Sleep deprivation affects us much more than prior theories have suggested, one of the largest sleep studies to date reveals[1]. “Our research showed that sleep deprivation doubles the odds of making placekeeping errors and triples the number of lapses in attention, which is startling. Sleep-deprived individuals need to exercise caution in absolutely everything that they… Read more

Teens got 43 more minutes of sleep a night after a four-week intervention that reset their body clocks and helped them go to bed earlier, Stanford researchers report[1]. The treatment had two components: brief, early morning flashes of bright, broad-spectrum white light to reset the teens’ circadian clocks, and cognitive behavioral therapy that motivated them… Read more

Rapid eye movement, or REM, sleep is when most of our dreams are made. Now, in a study of mice, a team of Japanese and U.S. researchers show that it may also be a time when the brain actively forgets[1]. Forgetting during sleep, their results indicate, that may be controlled by neurons found deep inside… Read more

The intensity of brain activity during the day, regardless of how long we’ve been awake, appears to escalate our requirements for sleep, according to a new University College London study in zebrafish. The research found a gene that responds to brain activity in order to coordinate the need for sleep. It helps shed new light… Read more

A mother and daughter who share a rare genetic mutation and who routinely need just six hours of sleep a night have led to researchers taking a further step in untangling the genetic web of sleep[1]. “Before we identified the first short-sleep gene, people really weren’t thinking about sleep duration in genetic terms,” said Ying-Hui… Read more
