Heat wave and cardiovascular health

The high temperatures we are experiencing this August are not only uncomfortable, they also pose a real risk to the heart.

Extreme heat can decompensate people with previous heart disease, increase blood pressure or cause severe dehydration, which increases the risk of heart attack, arrhythmias and other cardiovascular events.

Especially in older adults, children and people with previous pathologies, the heart works harder to maintain body temperature, and this can have serious consequences if preventive measures are not taken.

What can you do to take care of your heart during the heatwave?

The first step is to understand that excessive heat affects the whole body, but the cardiovascular system is particularly vulnerable. Here is a practical guide to protecting your heart health during these hot days:

Stay hydrated constantly.

Don't wait until you are thirsty to drink water. Dehydration thickens the blood, which increases the risk of thrombosis and overloads the heart.

Avoid exposure to the sun at critical hours.

Between 11:00 and 18:00 the sun's radiation and heat are most intense. If you need to go out, wear light, light-coloured clothing, a hat and sunscreen, and always look for shade or ventilated places.

Control your medication and blood pressure.

If you are hypertensive or take diuretic medication, consult your doctor. Some medications may change their effect in the heat or promote dehydration.

Avoid strenuous physical exertion.

During heat waves, the heart works harder, even at rest. Strenuous exercise can easily throw you off balance. Opt for gentle routines and cooler times, such as in the morning or evening.

Pay attention to the warning signs.

If you feel palpitations, sudden fatigue, chest pain, shortness of breath or dizziness, don't ignore it. Go to the emergency room or contact your cardiologist as soon as possible.

Take care of those around you.

Elderly people, children and chronic patients are especially vulnerable. It helps monitor their hydration, temperature and general well-being.
