As the monsoon brings welcome relief from the summer heat, it also ushers in a wave of health concerns—especially for those with heart conditions or a tendency toward low blood pressure. Cardiologists caution that the rainy season can impact cardiovascular health in unexpected ways.
Why Monsoon Affects Heart Health
“Monsoon is associated with high humidity and wide variation in temperature,” explains Dr. Anil Mishra, Senior Cardiologist, BM Birla Heart Hospital. “This leads to an increased incidence of viral and bacterial infections and also exposure to allergens like house dust mite.”
He says that chest discomfort during this season can often be attributed to chest infections or bronchospasm, particularly in patients suffering from bronchial asthma or chronic obstructive airway disease. However, there’s another angle to consider. “Wide variation in temperature can lead to peripheral arterial constriction which can lead to chest pains or angina,” he warns.
Dr. Pramod Reddy Kandakure, Clinical Director & Senior CTVS Surgeon at CARE Hospitals, Hitech City, Hyderabad, echoes similar concerns. “Monsoon weather can trigger fluctuations in blood pressure and increase the risk of chest discomfort, especially in people with pre-existing heart disease. Changes in atmospheric pressure and higher humidity can strain the cardiovascular system, so any unusual symptoms should never be ignored.”
Understanding Low Blood Pressure During the Rainy Season
According to Dr. Kandakure, the dip in blood pressure some people experience during the monsoon can be explained by environmental changes. “Sudden temperature changes, high humidity, and dehydration can cause blood vessels to dilate, which lowers blood pressure for some people. If you’re prone to low BP, you may feel dizzy, weak, or lightheaded, especially when standing up suddenly.”
When to Take Chest Discomfort Seriously
Dr. Kandakure advises that any chest pain, heaviness, or tightness that lasts more than a few minutes should be taken seriously—especially if it radiates to the arm, neck, or jaw. “Many people mistake early signs of a heart attack for gastric trouble during this season. Timely ECG and cardiac evaluation can be lifesaving.”
Dr. Mishra adds another layer, pointing to the indirect effects of the season. “People who suffer from heart failure can develop fluid overload due to high humidity and can develop shortness of breath or swelling of feet. Also note that during monsoons, because of decreased sunlight, serotonin levels in the body can go down, leading to some low feelings and depression.”
He also points out dietary triggers: “Rich food during monsoons—which often includes fried items and heavy meals—can lead to reflux in the food pipe, giving rise to discomfort in the chest. So avoiding these by not overeating and eating healthy is an easy thing to do.”
Precautions to Take
“Stay well-hydrated, avoid sudden exposure to cold rain after being in heat, and monitor your blood pressure regularly,” advises Dr. Kandakure. “Stick to your prescribed medications, avoid excessive salt intake, and don’t ignore any new or worsening symptoms like swelling in the feet or breathlessness.”
Dr. Mishra recommends simple but effective measures: “Avoid contact with people having cold, cough and fever, maintain proper hand hygiene, remain adequately hydrated, and avoid dust and allergens. Seek medical attention at the earliest if symptoms occur or persist.”
Managing Low BP at Home
“For those who often feel faint or tired due to low BP,” says Dr. Kandakure, “increase your fluid intake, add a pinch of salt to your diet if advised by your doctor, and avoid standing up abruptly. If symptoms persist, consult your physician to rule out any underlying heart or endocrine issue.”
