An observational study of nearly 44,000 women found that exposure to artificial light at night while sleeping was associated with measures of obesity at baseline and follow-up. Reducing exposure to artificial light at night could be considered in obesity prevention interventions.
A new study found that people who get less than 7 hours of sleep per night tend to consume fewer essential vitamins and minerals. The research also revealed a greater association between poor sleep and lower nutrient intake in women.
A randomized controlled trial found that telemedicine cognitive behavioral therapy for insomnia was equally effective to in-person delivery in improving sleep outcomes. Participants reported no differences in therapist alliance or satisfaction with treatment between the two groups.
Research found that participants who shifted their sleep/wake timings could bring forward their bedtime and wake-up time by two hours, leading to improvements in depression, stress, and daytime sleepiness. Participants also reported better mental well-being and increased cognitive performance during the morning.
A new study links severe sleep-disordered breathing to epigenetic age acceleration, with women showing stronger associations than men. The study found that untreated sleep-disordered breathing can accelerate aging by the equivalent of 215-321 days.

The study enrolled 302 resident physicians and used a clustered-randomized crossover clinical trial to compare two work schedules.
A study published in Sleep Health found that preschoolers who watch TV sleep significantly less than those who don't. The research suggests that TV use affects the quality and duration of sleep, and even stimulates or violent adult programming can interfere with children's ability to fall asleep.
A UC Riverside-led team found strong associations between working memory and factors like sleep quality, age, and depressed mood. The researchers discovered that each factor affects different aspects of working memory, with poor sleep quality and depressed mood linked to reduced quantitative memory.
A University at Buffalo study found that cyberbullying is linked to poor sleep quality, which can exacerbate depression in teens. Nearly 15% of high school students report being bullied online.
Chronic short sleep is linked to clogged arteries and increased mortality rates. Lowered levels of microRNA molecules are now recognized as sensitive biomarkers for cardiovascular health, inflammation, and disease.

A new study finds that women and mice experience changes in their daily schedules and activity levels during the first third of pregnancy. The study suggests that these changes may be related to hormonal influences and could have implications for preterm birth prevention.
A new quality improvement tool called Eat, Sleep and Console (ESC) has been shown to improve care of opioid-exposed newborns in NICUs. The ESC approach uses non-pharmacologic interventions and reduces hospital stays and medication exposure.
A new study found that women tend to underreport snoring and underestimate its loudness, with only 72% reporting snoring compared to 88% objective measurements. Women also reported snoring less often and described it as milder, potentially due to social stigma.
A study found that increasing physical activity can eliminate the association between sedentary behavior and increased mortality risk. Replacing sitting with standing or vigorous physical activity was more consistently associated with risk reduction in high sitters.
A new study reveals that soft bedding is responsible for almost 70% of sleep-related infant deaths. The most common causes of suffocation in babies under one year old are overlay, soft bedding, and wedging.
Researchers from the University of Surrey argue that a switch to permanent daylight saving time would undermine the sleep benefits of delaying school start times. This could lead to inadequate levels of sleep among teenagers, despite efforts to improve their health and graduation rates.
Researchers warn that permanent daylight savings time could negate benefits from delaying school start times, which aim to give teens more sleep. The study suggests that schools would need to delay start times by one hour during winter months under permanent DST.
A Canadian study of over 2,400 families found that spending two hours or more of screen time per day is associated with clinically significant behavioral problems in preschoolers. Organized sports and good quality sleep were also identified as protective factors against the negative effects of screen time.
A new study identifies 20 common sleep myths that can lead to poor habits and serious health risks. The researchers suggest creating a consistent sleep schedule and spending at least seven hours asleep to promote overall better health.
Researchers at Hiroshima University Hospital have developed an oral appliance to treat mild to moderate sleep apnea. The treatment, which brings the jawbone forward to enlarge air passageways, was found to halve sleep apnea episodes and widen airways in a study of 13 patients.
A recent study by Dr. David Munoz reveals the APOE ε4 allele affects sleep patterns differently in women and men with Alzheimer's disease. The research found carriers of this gene variant experience more nighttime disturbances than non-carriers, highlighting a gender-based effect on sleep behavior.

Researchers have identified phosphodiesterase-B1 as a critical gene for the transmission of African sleeping sickness, a disease transmitted by tsetse flies. The study reveals that the parasite's movement from the fly's midgut to the salivary gland is controlled by this gene, providing new insights into the disease-causing mechanism.
A new study published in EClinicalMedicine found that pregnant women who sleep on their backs are at a higher risk of stillbirth, with the risk increasing by 2.6 times after 28 weeks of pregnancy. The NHS has now incorporated the findings into its Saving Babies' Lives care advice information for pregnant women.
A study found that teenagers with ADHD who got less sleep experienced significant deficits in executive functioning skills, including working memory, planning, and organization. In contrast, those who got more sleep showed improved performance.
A study published in Nature Communications has found 47 links between the genetic code and sleep quality, quantity, and timing. The research team identified a gene called PDE11A as affecting not only sleep duration but also quality, with variants impacting sleep measures.

A study found that sleep quality decreases in the late luteal phase, just before menstruation, with less sleep efficiency, longer wake after sleep onset, and higher sleep fragmentation index. Caloric restriction also negatively affects sleep during this period.
A new study by The Endocrine Society found that treating obstructive sleep apnea (OSA) with an overnight CPAP machine can result in more weight loss for adults with obesity who try to lose weight by restricting calories. Patients who received concurrent CPAP treatment lost an average of 5.7 pounds more than those who did not treat thei...
