Dr. Doanh Nguyen, md, faaaai answered

Specializes in Allergy and Immunology

Hives: If your hives is less than 6 weeks, most of the time, we cannot identify what causes it. Chronic hives more than 6 weeks need to be worked up. Hives at night might be caused by cold temperature or allergies to the allergens you expose to more often at night like dust mites, animal danders if you are allergic to those.
