Sleep deprivation can cause damage to the body in the short term and may lead to chronic health problems and negatively impact one’s quality of life.
Not getting enough sleep prevents the body from strengthening the immune system and producing more cytokines to fight infection.

Sleep deprivation can also result in an increased risk of new and advanced respiratory diseases.
A lack of sleep can affect body weight. Two hormones in the body, leptin and ghrelin, control feelings of hunger and satiety, or fullness. The levels of these hormones are affected by sleep. Sleep deprivation also causes the release of insulin, which leads to increased fat storage and a higher risk of type 2 diabetes. Sleep helps the heart vessels to heal and rebuild as well as affecting processes that maintain blood pressure and sugar levels as well as inflammation control. Not sleeping enough increases the risk of cardiovascular disease. Insufficient sleep can affect hormone production, including growth hormones and testosterone in men.
