In many areas of Delhi and NCR, the Air Quality Index (AQI) has exceeded the 400 mark. Questions arise about how dangerous such a level of pollution is for health and whether one should go for a walk. Experts explain which groups of people are at the highest risk.
Dr. Ankit Bhatia from the Respiratory Medicine department of Yashoda Medical Center explained that when the AQI is above 400, long walks in the fresh air should not be planned. He emphasized that the problem is not only the time spent in polluted air but also the duration of physical exercise outdoors. Prolonged exposure to such high levels of pollution can negatively affect the lungs, so it is recommended to refrain from long walks outdoors at this time. Going outside, both in the morning and in the evening, can worsen health conditions. Instead, one should try to engage in walking and physical exercises indoors. Going for a walk is permissible only in cases of extreme necessity.
A mask must be used
Dr. Ankit advised wearing a mask if one needs to go out for any errands. An N95 respirator that fits tightly can prevent fine PM2.5 particles from entering the lungs. However, the effectiveness of the mask directly depends on how well it seals against the nose and mouth; any gap can allow polluted air to enter. Furthermore, it is advisable to avoid using cloth or loose surgical masks.
Who is in the high-risk group
Children, the elderly, and those suffering from asthma, COPD, or heart diseases should exercise extra caution. On days with very high pollution levels, it is best to take walks indoors. This approach allows people to remain active without placing excessive strain on the respiratory system.
