Health is a state of complete physical, mental and social well-being of a person, which ensures its high efficiency and social activity. The human body adapts to the change in the intensity of the action of environmental factors, thanks to which an equilibrium is established between it and the environment: the organism responds to changes in the activity of a certain ecological factor by changes in the processes of vital activity. Violation of this balance leads to the development of the disease.

All activities for human health are divided into curative and preventive. Treatment includes diagnosis that determines the cause of the disease, the treatment itself and rehabilitation – recovery of the body during recovery. An important component of treatment is the prevention of diseases. This is a set of measures aimed at preventing the occurrence and spread of diseases, strengthening health.
