And the gap is not just a moonier one but that of a huge ten per cent. Not only this, those who sleep late or remain awake during the night are at a much higher risk of catching diseases such as diabetes, neurological disorders, respiratory disorders and other psychological problems. 

The research published in the journal Chronobiology International, had more than 4 lakh people as subjects. While the research does not explain as to what exactly causes the increased vulnerability to diseases or what leads to the higher mortality rate, but health experts have for long been warning against severe health issues arising out of the mismatch between our natural body clock and the body clock that we try to impose on our bodies. And this mismatch has been linked to various health issues. But in terms of linking it to mortality, this is the first of its kind study that has done so.  

The research also says that a certain part of one's body clock is genetic so it could be beyond one's control as well. But the fact that night owls have a risk of dying sooner needs to be taken more seriously as it is a public health issue.
