“During winters skin dries up and superficial skin starts pealing. And with the sudden increase in the temperature, perspiration helps fungus (present in woollen clothes) proliferate, leading to skin infections like dermatitis, boils and itching. So one should avoid wearing woollen cloths,” said Dr Jayesh Lele, a general practitioner in Malad.

“I still carry my woollen sweater to work as it is cold in the morning hours. However, as the day progresses it becomes very hot and sultry, and this sudden change just takes toll over my health,” said Meera Naidu, a Virar resident.

Due to the presence of dust in the air, a lot of cases of upper respiratory tract infection are also being reported.

“The fog that one sees in the morning has a lot of dust that leads to tonsillitis, pharyngitis or any other related disease,” said Dr Prakesh Kawli, a practicing physician at Shivaji Park, who says he has seen 20 to 30 per cent rise in cases of viral fever and influenza in the past couple of days. “Morning joggers should cover their faces to avoid dust entering through the respiratory tract,” Dr Kawli added.
