It is often believed that cold weather causes an increase in heart attacks, and those with weakened hearts are more likely to suffer a heart attack or heart failure. Earlier, only the elderly experienced heart attacks, but today, heart attacks are striking young individuals in their 30s and 40s. Blockage of coronary arteries, or heart vessels, is the primary cause of a heart attack. The heart cannot provide oxygen and blood to the arteries when clogged, leading to a heart attack. Coronary arteries can get clogged for various reasons, but an erratic lifestyle is a primary culprit.Lets understand the causes of blocked coronary arteriesShrinkage of tubes in cold temperatures:Most heart attack instances are recorded as a result of these blood vessels contracting due to the cold weather in the winter. Therefore, it is recommended that those with heart problems exercise regularly, with extra caution.Less exerciseIn todays fast-paced world, people dont focus on exercise, leading to coronary artery blockages. The blood vessels get clogged if the body is inactive, resulting in slower blood flow via the muscles and blood vessels.CholesterolFast food and fried food consumption introduce poor cholesterol levels in the body, which damages the coronary arteries and causes blockages. The chance of a heart attack rises due to the hearts inability to receive blood smoothly.Stress & AnxietyHeart attacks can also be caused by stress and anxiety. According to medical professionals, mental stress raises the possibility of myocardial ischemia in the body. That is, when we get more stressed, the blood flow in the heart begins to become unbalanced, and in addition, stress prevents the heart muscles from receiving the oxygen they require, which increases the risk of a heart attack.
