Heat waves can affect heart health: Study

Summer heat in India is getting stronger every year, and it is now becoming a serious health concern. According to reports by the India Meteorological Department (IMD), heat waves are happening more often and lasting longer than before.

Studies supported by the National Institutes of Health (NIH) have also reportedly shown that extreme heat can increase stress on the heart and raise the risk of heart-related problems.

As per reports citing these studies, when the weather becomes very hot, the body works harder to stay cool. Blood vessels widen and the heart pumps faster to control body temperature. This puts extra pressure on the heart, especially during long periods of heat and humidity.

Heat waves can also cause dehydration because the body loses a lot of water through sweating. When there is less fluid in the body, blood circulation becomes difficult and the heart has to work harder. This may lead to weakness, dizziness, headaches, tiredness, or sudden changes in blood pressure.

Along with water, the body also reportedly loses important minerals like sodium and potassium through sweat. These minerals help control heartbeat and muscle function. Their imbalance can sometimes lead to heart palpitations, muscle cramps, or irregular heartbeat.

Another major danger during extreme heat according to reports  is heat stroke. This happens when the body is unable to cool itself properly. Heat stroke can affect important organs like the heart, brain, and kidneys, and may become life-threatening if not treated quickly.

People with existing heart problems, high blood pressure, or older adults are considered more at risk during heat waves. Experts advise staying hydrated, avoiding direct sunlight during afternoon hours, wearing light clothes, and taking rest whenever needed.
