Hives

What are hives?

Hives are sudden, itchy, red bumps that develop in response to an allergen (something that causes an allergic reaction). While hives, called urticaria, look similar to bug bites, they usually disappear more quickly.

These rashes eventually disappear but can be uncomfortable and sometimes last for days or weeks. Hives keep coming back or become chronic (ongoing) in some cases.

Hives are fiercely itchy. Scratching them can worsen symptoms, leading to more irritation, swelling, and even new hives. Finding a treatment that works for you is essential to keeping hives at bay.

What triggers hives?

Hives occur when your immune system overreacts to a trigger and releases histamine, a chemical causing the skin to swell, itch, and form red welts. Histamine is part of your body's defense system, but if you have an allergy, it responds to harmless substances as threats. 

Sometimes, the cause is obvious, like an allergic reaction to food or medication, but hives can also appear without a reason. Common triggers include:

• Food allergies like nuts, shellfish, eggs, and dairy
• Medications, including antibiotics and pain relievers
• Insect stings or bites from bees, mosquitoes, or other insects
• Environmental factors like heat, cold, sunlight, or pressure on the skin
• Infections, illnesses, or even stress

Identifying what’s behind your outbreaks can help you manage symptoms and prevent future flare-ups.

Can I treat hives at home?

You can relieve discomfort from hives with home remedies that help soothe itching and stinging. But it’s important to learn why you have hives in the first place, or they might come back. Some ways to treat hives at home include:

• Take over-the-counter antihistamines to reduce itching and swelling
• Apply a cold compress to soothe irritated skin
• Wear loose, breathable clothing to prevent further irritation
• Use fragrance-free lotions or creams to keep skin calm
• Avoid hot showers or baths, which can irritate hives
• Identify and avoid potential triggers, like certain foods or medications
• Practice stress management techniques

You should also avoid scratching hives; it can irritate and injure them.
