Science behind Sleep and Immunity

When humans sleep, the immune system in their body releases Cytokines. This is a protein that is responsible for promoting sleep. The same Cytokines also multiply in number when the body is fighting with an infection or an inflammation. They also help to tackle stress.

When an individual is sleep deprived, the production of these protective proteins, Cytokines in the body decreases. Also, the antibodies and the cells in the body those are responsible for fighting an infection go down in number during the period of sleep deprivation, leaving the body highly susceptible to viruses and illnesses.

So, simply put, a healthy body needs regular and adequate sleeping hours to be able to fight infections or diseases. Several researches have shown clear co-relation between long-term lack of sleep and diseases such as Diabetes, Obesity and Cardiovascular diseases. For the same reason, these are termed as life style diseases.
