A study analyzing data from over 11,600 mother-child pairs found that having a child with eczema was associated with difficulty falling asleep, insufficient sleep, and increased daytime exhaustion for mothers. The severity of a child's eczema was linked to worse sleep outcomes for mothers.
Researchers found that low-risk patients undergoing total hip replacement with a posterior approach can eliminate standard hip precautions without increasing the risk of dislocation. This could lead to improved recovery and reduced fear in patients, as they focus more on mobility rather than restrictions.
A recent study has identified 76 new gene regions associated with sleep duration, revealing a significant link between genetics and sleep patterns. The findings suggest that many genes important for animal models may also influence human sleep, opening up new avenues for understanding the regulation of sleep.
A study found that napping during the day can significantly lower blood pressure levels, with an average drop of 5 mm Hg. This reduction is comparable to other known interventions for lowering blood pressure.

The American Academy of Sleep Medicine published a clinical practice guideline for the use of positive airway pressure (PAP) therapy to treat obstructive sleep apnea (OSA) in adults. The guideline provides nine recommendations, including the use of PAP therapy as a first-line treatment for OSA in adults with excessive sleepiness.

Children overestimated their sleep duration by a median of 32 minutes, while parents overestimated it by 36 minutes.
A study by University of Birmingham researchers found lower brain connectivity in 'night owls' compared to morning larks, leading to poorer attention, slower reactions and increased sleepiness. This can be particularly problematic for those forced to fit into a societal 9-5 working day that doesn't align with their natural rhythms.
A Massachusetts General Hospital study found that hypocretin, a hormone regulating wakefulness, also controls the production of inflammatory white blood cells. This discovery suggests that insufficient sleep increases the risk of cardiovascular disease by disrupting this process.

The research also suggests that tracking sleep, activity, mood, and energy levels concurrently can provide valuable insights for people with bipolar disorder.
Delaying high school start times in Seattle increased daily sleep by over half an hour and was linked to improved academic performance. The change also showed promise for reducing absenteeism and improving punctuality among economically disadvantaged students.
Researchers at the University of Washington found that delaying school start times for Seattle high schools resulted in a median increase of 34 minutes of sleep each night. This led to improved academic performance and more consistent wake-up times, with students sleeping in longer and waking up closer to their natural wake-up times.
Researchers studied 91,105 UK Biobank participants and found 14 genetic regions related to physical activity, including seven new discoveries. The analysis also showed that increased physical activity lowers blood pressure and has a causal link to better health outcomes.
Scientists review interplay between sleep and TBI to improve diagnosis and treatment of sleep disorders. Early treatment is crucial for optimal cognitive recovery, and non-pharmacologic interventions like regular bedtime routines and sleep-conducive environments can help.
Research suggests that having a regular bedtime and getting enough sleep from early childhood may lead to healthier body weight in adolescence. Children who had age-appropriate bedtimes were found to have optimal sleep patterns and lower BMI compared to those with suboptimal bedtimes.
Sleep problems are prevalent and increasing among young adult students, with women experiencing a higher prevalence of insomnia. The study suggests that sleep issues warrant attention as a public health concern in this population.
