A NASA-funded study is investigating the effects of reduced sleep on astronauts in space, with a focus on finding optimal combinations of anchor sleep and daily naps. The research aims to mitigate cognitive impairments, improve reaction times, and enhance overall well-being among space travelers.
Researchers from the University of Pennsylvania have identified a gene called CREB that plays a role in regulating rest's rejuvenating effects. The study found that CREB activity is inversely related to the physiological urge for sleep and that blocking this activity increases the need for sleep after a period of wakefulness.
Research in Occupational and Environmental Medicine shows that prolonged wakefulness impairs reaction times, accuracy, coordination, and attention span, similar to levels of alcohol intoxication. The effects are thought to be cumulative and pose a serious risk to safety, particularly in transportation settings.
A study published in Occupational and Environmental Medicine found that prolonged wakefulness impairs cognitive performance similarly to moderate alcohol consumption. The researchers tested 39 adults who worked in transportation, finding reaction times slowed by up to 50% after 17-19 hours of waking.
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.
Insomnia is a prevalent and serious condition that can have serious consequences. Effective treatments include identifying underlying causes, such as lifestyle habits, medical conditions, or medications, and adopting good sleep hygiene practices, like restricting bedtime, avoiding naps, and increasing exercise.
Researchers found that fruit flies exhibit behavioral and molecular changes similar to those observed in mammals, suggesting they may be capable of sleeping. The study provides new insights into the functions of sleep and could lead to the development of new treatments for human sleep disorders.
A study using fMRI scans found that sleep-deprived subjects displayed increased activity in the prefrontal cortex, while verbal learning tasks activated the parietal lobes, which showed better memory performance. The brain's compensation for sleep deprivation varies depending on the cognitive task.
Researchers found that patients with more extreme daily mood swings experienced greater improvements in therapy outcomes, regardless of treatment type. This suggests that increasing patient sensitivity to stimuli may be a more effective approach than finding the best therapy for each individual.
Researchers found that chronic sleep deprivation can lead to changes in glucose tolerance and hormone secretion, resembling the effects of advanced age or early stages of diabetes. Sleep deprivation also altered thyroid-stimulating hormone production and cortisol levels, with significant consequences for overall health.
Researchers found that a single night of disrupted sleep increases levels of interleukin-6, leading to daytime fatigue and decreased well-being. Healthy young men with normal sleep patterns experienced increased IL-6 secretion during the day after missing a night of sleep.
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.
The Narcolepsy Network is launching a nationwide initiative to raise awareness about narcolepsy, a chronic neurological sleep disorder that affects an estimated 125,000 Americans. The 'Wake Up to Narcolepsy' program aims to educate people with the condition and their physicians about symptoms, diagnosis, and treatment options, helping ...
Researchers identified two critical periods of high error rates: before dawn and mid-afternoon. By understanding these patterns, workplaces can design jobs that exploit human strengths while protecting against attentional lapses caused by sleep deprivation.
Researchers investigate melatonin's potential to alleviate insomnia in patients with depression undergoing antidepressant treatment. The study aims to determine the optimal dose of melatonin to restore normal sleep patterns.
A new study reveals that hospital noise significantly disrupts the sleep of elderly patients in critical care units. The research found a strong correlation between peak sound levels and sleep arousals, with many patients spending hours awake at night.
