When I take a shower and wet my hair, my sinus seems to drain really bad
. This I believe is the source of my bad
2. The same happens when I am out in the cold. When I dress warm, the drainage and the bad breath are better by atleast by 60% - 70%.
So, my question is,
1. Is there any relation between wetting my hair and my sinus running and bad breath?
2. How is the cold weather affecting my sinus and how is dressing up warmly helping?
Thanks for your help.
