Something I need to take seriousy.
In fact, according to Roenneberg’s groundbreaking study in Current Biology, about one-third of people living in first-world countries are required to wake up two hours before their circadian clocks, or “natural waking times,” tell them to, and 69 percent of people have to wake up one hour before their bodies would like them to.
Of course, different people require different amounts of sleep and although there’s no universal rule for how long we should all be sleeping, it’s becoming increasingly clear that working late and waking early can cause serious problems. It’s not just repeated sleep deprivation that does people in, either. Just one restless night can seriously affect us in the morning.
Getting less than five hours of sleep a night makes people dumber and less able to concentrate, and it can make people more susceptible to false memories, according to a new study published in the September issue of Psychological Science.
