A study found that preschoolers' nightmares are trait-like in nature and linked to personality characteristics, as early as five months. The study also showed that children with consistent bad dreams were more anxious and emotionally disturbed at younger ages.
Research suggests that maintaining consistent sleep schedules and regular physical activity can help balance the circadian system and reduce symptoms of bipolar disorder. Studies found that patients who participated in interpersonal and social rhythm therapy experienced longer periods without new episodes of mania or depression.
A randomized study found that napping is a more efficient countermeasure to sleepiness in young people compared to middle-aged individuals. Young participants who napped slept more and had more delta sleep than their middle-aged counterparts.
A study found that hospital staff nurses who work extended hours, struggle to stay awake at work, or obtain less sleep are more likely to experience a drowsy driving episode. The risk increases with longer shift durations and is particularly high for night shifts.
A study found that both short and long sleep durations are associated with an elevated risk of mortality. Participants who slept five to six hours or less at baseline but reported extended sleep hours had lower mortality rates, while those sleeping seven to eight hours had higher mortality rates.
A five-year longitudinal observational cohort study found that anxiety is strongly associated with sleep disturbances. Those who experience severe life events are more likely to develop sleep disturbances, especially if they already have a predisposition to anxiety.

A study published in SLEEP found that adolescents who used their cell phones after bedtime were more likely to experience tiredness the next day. The researchers, led by Jan Van den Bulck, discovered that frequent phone use increased the risk of tiredness, with those using their phones daily being up to 5 times more likely to feel tired.
A recent study published in SLEEP found that rotating shift workers have significantly lower levels of serotonin compared to day workers. This could have implications for the treatment of associated comorbidities and behavioral problems in rotating shift workers.

Brain imaging revealed selectively more active anticipation of reward in the nucleus accumbens, while attenuated response to losses in the insula.
A study by Roseanna Armitage found that chronic fatigue syndrome (CFS) is associated with reduced slow wave sleep and impaired sleep drive, even after a regular night's sleep. After a four-hour sleep delay, CFS individuals exhibited significantly less slow wave activity than healthy twins.
Researchers found that BiP levels increase after prolonged wakefulness and decline during recovery sleep, affecting the need for additional rest. The study suggests that protective mechanisms against cellular stress may be attenuated after sleep deprivation, requiring animals to sleep more to recover.

The study involved 40 veterans with PTSD, who showed a 71% improvement rate compared to those receiving placebo.
A study published by the American Academy of Sleep Medicine found that men who consume more alcohol have a higher risk of sleep-related breathing disorders. For each additional drink per day, the risk increases by 25%. The study suggests that men should avoid drinking before bedtime to minimize the risk.
A study found that a generic drug called prazosin improves sleep quality and reduces trauma nightmares in veterans with posttraumatic stress disorder (PTSD). The drug, already used for high blood pressure and prostate problems, was shown to improve overall well-being and functioning.

The center aims to develop new models and databases for biomedical researchers worldwide, as well as advance understanding of genetic mechanisms underlying healthy function and diseases.
A new study published in Developmental Psychology found that older preteen children (6th grade) are at risk of chronic partial sleep deprivation, leading to increased daytime sleepiness. Family stress, parental education, and age may contribute to this issue, highlighting the need for better sleep habits and support.
A new study reveals that sleep disruption is a primary reason older adults with arthritis seek medical care, outweighing other symptoms like reduced mobility. The research suggests addressing sleep issues can be crucial in managing arthritis, particularly for those who may not connect their pain with sleep disruptions.
Researchers found that drivers involved in sleep-related crashes were four to five times more likely to work night-shift jobs and had built up 'sleep debt' or gotten far too little sleep before driving. These drivers often relied on ineffective tactics like opening windows or turning up the radio, and put themselves and others at risk ...
A study of 11 young men found that sleep debt increased glucose concentrations in the blood, while altering cortisol levels and thyroid hormone regulation. The research suggests that persistent sleep debt may exacerbate age-related chronic disorders.
A team of researchers has identified a single gene that causes familial advanced sleep phase syndrome (FASPS), a rare sleep disorder. The study found that the disorder follows a simple Mendelian inheritance pattern, making it easier to find the responsible gene and potentially leading to new treatments for circadian rhythm disorders.
Research highlights the importance of sleep in managing childhood chronic pain, including its effects on physical health and mental well-being. Behavioral treatments such as relaxation techniques and distraction methods can also help improve children's sleep and reduce pain symptoms.
A recent study found that the prevalence of U.S. infants being placed to sleep on their stomachs has dropped by 66% since 1992, resulting in a 38% decrease in SIDS deaths. Despite this progress, Black infants remain at higher risk for prone sleeping and associated SIDS deaths.
