The researchers came to the conclusion that lack of sleep can undermine your immune system. This discovery shows that lack of sleep has the same harmful effects on the body as physical stress.
For the study, researchers measured the number of white blood cells of 15 healthy men and women, at the time, as they were deprived of normal sleep and sleep under normal conditions.
White blood cells, known as leukocytes, protect the body from disease by developing antibodies. There are five types of white blood cells.
In particular, the researchers found that the increase in the number of granulocytes, and loss of rhythm of cells that surround and destroy bacteria appearing in the blood. Granulocytes are the most numerous white blood cells in the human body.
Blood samples for the study were collected during the normal sleep cycle. They are then compared with the number of granulocytes, which have been developed during 29 hours of wakefulness.
According to doctors, granulocytes react immediately on the stress state of the organism due to lack or absence of sleep and directly reflect the stress response of the body.
Immunity and sleep
An expert from the Mayo clinic, doctor of medical Sciences Timothy Morgenthaler explained why sleep is so crucial in the fight against the disease. The fact that during sleep produced proteins (known as cytokines) that fight infection.
However, excess sleep causes various health problems including obesity, heart disease and depression. Adults should sleep 7-8 hours in order to be healthy.
“Future research will reveal the molecular mechanism responsible for the immediate response to stress, and find out his role in the development of diseases associated with chronic sleep deprivation,” – said in a press release Katrin Ackermann, Ph. D. and lead author of the study.
Lack of sleep affects the immune system as physical stress is a proven study. Lack of sleep activates the immune system, causing white blood cells to go up and lose a cyclical rhythm of work.
Long-lasting effect caused by sleep deprivation, can contribute to the development of various diseases.
