Beat obesity with better sleep


Sleep deprivation is one of the main causes of obesity and overweight. Several studies show that people sleep less than eight hours a day have more chances of putting on weight. So, having a better sleep is a way of beating obesity and overweight.

The relationship between sleep and obesity: 


Many population studies show that lack of sleep is associated with increased weight gain. This finding is supported by laboratory researches. Scientists found that inadequate sleep causes an imbalance between two hormones in the body. These hormones play an important role in regulating our appetite. Lack of sleep result in high levels of hormone called ghrelin. This hormone stimulates appetite and makes us to eat more food. In addition, sleep deprivation lowers the levels of appetite-suppressing hormone leptin.


Obese people tend to have obstructive sleep apnea. In this condition, breathing stops for many seconds, hundreds of times during sleep. This leads to frequent waking at night and poor quality sleep. This in turn can cause weight gain. This is a vicious cycle relationship between lack of sleep and obesity.
