Hwever, it’s clear that the less we sleep, the wrse we perfrm in everyday life. Have yu ever felt tired in the middle f the day, especially after lunch? Actually, this is quite nrmal. Researchers have fund that it may be healthier t sleep twice a day—a lng sleep at night, and a nap in the afternn. Even a ten-minute nap at lunchtime can allw us t wrk better in the afternn.

Jim Steed, a sleep researcher, has a simpler way f lking at it. “Frget abut facts and figures. If we feel tired in the daytime, it means we need t get mre sleep. ”
