Why are heart problems more prevalent in the winter?

Various health issues are seen throughout the winter. Many individuals have serious medical disorders in addition to an increase in the prevalence of the typical cold, sore throat, and flu. Actually, exposure to cold might inevitably affect the heart as well.

The likelihood of a heart attack and stroke rises as the temperature lowers because constricting blood vessels are a result. The chest discomfort becomes greater in winter as a result of coronary artery restriction.


The outside temperature and blood pressure have an inverse connection, according to Dr. Hisham Ahamed, Consultant Interventional Cardiologist and Clinical Associate Professor, Cardiology, Amrita Hospital, Kochi.

"Wintertime blood pressure increases cause the heart to work more to pump the same volume of blood. Our blood arteries are thin, thus this boosts blood flow to the inner organs, which are located closer to the heart, in order to maintain a constant body temperature "India Today said Dr. Ahamed.

The outcome is a reduction in blood flow to the skin and limbs, which are located farther from the heart.

"The heart needs to work harder to pump blood through narrowed blood arteries, and occasionally the blood may be more prone to clotting if this happens," he said.

Additionally, at lower temperatures, blood platelets bind to one another more often. Although platelets often cluster together to form clots that help to stop bleeding wounds, Dr. Ahamed added that cold weather raises the risk of a potentially lethal blood clot growing within the body.

Studies show that heart attacks and heart disease-related issues are more prevalent in the cold early hours. "Recent research indicates that this often happens as a consequence of an increase in blood pressure in the morning. Additionally, mornings have an imbalance in sympathetic hormones that raises your risk, "he Dr. Ahamed said.

Increased levels of clotting factors, notably fibrinogen, are caused by hormonal changes. "The sympathetic tone tightens blood vessels throughout the winter. Blood pressure and heart rate are controlled by the sympathetic nervous system and the body's regulatory system. In addition to this, heart attacks in the winter may result from plaques rupturing as a result of blood pressure increases "explained he.

The likelihood of the issue rises for someone who is predisposed to heart attacks owing to inactivity throughout the winter and weight gain. Even worse, they wind up eating more, which raises cholesterol and promotes weight gain. Low vitamin D exposure is another issue that has an impact on the heart. Numerous studies have linked poor cardiovascular health to low vitamin D levels. Heart issues have been directly related to low vitamin D consumption.


A healthy lifestyle may be changed, as Dr. Tapan Ghosh, Director and Head of Cardiology and Head of Clinical Research at Fortis Hospital Vasant Kunj, previously discussed with India Today. While increasing fruit and vegetable consumption, one should also engage in physical exercise for at least 30 to 40 minutes each day.

"Every day should include a vigorous stroll. Additionally advised are other hobbies including swimming, cycling, and running. These exercises are known as isotonic ones. The heart benefits from it. Weightlifting, which is a kind of muscular workout known as isometric, is not good for the heart "Dr. Ghosh informed us, adding that other lifestyle choices should be made to cut down on things like drinking alcohol and smoking.
