Why is working a night shift harmful to your health?

The rhythm of life of the creatures inhabiting the Earth is biologically tied to the earthly routine: the change of climates, the change of day and night. The human body is a part of nature, and nature lives according to special laws that have been formed over many millennia. And if a person has adapted to lead a daytime lifestyle, then all the internal mechanisms that control his vitality work according to the daytime regime: vision is better, and hearing is thinner in the daytime; sunlight invigorates and makes you move more, which has a beneficial effect on blood circulation and respiration, and therefore on the speed of metabolic reactions; the central nervous system is more resilient during the daytime, while during the dark, many reactions of the nervous system are dulled; and, finally, the hormonal background is adapted precisely to daytime wakefulness and stress, which is reflected in a positive psychological disposition of a person for life.

But nature at the same time endowed the human body with a special set of functions, which allows not to be led by natural instincts, but to choose the mode of your life and rebuild it according to your capabilities and desires. But how such restructuring affects health, few people think.

What does wakefulness during the darkness bring to health? Nothing but disease! The first disorders that accompany nighttime wakefulness are mental disorders, many of which can begin with minor ailments: nervousness, overeating, drowsiness, overexcitation, increased tearfulness, poor sleep, nightmares, and thinking disorders. Further, the cardiovascular system is involved in the destruction process, the result of which failures are headaches, dizziness, increases and decreases in blood pressure, capillary hemorrhages, intracranial and ocular pressure disorders. The endocrine system, working in an extreme night mode, brings the body to an imbalance in the hormonal background, which will inevitably affect sexual functions, metabolic processes and mood.

When a person chooses a mode of life for himself, it does not hurt to ask the question whether his body will cope with the changed natural conditions of life. It is one thing to sometimes have fun at night, and quite another thing to work regularly at night, when the body, in addition to the aforementioned ailments, must also seek reserves in order to endure the burden of working time (physical and intellectual). The hour is not far off when the reserves will be exhausted and many systems in the body may fail.

But often life dictates its own conditions of survival, and in order not to lose health, it is necessary to be able to competently rebuild the body to work on the night shift. This requires gradually (adding an hour in the morning and subtracting an hour in the evening) to rebuild the sleep regime; sleep during the day in a darkened room so that the endocrine system produces the right hormones; take walks before going to bed in the fresh air; organize good lighting of the workplace (close to daylight); rebuild the diet taking into account the changed daily routine and do not forget about one of the main conditions for well-being - natural sunlight, for which choose time for daytime walks.
