For five weeks I’ve stayed put geographically, but my circadian rhythms have marched westward, advancing two-thirds of a time zone each morning to match the 24.65-hour day of our neighbor planet.

“The witching hour, someone had once whispered to her, was a special moment in the middle of the night when every child and every grown-up was in a deep deep sleep, and all the dark things came out from hiding and had the world all to themselves.” Roald Dahl, “The BFG,” about five minutes before [...]

Driving under the influence of alcohol or drugs is known to increase the chances of causing an accident. For instance, marijuana can impair drivers’ reaction time. But what about drowsiness? As many as a third of all fatal car crashes might involve fatigued drivers, according to research by the National Highway Traffic Safety Administration. And [...]

Sleep deprivation can lead to plenty of unwise decisions, which researchers have long tied to flagging attention and short-term memory. But a new study shows how just one night of missed sleep can make people more likely to chase big gains while risking even larger losses—independent of their tapering attention spans. A team of Duke [...]

Laying up for a solid night’s sleep might not sound like the best recipe for weight loss, but loads of research has pointed to the importance of sufficient shut-eye to losing weight. And a small new study shows that not getting enough sleep might severely cut into people’s ability to lose extra fat.  Researchers found [...]
