What happens when urticaria breaks out at night?

Hives at night may be caused by exposure to allergens, less external interference, reduced hormone secretion, etc.

1. Patients exposed to allergens

need to touch pillows, sheets, quilts and other items during sleep at night. If there are animal hair, mites and other sensitive substances mixed on them, it may cause urticaria attacks.

2. Patients with less external interference at night

will be less disturbed, and their sensitivity may increase, thus making them more prone to urticaria attacks.

3. Hormone secretion decreases at night.

Hormone levels in the body may decrease, which may lead to reduced inhibition of allergic medium release, thus causing urticaria attacks.
