Asthmatics and people with migraines or back pain feel the frosty cold that literally draws into the body especially. Heart patients should also act cautiously at the current temperatures. The reason: “Extreme cold can lead to a heart attack or sudden cardiac death in the case of exceptional stress,” said cardiologist Prof. Thomas Meinertz WDR.

The reason is that the body wants to protect the most important organs of the body from cold. This means top performance for the heart because it has to pump harder. The most important organs of the human body are located in the middle of the body and in the head, and in order to protect them, the body contracts the vessels in the arms and legs in the cold. The goal is to reduce the blood flow there so that less cold blood flows into the core of the body. For the heart, this also means that there has to be a greater resistance to pumping. Because of the lower blood flow, fingers, toes and ears cool down first. The risk of frostbite is therefore greatest there.
