When very high temperatures are recorded for several consecutive days, associated with high humidity and lack of ventilation, we speak of heat waves. A climatic condition that is not without consequences on our body. What happens inside us, how to avoid health risks and who above all must be protected? We asked Dario Manfellottoof the Department of Medical Disciplines of the Fatebenefratelli-Isola Tiberina in Rome and national president of the Federation of Hospital Internists Managers.
“The increase in the internal temperature of our body changes its balance. Among the consequences are vasodilation, sweating, and therefore dehydration, the risk of organ deterioration. The brain is also affected, a state of confusion, “explains the doctor.
To defend ourselves, situations in which we are exposed to a build-up of heat, such as exercising under the sun during the hottest hours, should be avoided. And you need to hydrate continuously. Particularly fragile people who have altered thermoregulation mechanisms such as the elderly, the chronically ill and the sick with multiple pathologies must be adequately protected.
Heat stroke: how to recognize it and intervene
Heat stroke. What causes it, what are the symptoms and how to intervene
One of the greatest risks that can be run in these climatic conditions is the heat stroke. “It occurs when the body accumulates heat beyond a certain amount and is no longer able to respond with sweating. The internal temperature can rise up to 40 degrees. The brain suffers from it, it can lead to a state of confusion, to loss of conscience, in some cases to a coma “, explains Manfellotto.
Drink a lot, but how much?
Hot, drink a lot. How much? The answer is not the same for everyone
The advice that you hear more often in times of great heat is to drink more than usual. But there is no quantity that can be indicated to everyone. “Normally a liter and a half or two is recommended depending on the state of health and the heat: but you have to drink water according to how much we can eliminate. Those who have heart failure or suffer from kidney failure, for example, should ask their doctor what limit not to exceed “explains Dario Manfellotto.
