This is fine. Our body so adapts to the heat. It will be easier to understand if you remember how your temperature rose during your illness and chills appeared.
It was so? Then the hands and feet become cold. Children are especially reactive. Their hands instantly become icy when their body temperature rises.
In the case of a cold, our body for some reason thinks that it is cold and, in order not to lose heat, constricts the blood vessels in the arms and legs. This way we give off less heat to the environment. This is stupid behavior on the part of our body, because in fact at that moment the body temperature is high, and it must, on the contrary, be reduced.
In hot weather, things are different. The body is already smarter and if it feels that it is starting to overheat, which, on the contrary, expands the blood vessels in the skin of the hands and feet.
If you remember, you will immediately understand that exactly those places that were cold with a cold became swollen in the heat. Edema occurs due to the fact that water is poorly retained in the dilated vessels and slowly sweats into the surrounding tissues. The hands and feet are swollen.
In general, this is a short-term phenomenon. It happens to those people who have not yet adapted to the heat. The body is smart and will not keep the hands swollen all the time. He will find another way of thermoregulation. After a few days, acclimatization will come and the swelling will diminish.
For three days in Vietnam my hands were swollen and my head hurt. This is the same acclimatization.
Therefore, if you find yourself in an unusual heat for you, then remove the rings in advance, and squeeze and spread your fingers more often. This reduces the swelling.
Did you have anything else interesting from the heat?
