[header] How to deal with cold urticaria [title] Avoid cold weather conditions. [step] If you've noticed that your skin develops an itchy rash when it's chilly, then the best precaution is to not expose yourself to cold weather conditions. This can be a challenge in northern climates, but making sure you're always dressed warmly during winter months can help a great deal. 
Layer your clothes and try to wear natural breathable fibers, such as cotton and wool. Always wear gloves and don't forget to cover your neck and face with a scarf.
