How to care your heart in winters?
Winter comes with some of the major risk factors for heart diseases, respiratory diseases and highly contagious viruses. People often view the danger as hypothermia or frostbite. This dropped temperature during winter directly impacts your health and brings people of heart disease to maximum risk of heart attack or cardiac arrest.
Why heart attacks cases increase in winter?
Heart attacks are common in winter season. There are several theories mentioning the cause of heart attack in winter.
The main risk factor is body’s physiological mechanism – In human body, we have autonomic nervous system of which one component is sympathetic nervous system whose activation increases in winter and narrow our blood vessels, and this narrowing is called vasoconstriction. This also leads to increase in the blood pressure of body. Due to the vasoconstriction, the blood flow is decreased and the heart needs to work extra hard to pump the blood and keep the body temperature maintained. The cold wind in winter makes it difficult to keep the body’s temperature maintained and loose heat quickly which leads to hypothermia which can damage muscles of heart.
Another main risk factor is oxygen requirement – In winter season, the oxygen density in atmosphere becomes low. Hence, oxygen demand of heart increases. Due to vasoconstriction (narrowing of artery) and decreased temperature, the flow of blood restricts around the heart and so reduced amount of oxygen reach to heart and this demand supply mismatch may cause a heart attack.
Sometimes you may get affected by the one of these factors, physical inactivity or emotional stress which contributes to increased risk of heart attack in winters. So you should be more cautious and take extra precautions about it as per the top cardiologist of lucknow.
