Bad news for the “Kumvokornos”

As we all know, the Bengali word "Kumvokorno" means "people who sleeps longer hours". While these people are enjoying many happy hours in bed – sleeping and dreaming, the researchers from University of Cambridge discovered a new association between longer hours of sleeping and stroke!

Yes, sleeping more than eight hours in a day increases the stroke risk. 

A recently published study in "Neurology" journal revealed the relationship between sleep duration over time and subsequent risk of stroke.

However those who slept for less than six hours were also in danger, with their risk rising by 18 per cent, suggesting that there is an optimal amount of rest needed for good health. Longer sleep duration affects the older people more adversely as the results suggests.

So, the researchers indicated further research to be done to understand the causal pathways of longer duration of sleep and stroke.

While the scientists are looking for more evidences and trying to establish causal pathways, do not oversleep yourself to be on the safe side!
