Sleep more stay Slim !

Sleeping more than 8 hours a night may help you stay slim.

 

 

A new study has found that sleeping more than nine hours a night appears to suppress genetic factors that lead to weight gain.
In contrast, getting too little sleep seems to have the opposite effect.
Previous research has shown an association between poor sleep and obesity, but the new findings reveal a complex interaction between sleep and genetic factors linked to body weight.
Scientists made the discovery after studying 1088 pairs of identical and non-identical twins.
Twin studies help researchers unravel genetic and environmental influences. Only identical twins share the same genes, and are therefore subject to the same genetic effects, so differences between them are likely to be due to environmental factors.
''Evidence is mounting that chronically reduced sleep times are associated with obesity," they added.
Sleep may influence weight by affecting hormones, glucose metabolism and inflammation, they said.
Some studies have associated long sleep duration with heart disease, insulin resistence (a precursor to diabetes) and early death.
''We did not observe this in our sample, but our sample is much younger than those used in studies that established these adverse associations,'' the researchers noted.
The findings were published on Monday in the journal, Sleep.
