The research revealed that constant availability and response expectations on social media accounts negatively impact sleep quality, self-esteem, and emotional well-being amo...
Researchers developed an Android sleep monitoring app widget, SleepTight, that boosted daily sleep diary information entry and self-reflection among users. The widget's visual reminders and lock screen placement increased user interaction with the data, leading to better understanding of sleep patterns and behavior.
The Phase I study confirms the therapeutic dose and safety profile of SCYX-7158, a first oral drug candidate specifically developed to combat human African trypanosomiasis. The study results translate into prolonged exposure with just one dose, targeting the late stage of the disease where the parasite crosses the blood-brain barrier.

The study highlights the importance of addressing sleep issues in individuals with hoarding behaviors to mitigate cognitive and mental health risks.
A recent study found that poor sleep quality is negatively associated with resilience among veterans and active duty service members. The study, published by the American Academy of Sleep Medicine, suggests that appraisal of sleep quality may contribute more to resilience scores than self-reported sleep efficiency.
Cognitive behavior therapy (CBT) is an evidence-based treatment for chronic insomnia that addresses the underlying causes of insomnia. Studies have shown that CBT improves sleep quality by reducing time spent awake after falling asleep, increasing sleep efficiency, and helping patients enter REM sleep faster.
A new study found that severe restless legs syndrome (RLS) is associated with a higher risk of stroke. The research, published in SLEEP, suggests that RLS severity may be considered an early risk factor for stroke, warranting modifications in clinical management.
A recent study published in SLEEP found that children with traumatic brain injuries (TBI) have impaired emotional, physical, and social functioning due to poorer sleep quality. The study also revealed that children with TBI experience greater daytime sleepiness compared to healthy children.
A new study links lower life satisfaction to sleep problems during midlife, finding that shorter sleep onset latency is associated with higher life satisfaction. The research suggests that improving one variable, such as sleep quality, may have a positive impact on another, like life satisfaction.
A new study found that infants who can resettle themselves after waking up are more likely to sleep for prolonged periods at night. By three months of age, most infants develop this ability, which is associated with longer sleep durations and reduced crying at night.
A new study found that patients with knee osteoarthritis who have poor sleep habits display greater central sensitization, an amplification of clinical pain. Catastrophizing thoughts about pain also contribute to increased central sensitization and greater clinical pain in OA patients.
A new study from the University of Pennsylvania found that specific types of physical activity are associated with better sleep habits. These include aerobics/calisthenics, biking, gardening, golfing, running, weight-lifting, and yoga/Pilates. In contrast, household and childcare work were linked to insufficient sleep.
A study published in Functional Ecology found that late-rising songbirds are more susceptible to being cuckolded, meaning they raise offspring fathered by other males. This suggests a potential role for sexual selection in shaping circadian traits in wild vertebrates.
A new study suggests that disrupted sleep can affect eating habits and behaviors, leading to increased food intake and long-term chronic health damage. The research highlights the importance of considering sleep patterns in efforts to modify dietary behavior and prevent conditions like obesity, diabetes, and heart disease.
A new study suggests that sleep can modify deeply rooted attitudes, including prejudices of race and gender. By reactivating previously learned associations during slumber, researchers found a reduction in implicit social biases after waking and one week later.
Researchers at Northwestern University discovered that a sleep-based intervention after training can significantly reduce implicit social biases. The study, published in Science, found that participants who received the intervention showed stronger bias reduction one week later. The findings challenge traditional views on habit learnin...

A new IU study identifies the 'sleeping beauties,' research papers that lie dormant for years before experiencing sudden recognition. The study found that papers in physics, chemistry, and multidisciplinary science were most likely to experience delayed citations, with some papers staying dormant for over 70 years.
A workplace intervention designed to reduce work-family conflict and increase schedule flexibility has a positive influence on the sleep patterns of employees' children. Children whose parents participated in the STAR intervention showed improved sleep quality compared to those in a control group, according to researchers at Penn State.
A UK birth cohort study found a significant association between childhood nightmares and psychotic experiences in adolescence. Researchers suggest that specific parasomnias could be an early warning sign for psychotic disorder.

A multinational study found that children with a consistent bedtime routine had better sleep outcomes, including earlier bedtimes and increased sleep duration. The positive impact of bedtime routines on sleep increases with consistency and age, making it a simple yet effective step for families to improve their child's sleep.
Researchers found obesity and depression to be underlying causes of regular drowsiness, with low-grade chronic inflammation a primary mechanism for fatigue in obese individuals. Depressed individuals also experienced high incidence of EDS, likely due to physiologic sleep disturbances.
