Reasons for the increasing cases of cardiac arrests in winter

According to the study report from the National Institute of Health, about 17.3 million people die of cardiovascular disease globally. Seasonal variation plays a major role in mortality and morbidity in both the northern and southern hemispheres. There is a 31 to 33% increase in the incidence of heart attacks in winter. Experts from the Department of Cardiology comment that with a degree Celsius drop in temperature, there is a 0.49% risk of death. So, Is Winter a Heart Attack Season? Let us explore here. 

What causes more deaths in winter?

Experts suggest that the cold weather can be a culprit in causing more deaths during the winter season. Cold weather causes several changes in the body as the body strives to keep itself warm. Our blood vessels will become narrow as a response and have to put extra effort into pushing through the blood vessels to compensate for this. When the blood vessels that supply the heart constrict, it might lead to a heart attack. 

Experts in cardiology state that the volume of blood is higher during winter. This excess fluid will lead to higher blood pressure. Our blood also experiences a series of changes, such as,

  • Higher cholesterol levels
  • Platelet aggregation
  • Clot formation etc,

During winter months, these might result in both stroke and heart attack. People also refrain from performing physical activities during winter. They will also increase their food consumption to keep warm. Both these alter the blood cholesterol levels and predispose the person to heart attack. If you ask, Is Winter a Heart Attack Season? The answer is yes, as research studies also suggest the same.

Cardiologists suggest that older people and those who drink and smoke regularly are at the most risk of developing heart attack.
