Stress, Sleep Loss and Long Hours Are Driving Heart Rhythm Disorders Among Indian Professionals

Cardiology clinics in India are seeing a particular kind of patient more often: a young or middle-aged professional who arrives with a racing heart, an irregular beat, chest discomfort that has no obvious cause, or a sudden jump in blood pressure. According to cardiologists interviewed by India Today, many of these patients have none of the usual risk factors, such as diabetes or high cholesterol.

Dr Shubham Kumar Sharma, a consultant in the cardiology department, describes the rise in stress-related heart problems among working professionals as sharp. In his telling, the heart is paying for long work hours, poor sleep and constant mental pressure. He sees this as a shift away from heart disease tied to age and toward cardiac strain tied to how people live and work.

His explanation starts with the body's stress response. Chronic stress, he says, holds the body in a constant fight-or-flight mode, releasing hormones that raise heart rate and blood pressure. Add late nights, heavy screen exposure and too little sleep, and the heart's natural rhythm and its recovery cycle are disrupted. Over time, he says, that strain can bring on arrhythmias such as atrial fibrillation or frequent premature heartbeats, even in people who are otherwise healthy.

Dr Anjan Siotia, Director of Cardiology at BM Birla Heart Hospital, points to the same mechanism. Chronic mental strain, long working hours and disrupted sleep, he says, directly affect the heart's electrical system. Persistent stress raises hormones such as cortisol and adrenaline, which can trigger palpitations, irregular rhythms and sudden blood pressure spikes. Poor sleep makes it worse by disturbing the body's circadian rhythm, leaving the heart more open to rhythm disturbances such as atrial fibrillation and frequent extra beats.

Both doctors say the larger problem is delay. Dr Sharma notes that these symptoms are often written off as anxiety or work-related fatigue. Dr Siotia says many young professionals treat a racing heart, unexplained fatigue, breathlessness or light-headedness as burnout, and put off seeing a doctor. Left unaddressed, he says, the combination of stress, sleep deprivation and sedentary habits can quietly progress to serious cardiac events.

For that reason, Dr Sharma argues that protecting the heart is no longer only a matter of avoiding a heart attack. It also means preventing long-term rhythm disorders that can affect quality of life and productivity. His list of priorities is managing stress, putting sleep first, staying physically active and getting an early cardiac evaluation. Dr Siotia adds that regular health checks, and prompt evaluation of symptoms that persist, are essential in a high-pressure work culture.

The article gives no patient counts or study figures behind the reported rise; it rests on the clinical observations of the two cardiologists. The practical advice is clear, though: a racing heart or recurring light-headedness that doesn't go away is worth taking to a doctor rather than explaining away as burnout.
