Heart attack cases are on a rise globally. Medical experts all over the world claim that people are more susceptible to heart ailments during the winter season. There are multiple reasons and factors why heart attack cases rise in winter, but following certain lifestyle tips can help you mitigate the risk.

Health Shots got in touch with cardiologist Dr. Komal Pawar, who tells us why heart attack cases increase in winter and how to maintain heart health.

Is it possible to have a heart attack due to cold weather?

The winter season can have a direct impact on the way our body functions. It can constrict blood vessels and coronary arteries, which directly impacts how blood flows across the body. In winter, people also engage less in physical activities due to the low temperature. Besides, the chilly season can take a toll on heart health in many ways. Read on to find out!

1. Increase in blood pressure

Cold weather can lead to a higher blood pressure, and other heart health related risks, notes a study published in Experimental Physiology. The chances of heart attacks in the cold weather is much more compared to any other time. “In the cold, there is a constriction of blood vessels, and this increases blood pressure. In turn, this puts extra strain on the heart. Especially, if you have any pre-existing cardiovascular conditions, this extra stress and pressure on the heart can lead to a heart attack,” explains Dr Pawar.

2. The body can get exhausted

In the cold weather, the body needs to put a lot of effort to maintain the right  temperature. While doing this, it takes away the energy and resources from other systems such as the cardiovascular system. This is what makes your heart health suffer, explains Dr Pawar.

3. More frequency of strokes

A study published in Heart Rhythm points to the fact that strokes due to blood clots, experienced by patients with atrial fibrillation, happens the most during the winter.

4. Respiratory infections

During the winter, people have more respiratory infections, such as influenza and pneumonia. “These respiratory diseases leads to more strain on the heart. So if you already have compromised cardiovascular health, this can make your condition worse. Also, the inflammatory response which are caused by the infections may result in the development of arterial plaques, increasing the risk of a heart attack,” says Dr Pawar.

5. Lifestyle choices

We make many lifestyle changes in the winter time, and this can lead to poor heart health as well. We reduce our physical activity , and end up putting on weight. There is also an overall decrease in cardiovascular fitness, explains Dr Pawar, adding, “The holidays also put stress on our bodies and hearts, plus our diets go for a six. All this can lead to elevated blood pressure and increased cholesterol levels, both of which are known risk factors for heart attacks.”

6. Less exposure to sunlight

We don’t have too much exposure to the sun during the winter months and this can cause a dip in vitamin D levels. This has a direct affect on your heat health and our chances to having a heart attack increase.
