The American Heart Association study found that if you get less than six hours of sleep per night, the presence of heart disease and people with risk factors for diabetes are twice as likely to have a heart attack or stroke as the general population. Adolescents who suffer from chronic insomnia are much more likely to grow up with hyperlipidemia.

Digestive system

In addition to over-eating and inactivity, sleep deprivation is a major factor in overweight and obesity. Sleep affects the levels of two hormones in the body: leptin and growth hormone-releasing peptide, which control feelings of hunger and fullness. Leptin tells the brain that you’re full.

Chronic lack of sleep can also increase your risk of developing chronic diseases like diabetes and heart disease.

In turn, sleep deprivation can worsen existing respiratory conditions, such as chronic lung disease and more.
