Less than six hours of sleep per day can be a cause of early death, says British and Italian researchers. People experiencing persistent sleep deprivation have 12 per cent more chances to die within the next 25 years that those who sleep from 6 to 8 hours per day. This is especially important for young people.
The researchers also found a link between more than nine hours of sleep and early death as constant fatigue and a need of sleep may warn about health problems.
This is based on studies involving more than 1.5 million people. They tried to establish the relation between early death and a lack of sleep. Moreover, they were taking into consideration previous studies made in the UK and the USA as well as European and East Asia countries.
As a conclusion, the researchers stated that early death is associated both with a lack of sleep and its excess and the ideal sleep duration is 6-8 hours per day. Modern society is slowly forced to reduce hours of sleep. In this way, people risk to their health. On the other hand, excess of sleep is also not a good thing for our health. It’s rather an indicator of health problems.
