Sleep is a highly under-rated aspect of modern life. The jetsetters like to work hard and party harder (and sometimes just work harder!) at night. Well, this had to have an effect on the metabolism of the body and hence obesity.
We had told you recently about how a good night’s sleep can make you wake up with a positive attitude. Now, according to studies by Dr Kristen Knutson from the University of Chicago, there is a definite association between sleeping less than six hours and increased obesity or body mass index (BMI).
This is how it works:
Inadequate sleep leads to secretion of a hormone called ghrelin which increases appetite. Haven’t you binged at times in the morning after tossing and turning on the bed all night? Or when you stayed up all night during an exam?
The study also found that this holds true more so in case of children and adolescents, and in people from a lower socio-economic status.
The increasec chances of obesity of course leads to a higher risk of diseases like diabetes, high blood pressure and heart disease.
The study has been published in The American Journal of Human Biology.
