The levels of these two hormones in the body are affected by sleep and its duration, as staying up and lack of hours of sleep leads to the body secreting the hormone insulin, which works Increase the body's storage of fat, and increase the likelihood of the body developing type 2 diabetes.

Continuing this situation will lead to long-term mood disorders in humans, which is one of the most important symptoms of depression and anxiety, as some studies conducted on people who suffer from stress indicate that they all sleep for less than six hours.

immune system

Leads ensure lack of sleep to the weakening of the immune system in humans; through lack of the body to produce more cytokines ( in English: cytokines), which works to strengthen the immune system, which means that the human body will take a longer time to recover from the infection, and will increase the chances of chronic diseases .
