"All the factors of the external environment are of great importance for the cardiovascular system. These are dusting, excessive heat. Even the extreme cold. The big difference in temperatures in a short period of time is also a stress for the body. Any stress in the body leads to an increase in inflammation. So-called oxidative stress - one of the main mechanisms by which a cardiovascular disease can be destabilized. So warm weather is part of that mechanism." Cardiologist Prof. Ivo Petrov explained this on Nova TV.
And he advised: "In the heat, you should drink more fluids. And of course, if possible, do not stand in direct sunlight. Because this hypervasodilation, the dilation of the vessels, which the warm weather causes, can lead to dehydration and a drop in blood pressure, which of course is unfavorable.
In his words, "the nervous system is also involved to a large extent in the problem of very warm weather". "That is, when we have such stress as extreme heat, the nervous system also reacts adversely and this indirectly affects the heart," he pointed out.
