It is unhealthy to walk in fog?

By itself, fog does not contain harmful substances and generally does not cause health problems for healthy individuals.

However, several sources indicate that fog can trap pollutants and allergens near the ground due to low air movement, which may exacerbate respiratory issues for sensitive individuals or those with pre-existing conditions such as asthma or allergies.onlymyhealth.comonlymyhealth.comFoggy Morning: Here Are Some Precautions To Take Before Stepping Outside Additionally, fog mixed with pollution forms smog, which is harmful to health.
