To quickly relieve hives, you can try methods such as cold compresses, medication, and avoiding irritants. The specific methods are described below:

1. Apply cold compress to soothe.

Wrap an ice pack or a cloth soaked in cold water in a towel and gently apply it to the itchy, red, and swollen area for about 10 minutes each time. The low temperature can temporarily constrict blood vessels, reducing itching and swelling.
2. Use of medication
Under the guidance of a doctor or pharmacist, oral antihistamines (such as loratadine) may be considered, as these medications can help relieve allergic reactions. Topical ointments such as calamine lotion can also relieve itching.
3. Avoid stimulation
Wear loose cotton clothing to reduce friction; avoid using excessively hot water when bathing and avoid using harsh soaps; temporarily stay away from foods (such as seafood and spicy foods) and environments (such as pollen and pet dander) that may aggravate symptoms.
4. Record the triggers.
Paying attention to your diet, activities, or contacts before an outbreak of hives can help identify potential triggers and facilitate subsequent prevention.
If symptoms persist or are accompanied by severe conditions such as difficulty breathing, please seek medical attention immediately. Maintaining a relaxed mood and regular sleep schedule can also help reduce the frequency of attacks.
