How to deal with cold urticaria
Avoid cold weather conditions.
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.
