ANATOMY

Detailed explanation-1: -During sleep, your immune system releases proteins called cytokines, some of which help promote sleep. Certain cytokines need to increase when you have an infection or inflammation, or when you’re under stress. Sleep deprivation may decrease production of these protective cytokines.

Detailed explanation-2: -In fact, sleep contributes to both innate and adaptive immunity. Researchers have found that during nightly sleep, certain components of the immune system rev up. For example, there is an increased production of cytokines associated with inflammation.

Detailed explanation-3: -Cytokines are small proteins that are crucial in controlling the growth and activity of other immune system cells and blood cells. When released, they signal the immune system to do its job. Cytokines affect the growth of all blood cells and other cells that help the body’s immune and inflammation responses.

Detailed explanation-4: -Melatonin, released by the pineal gland, controls your sleep patterns. Levels increase at night time, making you feel sleepy. While you’re sleeping, your pituitary gland releases growth hormone, which helps your body to grow and repair itself.
