Question

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 sleep over long periods of time, the less accurate you are of judging your own sleep perception,” she
said.
Multiple studies have __11__ 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 children nine to 11 hours. People’s
performance continues to be poor while they are sleep deprived, Dr. Veasey said.
Health issues like pain, sleep apnea or autoimmune disease 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
that governs our sleep-wake cycle can also drive up the need for sleep, Dr. Meredith said. The brain’s clock can
get misaligned 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 at a time of day when the body wants to be
winding down.
