The UK's sleep disorder services are severely lacking, with high rates of obstructive sleep apnea (OSA) in certain regions going undiagnosed and untreated. Despite the rising demand due to an aging population, many areas have limited access to specialized care, leading to a concerning mismatch between need and supply.
Researchers at Tel Aviv University found that viral respiratory infections may be behind the seasonal spike in sleep-disordered breathing among children. The study, published in Sleep Medicine, suggests that winter months are when pediatric sleep-disordered breathing worsens, contrary to previous assumptions about asthma and allergies.
Researchers found significant improvements in facial appearance, including reduced puffiness and redness, after just a few months of CPAP treatment for middle-aged patients with sleep apnea. The study used face mapping and photogrammetry techniques to measure changes in facial contours.
A new study suggests that continuous positive airway pressure (CPAP) therapy can improve the subjective impression of people with obstructive sleep apnea (OSA), making them appear more alert, youthful, and attractive. The study used digital photos to assess facial changes before and after at least two months of CPAP treatment.
A new study from Harvard School of Public Health found that blacks are more likely to sleep less than seven hours a night, increasing their risk of obesity, high blood pressure, diabetes, heart disease, and death. Black professionals had the highest prevalence of short sleep, while white professionals had the lowest.

The treatment, applied for 15 days, showed significant improvements in physical functioning and social functioning, as well as a decrease in depression scores.
New Northwestern University research shows that aerobic exercise during the day does not result in improved sleep that same night for people with existing sleep problems. Regular exercise is a healthier way to address underlying insomnia issues, as it can lead to better sleep quality and reduced fatigue over time.

Truck drivers also face challenges such as federal regulations limiting their driving hours and pressure to meet market demands, which can lead to fatigue and health issues.
A CU-Boulder study found that spending just one week in natural light while camping synchronizes the circadian clocks of participants with the timing of sunrise and sunset. Exposure to electrical lighting has disrupted our internal clocks, but natural light helps restore synchronization.
A week of camping exposed people to true dawn and dusk, synchronizing their internal biological clocks. This shift helped people revert to an early bird's schedule, with a typical modern environment causing a two-hour delay in circadian timing.
A study published in the American Journal of Human Genetics found new genetic variants that protect against human African trypanosomiasis, or sleeping sickness, also increase the risk of developing chronic kidney disease. These variants were most common in Fulani pastoralist groups living in western and central Africa.
A recent study published in Current Biology found that lunar cycles affect human sleep quality. The research revealed a significant drop in brain activity related to deep sleep around full moon, with participants also reporting poorer sleep quality and lower melatonin levels.
Research suggests that humans still respond to lunar cycles, influencing sleep patterns even when unaware of the moon phase. Studies show decreased deep sleep, slower sleep onset, and lower melatonin levels around full moon.

A study found that healthy adults with late bedtimes and chronic sleep restriction gained more weight than control subjects, likely due to increased caloric intake and fat consumption during late-night hours. The study also revealed gender and race differences in weight gain among sleep-restricted subjects.
Researchers found SAD participants have misconceptions about sleep habits similar to those of insomniacs, leading to incorrect reports of sleep duration. Cognitive behavioral therapy for insomnia may be effective in treating seasonal affective disorder by addressing unhelpful beliefs about sleep.
A virtual skin model developed by researchers at the University of Sheffield and PÎG has revealed that skin has 'sleeping' stem cells which can be woken up to regenerate skin, explaining why our ability to do so reduces with age. The model has implications for combating aging effects and skin cancer.

A study by LA BioMed found that men who get more sleep on the weekend can improve their insulin sensitivity, reducing their risk of developing type 2 diabetes. The research, conducted over six months, involved 19 non-diabetic men who slept an average of 6.2 hours per night during the week and caught up on sleep on weekends.
A study found that patients taking tasimelteon had a significantly higher rate of re-synchronization of their body clock, leading to improved night-time sleep and reduced daytime drowsiness. The medication addresses the root cause of Non-24 Hour Sleep-Wake Disorder in blind individuals by synchronizing their circadian clock.
A study found that insufficient sleep raises levels of a substance in the body that controls pleasurable eating, leading to increased hunger and appetite. The research suggests that this may be due to an elevation in the endocannabinoid molecule 2-arachidonoylglycerol, which is involved in signaling rewarding events and enjoyment of food.

A new study found that people with narcolepsy have a large increase in the number of neurons producing histamine, which may contribute to symptoms like preserved consciousness during cataplexy and fragmented nighttime sleep. This discovery suggests that drugs reducing histamine signaling at night may improve sleep in narcolepsy.
Symptoms of post-traumatic stress disorder (PTSD) following a heart attack are relatively common and associated with poor sleep quality. The study found that survivors with PTSD have a doubled risk of having another cardiac event or dying within one to three years.

The treatment also shows changes in brain activation during cognitive tasks, suggesting potential improvements in brain function.
Two studies found that fatigue affects strike-zone judgment in MLB players and can predict their career longevity. A significant relationship was also discovered between a player's sleepiness score on the Epworth Sleepiness Scale and their likelihood of remaining in the league three seasons later.
A study reveals that insomnia can impair emotion regulation by causing increased activity in the amygdala, a key player in emotional processing. This dysfunction may contribute to the development of depression.
A new study suggests that disturbed sleep in adolescents is associated with more symptoms of depression. However, perceived support and acceptance from parents and teachers appear to have a protective effect on sleep disruptions and depressive symptoms. Support from peers does not offer the same benefits.
A new study published in the New England Journal of Medicine found that tonsil/adenoid surgery improved behavior, quality of life, and other symptoms in children with obstructive sleep apnea. However, there was no significant difference seen in attention and executive function between the treatment groups.
