How to rebuild internal biorhythms after a flight?

A group of American and Israeli scientists, as a result of experiments on mice, discovered the dependence of the body’s internal biorhythms on the diet. Researchers at Harvard Medical School and the Israel Medical Center have shown that the body’s internal clock can be effectively influenced by changing meal times.

Initially, the biological clock of the body is under the influence of a special group of brain cells. They, receiving information from the senses (primarily from the organs of vision about the time of day), transmit it to the centers of the brain that are responsible for sleep and wakefulness.

But the availability of food also has an impact on this system. If food is equally available both day and night, then biorhythms adjust to the change of time of day. But in some animals, food is more available at night. This becomes the reason for the restructuring of biorhythms in order to stay awake at night.

Experts believe that a similar dependence exists in humans. For example, a businessman from the USA to Japan takes 11 hours to fly, and it takes about a week for the body to adjust to the time difference and rearrange biorhythms. But if he has to fly back after 5 days, then a big load falls on the body. The state of health worsens, brain activity slows down, labor productivity decreases.

To help in this situation, according to scientists, fasting can. Lack of food for 16 hours can accelerate the restructuring of biorhythms and quickly go through the process of adaptation to a new time zone.
