Health experts have warned that cold temperatures increase the risk of infection By strokeThe risk of hospitalization due to stroke increases by 6% for every five-fold drop in temperature during the winter months, according to what was published by the Health and Me website.
The effect of cold weather on blood vessels
Cold weather causes blood vessels to constrict due to an increase in vasoconstrictive substances such as noradrenaline, which leads to high blood pressure, which is a major risk factor for stroke. In addition, winter or cold weather increases the possibility of platelet aggregation and disturbs the balance of the clotting and glycolysis process. Clots, which facilitate the clotting process. Blockage in one of the blood vessels leading to the brain due to blood clots is one of the main causes of a major stroke.
Humidity contributes to an increased risk of stroke, as high humidity in the atmosphere can cause some people to become dehydrated, which increases the risk of blood clots forming, and with high humidity, the risk of stroke increases.
