This raises complex questions about police interrogation practices and the use of sleep deprivation in interrogations.
A study found that two consecutive nights of extended sleep can counteract the increased risk of diabetes associated with short-term sleep restriction during the work week. Insulin sensitivity and diabetes risk returned to normal after two nights of extended sleep.
A Johns Hopkins surgeon calls on hospitals to end preventable bouts of food and sleep deprivation in emergency rooms and surgical units. The expert argues that acute malnutrition and sleep deprivation have increased with busier hospitals and an aging population, leading to delayed healing and readmissions.
A new study finds that high school students lose an average of 32 minutes of sleep per night following the springtime change to daylight saving time. This leads to increased daytime sleepiness and decreased vigilance, posing a risk to teen drivers. The study suggests that this can further restrict their already limited sleep schedules.
