Does the risk of heart disease increase in the winter?  

Heart Disease Increase

Some diseases increase with the festival of eating winter traditional cake. Such as skin problems, fever, cold, cough, etc. At the same time, the risk of high blood pressure, heart pain, heart attack, and death increases with the increase in severity of winter. As the temperature drops, many feel like a stone is pressed against their chest. Every year, the number of people suffering from heart disease increases by 30 to 50 percent during the winter. Research has proven that winter can increase blood pressure by 12 to 18 mm.

Why is this so?

A sudden change in temperature affects the heart as well as other parts of the body. In winter, the ‘ympathetic activation’ of the nervous system increases in our body. Therefore, the sympathetic activation of the nervous system narrows the blood vessels. This is called ‘vasoconstriction’. It increases blood pressure in the body. So the heart has to work twice as hard to pump blood throughout the body. When the outside temperature drops a lot, it becomes difficult for the body to maintain its normal temperature. It can lead to hypothermia, which damages the blood vessels in the heart.

In people who already have heart disease, their bodies struggle to adapt to this situation. On top of that, the body needs more oxygen in the winter. Vasoconstriction causes blood vessels to narrow. Therefore, less oxygen reaches the heart. This increases the risk of heart disease.

The risk of heart disease increases due to some other reasons in the winter. When it’s cold, everyone gets a little more cozy. Decreased desire to walk or exercise. The diet also changes. Foods that are consumed in excess increase cholesterol levels in the body. Weddings, invitations, and festivals increase in our country in the winter.

Asthma, or asthma, increases in the winter. May suffer from allergic problems. Complicated respiratory infections make it difficult to get oxygen. Then pressure can fall on the heart muscle.


What to do:

Avoid foods that increase cholesterol or blood pressure.

Despite being busy, one should still attempt to exercise.

Try to keep your body warm by understanding the outside temperature. Wear proper winter clothes to avoid getting cold.

Elderly heart patients should bathe with lukewarm water every other day instead of bathing every day. Bathing in very hot water has adverse effects on health.

Follow your doctor’s advice by doing regular health checkups. be careful
