Morning walks have long been a favourite way to stay healthy for many Indians. pulmonologist Dr Tarang Kulkarni, consultant at Jupiter Hospital, Thane, believes that pollution levels may change how safe outdoor exercise is While it can support physical and mental well-being.
“Stepping outdoors early in the morning does not automatically mean breathing cleaner air. Air quality can vary throughout the day.”
“Checking AQI and making informed choices about timing, routes and intensity can help people stay active while reducing exposure,” he shared with HT Lifestyle.
1. Check AQI before stepping out
Dr Kulkarni noted that he was not making a case for people to abandon their morning walks. Rather, he listed eight points to keep in mind before going out in the mornings. The pulmonologist believes it is best to make a habit of checking the local air quality index (AQI) rather than assuming that early morning air is cleaner. “Checking the AQI before leaving home can help you decide whether outdoor exercise is appropriate that day. Many people automatically opt for walks between five and six in the morning, believing that the air is cleaner at that time. However, Dr Kulkarni cautioned that pollution can get trapped close to the ground during temperature inversion and low-wind conditions. “Instead of following a fixed schedule, check local air quality at the time you plan to exercise and choose a cleaner time of day. The goal should be to walk when outdoor conditions are more suitable, rather than assuming that a particular hour is always better,” he noted. The route that one chooses for their morning walk also matters. The pulmonologist suggested avoiding roads with heavy vehicular traffic, traffic junctions, bus depots, construction sites and areas with visible dust or smoke. Instead, he preferred parks and walking tracks located away from major roads. “However, remember that trees alone do not guarantee clean air. Choosing a route with less direct exposure to traffic and visible pollution is important,” he noted. When pollution levels are elevated, Dr Kulkarni advised avoiding brisk walking, jogging, running or other strenuous outdoor activity. People with asthma or chronic obstructive pulmonary disease (COPD) need to be particularly cautious on high-pollution days. Dr Kulkarni’s advice: “Avoid outdoor exercise when pollution levels are high, follow your prescribed medication plan and carry your prescribed rescue inhaler, if applicable. “Increased coughing, wheezing, chest tightness or breathlessness should not be ignored. These symptoms may indicate that outdoor conditions are affecting your breathing,” he added. Children and older adults may be more vulnerable to the effects of air pollution, and one should be particularly cautious about taking them for outdoor walks or exercise when pollution levels are high. If a person develops unusual coughing, wheezing, chest tightness or breathlessness during a walk, it is best they stop exercising and move to a cleaner indoor environment. “Severe breathlessness or chest pain warrants urgent medical attention. “Continuing to exercise despite these symptoms is not advisable. Paying attention to how your body responds is an important part of making outdoor activity safer,” he added. Dr Kulkarni highlighted that a poor AQI does not mean that physical activity has to stop for the day. Indoor walking, treadmill exercise, stationary cycling or other suitable indoor physical activities can serve as alternatives in such situations.

Therefore, continuing a strenuous workout outdoors when pollution levels are high may increase exposure.
“If the AQI is poor (201–300) or worse, consider shifting your walk indoors, particularly if you belong to a high-risk group,” he stated. “Reduce the duration and intensity of your walk or move your exercise indoors,” he stated, explaining, “During exercise, breathing increases, which means a greater volume of polluted air enters the lungs. “Check the AQI before planning outdoor activities and consider indoor alternatives when air quality is poor,” shared the pulmonologist. “Seek medical evaluation if symptoms persist or worsen,” suggested Dr Kulkarni.
