(HuffPost) — When you're powering through a sleepless day at work, you probably don't realize just how impaired you are.
You may think you feel fine, but sleep deprivation undermines you on the job.
The Centers for Disease Control and Prevention, which recommends between seven and nine hours of sleep each night for adults, has found that 1 in 3 adults are falling short of this. In a 2016 CareerBuilder survey of 3,200 employees, 1 in 5 said they averaged five hours of sleep or less a night.
Yet many of us are unaware of the effects of sleep deprivation.
“If you got fewer than seven hours of sleep last night, you are a little bit sleep-deprived. And you will probably deny that and say, ‘No, I’m fine.’ But if we were to bring you into one of our sleep labs and have you do some performance tests, we would be able to see that you are not as good at doing those as you are fully rested,” said Jeanne Duffy, a neuroscientist and associate professor of medicine at Harvard Medical School in the Division of Sleep and Circadian Disorders.
