Why your daily commute may be damaging your heart, lungs, and brain, and simple ways to reduce the risk

For many people, the day does not begin at the office. It begins in traffic. A commute that stretches to 2–3 hours each day may feel routine, but the body does not treat it as neutral time. It treats it as stress.That daily exposure to noise, polluted air, crowded spaces, and long periods of sitting can slowly strain the heart, irritate the lungs, and overload the brain. Over time, this “invisible stress window” becomes one of the most consistent health risks in urban life.A commute combines several stress triggers at once. There is unpredictability, lack of control, and constant sensory overload.Traffic jams force the brain to stay alert. Honking and noise keep stress hormones elevated. Poor air quality adds a physical burden. Even if the body is still, the nervous system is not.As Dr Keshava R explains, “Daily commute, often lasting 2–3 hours, forms a significant and stressful part of our routine. Prolonged exposure to traffic congestion, air pollution, and noise increases the risk of high blood pressure, heart disease, and respiratory issues.”This is not just discomfort. It is a sustained biological response.Men's health: Doctor shares early signs of low testosterone and if over-the-counter supplements helpThe heart responds quickly to stress. Even mild stress can raise heart rate and blood pressure. Now imagine this happening every single day, twice a day.Long commutes are linked with:A large body of research supports this. A report from the NIH found that longer commute times were associated with poorer cardiovascular health outcomes.In India, urban air pollution adds another layer. The Central Pollution Control Board (CPCB) has repeatedly highlighted high particulate matter (PM2.5) levels in peak traffic hours.These fine particles enter the bloodstream and can trigger inflammation, which stresses the heart further. The lungs are the first to take the hit. During peak traffic, pollution levels rise sharply, especially in enclosed roads and intersections.Two-wheeler riders and those using open or non-AC transport inhale more pollutants. Even short exposure can irritate airways. Long-term exposure can lead to:Dr Keshava R notes, “Two-wheeler riders and those in non-air-conditioned transport are especially vulnerable to harmful pollutants.”Studies by India’s Ministry of Environment, Forest and Climate Change (MoEFCC) show that vehicular emissions are a major contributor to urban air pollution.Evening commutes tend to be worse because pollutants accumulate through the day.The brain reads traffic as a threat environment. There is unpredictability, sudden braking, noise, and visual clutter.This keeps the stress hormone cortisol elevated. Over time, this can affect:It also explains why people often feel mentally drained before their workday even begins.There is a simple question worth asking: why does sitting in traffic feel more exhausting than physical work? Because the brain is constantly processing stress signals, even when the body is still.A long commute often means prolonged sitting. This adds another layer of risk.Sedentary travel is linked to:Research from the Australian Government Department of Health has shown that long periods of sitting increase the risk of chronic disease, even if a person exercises later.In simple terms, the commute cancels out part of the day’s movement. Many people notice that returning home feels more draining than the morning trip. There are clear reasons.By evening:Dr Keshava R highlights this clearly, “Evening commutes tend to be worse due to higher pollution levels.”This is when the combined effect on the heart, lungs, and brain is strongest.The commute may not be avoidable, but its impact can be reduced with small, consistent changes.Dr Keshava R suggests, “To reduce risk, individuals should consider travelling during early hours, using metro or air-conditioned transport with air recirculation, and incorporating small lifestyle changes like walking short distances or practicing relaxation techniques.”Some practical ways to ease the strain:Urban life often celebrates productivity, but rarely accounts for the cost of getting there. As philosopher Bertrand Russell once noted, “One of the symptoms of an approaching nervous breakdown is the belief that one’s work is terribly important.”The commute quietly feeds that cycle. Recognising it is the first step toward protecting health.Medical experts consultedThis article includes expert inputs shared with TOI Health by:Dr Keshava R, HOD & Consultant – Interventional Cardiology, Manipal Hospital Old Airport Road.Inputs were used to explain how daily commuting impacts the heart, lungs, and brain, and to highlight why this routine exposure can become a significant source of stress for overall health.
