1. We’re told to get our eight hours
We often hear that we should all be get eight hours’ sleep a night. Organisations from the NHS to the US National Sleep Foundation recommend it. But where does this advice “re coming out”?
Studies carried out of all the countries, looking at how often diseases occur in different groups of people across a population, have come to the same opinion: both short sleepers and long sleepers are more likely to have a range of sickness, and to live shorter lives.
But it’s hard to tell whether it is short sleep that is causing illnes or whether it is a symptom of a little healthful life-style.
Short sleepers are generally defined as those who regularly get less than six hours’ sleep and long sleepers generally more than nine or 10 hours’ a night.
Pre-puberty, progenies are recommended to get as much as 11 hours’ sleep a darknes, however, and up to 18 hours a day for newborn babes. Teenagers should sleep for up to 10 hours a light.
