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.
