Participants wore wrap-around frames with amber or clear lenses for seven consecutive nights, resulting in an average of 30 minutes extra sleep and improved insomnia severity.
Scientists have identified 126 genetic differences among 80 genes associated with sleep duration in fruit fly populations. These findings may lead to better treatments for insomnia and narcolepsy, with little physiological consequence for extreme long or short sleepers.
Researchers identified 126 genetic variations in wild fruit flies that affect sleep duration, with some individuals needing more or less sleep than others. The study suggests that multiple signaling pathways contribute to sleep duration and may explain why a single purpose for sleep has been difficult to pin down.
After retiring from work life, people sleep approximately 20 minutes longer than before retirement and experience improved sleep quality. This is particularly true for individuals who had previously experienced sleep difficulties or were heavy alcohol users, with a notable decrease in early morning awakenings and nonrestorative sleep.

A new study found that positive airway pressure therapy significantly improves both general and sleep-specific quality of life measures in patients with obstructive sleep apnea. The improvements were most notable in those who adhered to the treatment.
Researchers at the University of York found that sleep helps us use our memory in a flexible and adaptable manner by strengthening both old and new versions of an experience. This process allows for the adaptive updating of memories, but can also lead to distortions if incorrect information is incorporated.
Research finds a link between insomnia and frequency of alcohol use among seventh- and eighth-grade students. Insomnia is identified as a risk marker for alcohol use, while symptoms of mental health problems and parental monitoring do not account for the association.
A study of 90 adults with type 2 diabetes found female gender, elevated blood sugar levels, neuropathic pain, and fatigue to be linked to sleep disturbance. Clinicians should prioritize females in sleep-related assessments and include symptoms like pain and fatigue in comprehensive evaluations.
A review of over five dozen studies reveals that excessive screen time in youths aged 5-17 is associated with delayed bedtimes, fewer hours of sleep and poorer sleep quality. Biological, neurological and environmental factors contribute to the negative impact of digital media on sleep patterns.

The study also showed a gene-activity interaction between physical activity levels and genetic variants associated with obesity.
A new study by San Diego State University finds that adolescents are sleeping fewer hours per night than older generations, with 40% of teenagers in 2015 sleeping less than 7 hours a night. Young people's increased smartphone use is linked to decreased sleep, with teens who spend more time online being more likely to not get enough sleep.

A new poll finds that nearly half of older Americans struggle with sleep, but many don't discuss it with their doctors. Prescription sleep medications carry significant health risks for older people, and non-medication-based habits are a more effective solution.
A new fatigue cost calculator reveals that US employers can lose up to $1.4 million annually due to employee sleep deficiency. The calculator estimates costs for absenteeism, productivity loss, healthcare expenses, accidents, and other occupational costs associated with exhausted employees.
Researchers observed reduced pulsing activity at night and delayed responses to stimulation in the upside-down jellyfish Cassiopea. The findings suggest that jellyfish do indeed sleep, but the study also raises more questions about the origin of sleep and its relationship with neural systems.
A new study reveals that preterm children have more medical sleep problems, such as restlessness and breathing issues, compared to full-term children. However, they are more likely to fall asleep on their own without assistance.
Participating in twice-weekly Tibetan yoga reduced sleep disturbances and improved sleep quality in breast cancer patients undergoing chemotherapy. Women who practiced at least two times a week reported better sleep quality and efficiency over time compared to those practicing less often.
