At the present stage of the development of science and technology, a person has the opportunity to travel long distances in a fairly short time, for example, by air travel. At the same time, many people have sleep disturbances and other vital processes. Explain the reason for these phenomena.

There are some health problems associated with flying. This is especially true for long flights. When a person falls into a different time zone, then his biological clock gets lost.
