With the cold, let's think about our hearts!

With the cold, let's think about our hearts!

Avoid, above all, going outside for a cigarette after a stressful meeting. Tobacco, cold and stress contract the blood vessels, multiplying the risk of heart attack. The number of cardiovascular accidents increases in winter.

Exposed to sub-zero temperatures, the heart beats faster, oxygen consumption increases and blood vessels contract, leading to blood clotting and greater viscosity - all the more so as cold dehydrates.

According to a study carried out in the UK and published in the British Medical Journal on 84,000 hospital admissions, every 1°C drop in outside temperature increases the number of heart attacks by 1% to 3% over the following four weeks.

Let's cover up and avoid strenuous exercise in sub-zero temperatures. And don't forget to drink regularly, because the cold dehydrates!
