We are not all equal in the face of strong heat. Some people remain particularly fragile when temperatures rise in summer. We think ofPeople over 65, infants, pregnant women as well as to people who are victims of chronic diseasessuch as hypertension or heart failure.
However, be aware that anyone can be a victim of heat.
During a heat spike, the body triggers adaptation mechanisms such as sweat. When your body temperature exceeds 37°C, your body activates mechanisms to thermal regulation : he begins to sweat and breathing quickens. The heat is then eliminated via the water and the steam released. During this time, the blood vessels on the surface of the skin increase in diameter (vasodilation) to cool the blood.
THE heart is also harmed. During a heat wave, the skin vessels dilate and the blood is distributed towards the extremities. The heart is then forced to pump more, thus increasing the heartbeat 10 to 15 beats per minute more, even at rest.
Heat waves can therefore be dangerous, even fatal. What are the warning signs? The right steps to protect yourself? Top Health spoke with Thomas Kassab, community pharmacist.
