Delhi air pollution has taken a toll on everyone residing in or near Delhi-NCR’s mental and physical health. This sudden and hazardous decline in air quality leads to health risks, including respiratory problems, heart diseases, and in severe cases, premature death. As the winter season sets in, air pollution may worsen due to smog. This increase in pollution levels raises concerns, particularly for people with outdoor exercise routines like morning walks. Hence, we often opt for masks as a precautionary measure to keep ourselves safe from pollution. But are they really safe?
