Heart to the test of the heat wave

Heart to test the heat wave: how strong heat affect cardiovascular health

In summer. Therefore, Mercury came close to records in several cities in France. For example, In Nîmes, on July 1st, temperatures reached 41.3 ° C, a summit never seen since 1943. Moreover, In question? For example, planetary thermal warming.

But beyond everyday inconvenience, these waves of extreme heat seriously worry cardiologists. Meanwhile, Because if the whole body suffers, The heart is on the front line against thermal stress.

Heart to the. Therefore, test of the heat wave

A heart test heat wave planet that heats up …. Consequently. In addition, a heart that gets carried away

According to the IPCC data (group of intergovernmental experts on climate evolution), the land should cross the symbolic threshold of a warming of +1.5 ° C from 2030ten years earlier than expected. Nevertheless, Result: an increase in extreme climatic events that affects not only the environment … but also human health.

The World Health Organization (WHO) believes that global warming is responsible for more than 150,000 deaths per year in the world. And people with cardiovascular pathologies are among the most vulnerable.

Why does the heart suffer from heat? – Heart test heat wave

The human body normally operates around 36 ° C. When it is too hot. it deploys several mechanisms to evacuate excess thermal: sweating, dilation of blood vessels, acceleration of heart rate.

But these adaptations have a cost:

• Dehydration : excessive sweating without sufficient. water intake of water leads to a drop in blood volume. which can cause a voltage drop.
• Blood thickening : more viscous blood increases the risk of thrombosis or embolism.
• Tachycardia : The heart must beat faster to ensure thermoregulation.

Insolation: an underestimated danger

Prolonged sun exposure can cause a insolationa serious thermal regulation disorder. Symptoms: fever, headache, confusion, nausea, red and dry skin, even loss of knowledge.

This clinical picture requires rapid management, because The insolation can be fatal if it is not treated in time.

Blood pressure: the big gap

In summer. the extremes meet:

• On the one hand. heat dilates the vesselswhich can heart test heat heart test heat wave wave cause a hypotension (Pressure too low), especially if you are standing for too long.

• On the other. excess food and alcoholfrequent during barbecues or summer parties, can climb tension… And the risk of stroke or infarction.

THE hypertensive people or suffering fromheart failure must redouble vigilance.

• Drinking regularly (water. diluted juice, coconut water), even without thirsty
• Avoid direct exposure to the sunespecially between 11 a.m. and 4 p.m.
• Settle in a fresh. ventilated placeeven air conditioning
• Wearing clear. light and loose clothes
• Eat light : heart test heat wave fruits, heart test heat wave vegetables, dishes that are not very salted and easy to digest
• Avoid alcohol and caffeinewhich accentuate dehydration
• Do not stand for too long – in case of discomfort, lie down and raise your legs
• Forget home remedies like salt under the tongue to bring up tension: ineffective and potentially dangerous

What to remember

Heat waves are no longer exceptional events. They become the norm in many regions of the world. The heart, vital organ, pays the high price of this new climate reality. Prevent is better than cure: staying in the shade. well hydrated and adopting an adapted lifestyle are the best allies to cross the summer without worry … and without tachycardia.
