Rest turned into disease >>>> Acclimatization

Acclimatization.

Very often, the rest is accompanied by a move from a cold climatic zone to a warmer one and vice versa. And if this move has a beneficial effect on the emotional background of a person, then such a sharp change in climate has a stressful effect on the functional work of the body as a whole. Why?

Over the years of evolution, the human body, surviving in a changeable environment, has created a compensatory system that is responsible for adaptation: it regulates heat exchange, metabolic processes, maintaining the body in a normal state.

There are a number of processes that have to be rebuilt by an organism that has fallen into new climatic conditions.

Firstly, different climatic zones imply a different temperature regime of the environment, which means that the human compensatory system begins to rebuild the heat exchange reactions, slowing down or increasing their speed. The consumption of nutrients changes upwards or downwards, which in turn will lead to an acute shortage of these substances, or to their excessive presence in the body. And since in order to maintain good health, the human body requires a balanced complex of nutrients, any deviations in their quantitative composition will inevitably lead to disruptions in the work of an organ or a functional system as a whole. For example, digestive disorders, cardiovascular disorders, and brain function are possible.

Secondly, heat exchange processes are in direct proportion to the blood flow velocity. With an increase in ambient temperature, the blood flow rate and, accordingly, the volume of circulating blood in certain places of the vascular system decreases, due to the fact that there is no need to additionally heat the vital internal organs (heart, kidneys, liver, etc.). A decrease in the rate of blood flow can affect the work of the brain, which under normal conditions is accustomed to a certain mode of blood supply, which will lead to excessive fatigue, drowsiness, decreased appetite, lethargy, dizziness, and headaches. With a sharp decrease in ambient temperature, the blood flow to the internal organs increases, the lumens of the vessels expand to increase the speed of blood movement in the desired direction. Such changes will not be able to pass unnoticed for the cardiovascular system and will be reflected in unhealthy phenomena: surges in blood pressure, vascular spasms, arrhythmias, rupture of blood vessels in places where their tissue was not elastic enough.

Thirdly, different weather conditions entail not only a change in the temperature regime, but also a different degree of air humidity, which will affect the operation of the sweating system. The higher the air humidity, the harder it is for the body to adapt to the environment. High air humidity especially worsens the condition of people suffering from chronic diseases of the respiratory system, cardiovascular system.

Fourthly, different climates are different diets and unusual food products. The usual diet for the body will be disrupted, which can cause disorders of the digestive system (dyspepsia).

Fifthly, different time zones will lead to disturbed sleep patterns, which always affects the functioning of the human nervous system, can cause insomnia, headaches, nervousness, and increased fatigue.

The process of acclimatization of an organism is not lightning fast and requires a certain time interval, in this regard, there is a distinction between partial and complete acclimatization .

The average statistical time for partial acclimatization is a week, and full acclimatization requires a much longer period of time: up to a year or more.

Considering the above-described negative consequences for the body when the climate changes, it can be understood that a trip to another climatic zone for a week and return to the usual natural environment will not be painless for the body. There will be some weak spot in health, some kind of chronic painful process that will "break out" and give an impetus to the development of the disease. Therefore, it is very important to have an idea of how to properly prepare for acclimatization and help the body go through this process without loss.

There are several rules that contribute to the successful acclimatization of the body:

The travel time to another climatic zone should be calculated so that a person has a week to acclimatize, plus at least three to four weeks to stay in the chosen climate.

Clothing should be selected in such a way that as you move from one weather condition to another, you have the opportunity to gradually take off part of your clothing and also gradually put on. You should not change your fur coat, coat to shorts, swimsuit, or vice versa. This must be done in order to avoid overheating or hypothermia of the body.

The first week of rest in a different climate is given for correcting and restoring sleep patterns, so you should not arrange violent entertainment for yourself during this period, it is better to sleep longer so as not to overwork the nervous system (you will still have time to overwork it at work). The best option would be a gradual, premeditated restructuring of sleep and wake times before the trip begins.

It is worth taking a closer look at the organization of the daily routine and walks of local residents and imitate, if possible, their regime (for example, you should not go shopping during the siesta period, try to swim in the sea or ocean during a storm, ski in a blizzard, arrange tropical showers during the season walks).

In nutrition, you must initially adhere to the usual dishes, gradually adding exotic to the diet. If your body is not used to assimilating fatty or spicy food, insufficiently thermally processed food, do not rush to try delicacies, otherwise you have every chance of getting gastroenteritis at best , and poisoning at worst. Both that and another will spoil the rest thoroughly.

It is no secret that, returning from vacation, a person expects to feel rested, but in reality he often feels tired. The process of acclimatization has begun again, and we must have time to survive it before going to work. Therefore, learn how to properly manage your vacation time so that it does not end with sick leave for you.
