deep sleep

On the contrary, a short, disturbed catnap offers no such mental boost, researchers from University of California, San Diego found.

Scientists have stated that dreaming helps in restoring memories, in fact, the rapid eye movement (REM) sleep, stage of sleep when one dreams, is part of the memory process, the Daily Express reported.

Good sleep harbors good imagination

Researchers from University of Montreal’s (UM) Department of Psychology, Canada found that men, as they mature, are unable to experience deep sleep and have reduced testosterone levels, and there appears to be a link between the two.

Live Science quoted study leader, Zoran Sekerovic, graduate student, UM’s Department of Psychology, as saying, “Deep sleep is when the recuperation of body and mind is optimal.”

The research initiated by Professor Jim Horne and his colleagues from the Sleep Research Centre at Loughborough University found that 18 percent of women complain of a bad night sleep at least five days in a week compared to only 8 percent men.

Professor Horne, who is the lead author of the study and also director at the Sleep Research Centre, informs, “Women need 20 minutes more shut-eye than the average man. This is because women’s brains are wired differently from men’s and are more complex, so their sleep need is slightly greater.”
