But there’s another cause of concern which many people might not even be aware of. Cold weather can cause blood vessels constriction, increase in heart beats which can raise blood pressure due increased sympathetic tone and also increased clot formation tendency of body, thus increasing the risk of heart attack and stroke.
As a matter of fact, chances of heart attacks goes up by nearly 33 per cent during winter. Needless to say, it is imperative that people should take adequate care to stay warm during the winter. Elders specifically tend to be vulnerable during these cold months as the cold can cause a dramatic drop in their body temperature thus leading to hypothermia. If the body temperature dips under 95 degrees, the resulting hypothermia can cause severe damage to the heart muscle. Further, patients afflicted with Angina need to be particularly careful as the cold weather can cause coronary arteries spasm leading to heart attack.
