Myth: when traveling to warm countries, you’ll be sure to get sick in the first days (acclimatization)

As a matter of fact. Acclimatization is the process of adapting the body to new climatic conditions, but there is no evidence that it makes a person more vulnerable to viral diseases. According to the pediatrician Fyodor Katasonov, acclimatization is considered as adaptation to a change in temperature or other conditions, for example, to a change in altitude (and, accordingly, the level of oxygen in the air). "Adaptation of thermoregulation to hot conditions consists in changing the functioning of the cardiovascular system (increasing heart rate and decreasing stroke volume of the heart), kidneys (decreasing salt in urine and urine volume), sweat glands (increasing sweating and reducing salt in sweat), blood vessels ( expansion). This leads to cooling and reduced fluid loss.

Adaptation to high altitude conditions involves increasing the hemoglobin content in the blood in order to more efficiently nourish the tissues with oxygen, which is low in the air, "explains Fedor Kataso new That is why acclimatization is mainly of interest to specialists from the point of view of exacerbation of cardiovascular diseases or, for example, from the point of view of the body's ability to withstand certain physical activities.

However, we will not argue that people often get sick after moving. There are several hypotheses with which this may be associated. First: the road is to blame for everything. Airports and stations are terrible breeding grounds for infections.

The second hypothesis: the impact of ultraviolet (in large quantities it can weaken the immune system). Third: the failure of the biological clock (during long-distance flights) - this can negatively affect immunity.

In order not to get sick at the very beginning of the vacation (at least significantly reduce the risks), follow these simple recommendations:
