Doctor Vu Quynh Nga, Vice Director of the Hanoi Heart Hospital, said that in winter when the temperature drops sharply, people may suffer from peripheral vasoconstriction, causing an increase in blood pressure. The risk will be higher when temperature change is more sudden and the temperature fluctuation is high, she said.

Measures for heart care

Nga said that in cold weather, human body’s circulatory system has to work harder to keep the body warmer, which means the heart has to beat faster and the blood vessels constrict, leading to faster heart beats and increased blood pressure. Thickened blood can create an increased risk of cardiovascular diseases such as stroke and heart attack.
