Find out the dangers that heat brings to people with heart disease

The whole country is already under the effect of summer season and scorching temperatures. These temperatures are more dangerous especially for children and the elderly.

Extreme heat is also extremely dangerous for people suffering from cardiovascular diseases. When temperatures are high, heat in the body moves from warmer to cooler areas. b As long as the surrounding air is colder than the body, the organism radiates heat into the air. This radiation stops as soon as the air temperature approaches that of the body. This makes the heart beat faster and pump more blood.

On a hot day, the heart circulates two to four times more blood per minute than on a cool day. On a non-humid day, the evaporation of sweat significantly cools the whole blood. But when humidity rises above 75%, evaporation of sweat becomes extremely difficult. This increases the pressure on the cardiovascular system. Sweat removes more heat from the body, along with many minerals beneficial to nerves, muscles and fluid balance. This forces the body to release more hormones that help the body retain more water and minimize mineral loss.

Healthy people manage to have a higher tolerance to temperature changes. People who have heart problems have a more stressed organism and are therefore hit harder by the heat. The heart in people who have had an attack has a harder time pumping enough blood to cope with the heat. Clogged blood vessels due to cholesterol have poor blood circulation in the skin. Ischemia, Parkinson's, Alzheimer's, Diabetes and others negatively affect the brain's response to dehydration. Thus, the brain fails to send the thirst signals and the body suffers the consequences.

Experts recommend that people who perform physical activity, do it in the early morning or late evening. At the peak of the heat, be sure to stay in an air-conditioned environment, take a bath or apply cool compresses under the armpits. On hot days make sure to drink water every hour. Do not drink carbonated, sugary, alcoholic or caffeinated liquids that worsen dehydration and try to stay in the shade as long as possible.
