Adjustment to Changing Weather

My niece is having some uncomfortable moments whenever it’s too cold or too hot, she seems to have some hardship in adjusting to extreme weather. Just now she’s sneezing and starting to have coughs because she was exposed to cold air at night when she goes home after work. I told her that it’s better to stay at home for few days until she’s well. Now she’s slowly adjusting to changing weather and was happy to find the best allergy relief whenever she has some skin allergy all over her face and body.
