascular-related mortality.
A school-based sleep intervention improved adolescents' sleep problems, producing a high retention rate of 83% and increasing students' knowledge of sleep-related issues. However, the positive effect disappeared at the six-week follow-up.
A study suggests that childhood sleep problems persisting through adolescence can affect cognitive abilities, particularly executive functioning. Sleep problems during late childhood and early adolescence, such as being overtired or sleeping more than others, were found to be strong predictors of later executive control.
A study published in the journal Sleep found that women with restless legs syndrome (RLS) have higher levels of estradiol during pregnancy, which may contribute to the development of RLS symptoms. The study also found that women with RLS experience more periodic limb movements (PLMs) before and after delivery.
A study found that delaying school start times by one hour improved teens' average nightly sleep hours and reduced their involvement in auto accidents. This change also led to a decrease in daytime sleepiness and an increase in students getting at least eight hours of sleep per night.
A study found that high levels of prenatal smoking exposure strongly modify sleep patterns in preterm neonates, with disrupted sleep structure and fragmentation observed. This may have serious consequences for the development of the infant's brain and increase the risk of developmental difficulties throughout childhood.
A study found that night shift workers who use bright light exposure therapy, dark sunglasses, and a strict sleep schedule can achieve a compromise circadian phase position, improving alertness and performance. This partial physiological adaptation allows for increased daytime sleep on days off.
A study published in Sleep found that postmenopausal women slept longer than premenopausal women, with deeper sleep and increased total sleep time. However, the rate of change in sex hormones during menopause was also associated with poor subjective sleep quality.
Researchers at Baylor College of Medicine discovered that mice deficient in fragile X and related genes have disrupted sleep-wake cycles, leading to a lack of rhythm. This finding provides new insights into the causes of fragile X syndrome and its impact on patients.
Research reveals a correlation between the phase of clock gene expression and habitual sleep timing, suggesting a peripheral circadian clock's role in regulating hormone rhythms and sleep-wake cycles. The study's findings provide new insights into the relationship between genetic markers and sleep disorders.
A new study published in SLEEP journal found that short and long sleep durations are associated with an increased risk of metabolic syndrome. Adults who slept less than six hours per night had nearly double the odds of developing metabolic syndrome compared to those who slept between seven and eight hours per night.
A new type of anesthetic, ethyl carbamate or urethane, has been found to induce the full spectrum of natural sleep stages, including slow-wave sleep and rapid eye movement (REM) sleep. This breakthrough discovery allows researchers to fine-tune sleep medications and anesthetics, ultimately benefiting patients with sleep disorders.
Research highlights the long-term consequences of childhood sleep disorders on mental health, including emotional and behavioral changes. Experts stress the need for better recognition and treatment of sleep disorders in children to prevent future problems.
A study found that both short and long sleeping times are associated with an increased risk of future body weight and fat gain in adults. Adults who slept less than 7 hours or more than 10 hours per night gained more weight over six years compared to those who slept for 7-8 hours.
A new study found that sleep deprivation can precipitate sleepwalking in predisposed individuals and may serve as a valuable tool in diagnosing the disorder. The study showed that sleep deprivation significantly increased the proportion of sleepwalkers experiencing complex episodes, facilitating diagnosis.
A study published in SLEEP found that REM sleep deprivation in rats reduced cell proliferation by 63% compared to non-deprived controls. This suggests a critical role for REM sleep in facilitating brain plasticity and adult neurogenesis.
A study published in SLEEP found that higher periodic leg movement index (PLMI) predicted less sleep at night in older people with cognitive impairment. The study, conducted by Kathy C. Richards of the University of Pennsylvania, assessed 102 participants and found that PLMI explained 43.6% of the variance in total sleep time.
A study published in the journal SLEEP found that a brief daytime nap (45 minutes) benefits declarative memory performance. The results suggest that there is a threshold acquisition level required for sleep to optimally process memories, and this finding has implications for adults' nightly sleep recommendations.
Researchers found that dreams after 9/11 showed more intense imagery but not longer or more bizarre content, contradicting expectations. The study suggests a link between the traumatic event and increased emotional intensity in dreams.
C. elegans displays a sleep-like state called lethargus, which parallels human sleep patterns and is linked to nervous system development, suggesting that sleep facilitates neural growth and adaptation.
A study found that children who don't get enough nightly sleep are more likely to be overweight and have behavioral problems. Sleep duration was shorter on weekends, in the summer, and when bedtime was after 9:00 p.m.
