Many people think they can teach themselves to need less sleep, but they’re wrong, said Dr. Sigrid Veasey, a professor at the Center for Sleep and Circadian Neurobiology at the University of Pennsylvania’s Perelman School of Medicine. We might feel that we’re getting by fine on less sleep, but we’re deluding ourselves , Dr. Veasey said, largely because lack of sleep skews our self-awareness. “The more you deprive yourself of sleepover long periods of time, the less accurate you are of judging your own sleep perception,” she said.
Multiple studies have shown that people don’t functionally adapt to less sleep than their bodies need.There is a range of normal sleep times, with  most healthy adults naturally needing seven to nine hours of sleep per night, according to the National Sleep Foundation. Those over 65 need about seven to eight hours, on average, while teenagers need eight to 10 hours, and school-age childrennine to 11 hours . People’s performance continues to bepoor while  they are sleep deprived, Dr. Veasey said.
Health issues like pain, sleep apnea or autoimmunedisease can increase  people’s need for sleep, said Andrea Meredith, a neuroscientist  at the University of Maryland School of Medicine. A misalignment of the clock thatgoverns our sleep-wake cycle can  also drive up the needfor sleep, Dr.  Meredith said. The brain’s clock can getmisaligned by being  stimulated at the wrong time of day, she said, such as from caffeine in the afternoon or evening,digital screen use too close  to bedtime, or even exercise ata time of day when  the body wantsto be winding  down.
