What is hygiene? How did it come about? What are her tasks?

A science that studies the influence of the environment on the health of an individual and the entire population and develops hygiene standards, requirements and rules for maintaining health, high working capacity and prolonging active longevity is called hygiene.
Hygiene originates from very ancient times. For the first time, the Greek physician Hippocrates, the founder of scientific medicine, drew attention to hygiene problems. In his widely known works “On a healthy lifestyle”, “On air, waters and localities”, “Instructions”, he expressed the idea of ​​the effect of air, water, soil, climate of populated areas on human health. However, many centuries passed before hygiene took shape in real science. Scientific hygiene has been developing since the second half of the 19th century.
Hygiene performs the tasks of studying the sanitary state of the environment and its impact on the human body. To solve these problems, hygiene uses physical, chemical, physiological, toxicological and some other methods.
