How Much Sleep Do You Really Need?
Written by clive on 12:27 PMThe amount of sleep that people needs varies tremendously. There is no normal amount. Different people need different amounts of sleep. But the amount that any one person needs is amazingly constant. Although you may sleep longer one night than another depending on circumstances, the number of hours you sleep over a week or a mouth usually averages out very much the same - one week usually falls within one-half hour of another week.
Eight hours of sleep a night is the usual quoted average, although seven to seven and a half hours is more accurate for most people. Even that number is only an average and has nothing to do with what's good or bad. A good night's sleep can range from less than three hours to more than ten.
Sleep researchers call people who sleep six hours or less short sleepers and people who sleep nine hours or more long sleepers. Some people seem to get by on very little sleep. When two sleep researchers put an ad in a newspaper asking for people who slept only a few hours each night, they found a 54 year old executive and a 30 year old draftsman who both said they slept about three hours a night. A week in the sleep lab confirmed their claims. Both said that they just didn't feel they needed more sleep.
So how much sleep you need varies from person to person,
Individuals also can have different sleep needs at different times. They may need more sleep in times of stress, during depression or grief, or during times of increased mental effort. Some women sleep more during premenstrual periods. Less sleep may be needed during times when things are going especially well for a person.
