During periods of extreme cold, our body mobilizes to fight against the drop in temperature. The reactions that implements are likely to interfere with certain diseases, including heart or respiratory problems. The same is true for some drugs.

The cold weather aggravates certain diseases

When it’s very cold, the body increases by all means its heat production to maintain an adequate body temperature. In addition to shivering (reflecting muscle activity) and a general increase in metabolism, there is a cutaneous vasoconstriction (decreased blood circulation to the skin surface) and increased heart rate. Thus a period of extreme cold may aggravate pre-existing diseases, including cardiovascular and respiratory diseases, along with the risk of acute injuries such as hypothermia and frostbite.

Some medicines affect our defenses against the cold

In the same way, taking some medicines by cold weather can cause or exacerbate symptoms related to cold. For example, some drugs that act on the central nervous system may prevent it from triggering shivering or decrease blood circulation to the skin surface. In other words, certain medications may counteract the body in its reaction against the cold. An example of treatment against hypertension or angina pectoris, but also antiepileptics, neuroleptics and drugs that affect alertness.

Attention, It is stated that ‘in most cases, medication is not, in itself, a risk, especially if properly used. Other risk factors such as illness or old age, must be taken into consideration.
