Is Getting Eight Hours Just a Myth?
April 30, 2007
An article in BBC News Magazine is suggesting that the necessity of getting at least eight hours of sleep a night could be a fallacy.
“It’s nonsense. It’s like saying everybody should have size eight shoes, or be five foot eight inches,” said Prof Jim Horne of Loughborough University’s Sleep Research Center. “There is a normal distribution - the average sleep length is seven, seven and a quarter hours.”
Lots of people report having more or less than the average, Horne said, explaining that it may all depend on genes and what people are just used to.
The US National Sleep Foundation suggests seven to nine hours a night is advisable for adults, and a survey it conducted in 2002 suggested three-quarters of Americans had problems sleeping and a third were so sleepy during the day their activities were affected.
“In the past century, we have reduced our average time in sleep. Though our society has changed, our brains and bodies have not. Sleep deprivation is affecting us all and we are paying the price,” the organization maintains.
Prof. Horne, however, rebuts that “the test of insufficient sleep is whether you are sleepy in the day or if you remain alert through most of the day.” If you sleep for eight hours a night, go to work, and find yourself yawning regularly and drooling on the keyboard, you aren’t getting enough sleep. If you’re sleeping five hours and are operating alertly at normal or high levels, you probably are getting enough sleep. Makes sense to me.
So exactly where did the 8 hour mark come from? Prof. Horne explains that a classic demand of the 19th Century labour movement was “Eight hours labour, Eight hours recreation, Eight hours rest.” A little outdated, no?
