# Poor Sleep Is a Major Risk Factor for Weight Gain and Obesity
A Huge review found that short sleep duration increased the chances of obesity by 89% in children and 55% in adults. That’s just in people averaging around 5h of sleep per night and its scaleable, the further you get from optimum levels of sleep the more likely you are to gain weight.
