My commute this morning was in 31 degree F temps. I started out with my Under Armour hood and covered my mouth, ears and most of my head. Could not cover my nose because my glasses fog over. The area around my eyes was fine because of my glasses. But under my glasses the exposed areas of my cheeks were cold and hten I could not feel anything, in fact it sort of felt warm. I do not know if this is because my breath was venting out of the hood and over my cheeks or because my bod tried sending more blood to that area to keep it warm or I could not feel anything because it was numb.
I had to stop and put exchange the hood for my 3 hole "ski mask". The problem with this was on the hills that I climbed I over heated and my glasses still fogged over because of the heat coming off of my head. When I went down hill it wasn't so bad.
My commute was only about 35 min.
If the exposed areas of my face that I have with using the hood was numb, short of frost bite, which is immediate, what are the long term risks with continueing to ride this way? The exposed areas with using the mask are not nearly as much, but my glasses tend to fog over because of the heat generated when I climb the hills. Keep in mind this route is only about 35 min. long.
