A woman who is "allergic to winter" has to wear a face mask whenever she goes outside in case a slight drop in temperature causes a fatal reaction.
Max Fisher, 23, suffers from cold-induced urticaria which can kill sufferers in extreme cases. The allergic reaction is similar to people who go into anaphylactic shock if they suffer a bee sting.
Whenever Max inhales cold air or drinks a cool drink she comes out in red, itchy hives. The pharmacology graduate is raising awareness about the condition ahead of the expected cold snap.
She also wants to raise awareness after she suffered abuse in the street from yobs because she was wearing a face mask.
