Despite the cooler weather and relief from the heat, the monsoon can cause changes in temperature, humidity, daily habits and lifestyles, which can impact individuals with underlying heart disease or conditions. One condition to be considered is atrial fibrillation (AF), a type of irregular heartbeat in which the heart can beat rapidly or irregularly.

Some people with AF may find that their symptoms are more noticeable when the weather is hot or cold, or when their usual routine is disrupted. While rain by itself is not a cause of atrial fibrillation, a few factors that occur with the monsoon can trigger it, especially in individuals who are at risk.

A stable temperature is maintained by our body at all times. Changes in temperature and humidity can influence heart rate, blood pressure and the body’s fluid balance. Individuals with heart disease might be more affected by these variations.

People also tend to alter their regular exercise habits, sleep routines and diet during the rainy season. These are also indirect effects on cardiovascular health due to decreased physical activity, increased salt/processed food intake, and alterations in fluid intake.

During the monsoon season, respiratory infections are more prevalent as well. When the body is already under stress due to an infection, fever, dehydration, or physical issues, these factors can further strain the body and can cause an irregular heartbeat in susceptible people.

There are multiple triggers for atrial fibrillation and they differ for each person. Common factors include high blood pressure, heart disease, excessive alcohol intake, stress, lack of sleep, thyroid problems and certain infections. Drying can also lead to a problem with the salt and mineral balance in the body that can impact the electrical activity of the heart. However, patients with heart or kidney disease should avoid consuming excess fluids.

That is why, for individuals who are known to have AF, changes in their fluid intake, medication, and activity should be based on the advice of their doctor, not the weather.

During an AF episode some individuals may have a racing (fluttering) heartbeat. Some may experience fatigue, dizziness, shortness of breath or discomfort in the chest. But in some instances, no symptoms may be noticed at all.

It is crucial to understand the significance of atrial fibrillation because in some cases, an irregular heartbeat is a risk factor for blood clots and stroke. The level of risk depends on each person’s specific situation, and this is why it is vital to seek a medical opinion if you think you have symptoms.

If you have a racing or irregular heartbeat, feel short of breath, dizzy, or unusually tired, it could be more than just temporary stress – consult a doctor.
