:Cryophobia:

It's a fear of extremely cold temperature and is associated with frigophobia, which is a fear of cold in general. Cryophobia can be caused by widely known stories about frostbite, hypothermia, or tragedies on mountain peaks. It most often occurs in people living in areas that regularly experience winter – to be more precise, in high latitudes. To avoid coldness, sufferers may live in warm climates and dress more warmly than they should.
