Sleeping too much and sleeping too less, both affect your health adversely. According to a new study by scientists at Warwick University, adults who sleep more than 9 hours a night are at 30 percent higher risk of dying early. In addition, people who sleep less than 6 hours a night are also likely to die early. Researchers say that people who take 7-8 hours of night sleep had higher life quality and comparatively lived longer than long sleepers and short sleepers.
The study was conducted over one million people for over a decade. Researchers recorded sleeping habits of every participant and found that excess sleeping and short sleeping both had negative impact. Also, short sleepers and long sleepers both were prone to several health related problems including depression, diabetes, cardiovascular diseases, etc.
While comparing the data it was revealed that 30 percent more long sleepers and 12 percent more short sleepers died early than the moderate sleepers within the same period of time.
Lead researcher, Prof Cappuccio said, “Seven hours sleep keeps turning up over and over again.”The typical adult today reports seven hours of sleep. And that actually seems to be the median sleep duration in the adult population around the world. That suggests there’s something around seven hours of sleep that’s kind of natural for the brain.”
The study authors warned people by saying that too much sleeping and too less sleeping both are similar to excess alcohol consumption as all the three lead to increased mortality rate.
Moreover, problem of inconsistent sleep is more pronounced among the people who work in shifts, As working in shifts creates imbalance in biological clock making it much harder to get timely sleep.
