How to Treat Sunburn Fast + When to See a Doctor

How to treat sunburn fast + when to see a doctor

A day at the beach, pool, park or backyard can be one of the best parts of summer until you notice your skin turning red. Sunburn is more than a temporary burn. It is a sign that ultraviolet (UV) rays have damaged your skin. Crystal Run Healthcare’s sun safety guidance reminds patients to protect their skin even on cloudy days and to practice sun safety all year.
The good news is that many mild sunburns can be treated at home. Here is what to do right away, what to avoid and when it is time to get medical care.

What is sunburn?

Sunburn happens when your skin gets more UV light than it can handle. This damage can cause redness, pain, warmth, swelling and sometimes blistering. Symptoms may start within a few hours after sun exposure and can get worse the next day.
Sunburn is not limited to beach days. It can happen during sports, yard work, walks, camps and other outdoor activities. That’s why Crystal Run Healthcare encourages patients to practice sun safety during everyday summer routines — not just on hot days.

How to treat sunburn at home

For mild to moderate sunburn, home care is often enough to ease pain and support healing.

Start by cooling the skin. A cool bath or shower can help. You can also place a clean towel with cool water on the area for short periods during the day. Avoid putting ice directly on your skin.

Next, keep your skin moisturized. Aloe vera or a gentle moisturizer may help soothe your skin and reduce dryness as it heals.

Drink extra water after a sunburn, especially if you have been out in the heat. Over-the-counter pain relievers may also help if you use them as directed.

If your skin starts to peel after a few days, that is part of healing. Keep using moisturizer and do not pick at peeling skin. If blisters form, try not to break them.

What not to do after a sunburn

A few common mistakes can make sunburn feel worse.

Don’t apply ice directly to your skin, and don’t pick or pop blisters. If a blister opens on its own, keep the area clean and protected.
Most importantly, avoid more sun exposure while your skin heals. Cover up, seek shade or stay indoors when possible until the area feels better.

How long does sunburn last?

Many mild sunburns get better over several days. If your symptoms get worse instead of better, or if blistering or strong pain develops, it may be time to seek medical care.

Sunburn in children: what parents should know

Children can get sunburned quickly, so prevention is very important. If your child has red, painful or warm skin after being outdoors, move them out of the sun, cool the skin, offer fluids and watch symptoms closely.

If your child develops blistering, fever, signs of dehydration or worse discomfort, contact your child’s pediatrician or seek medical care. Severe sunburn needs prompt attention.

When to see a doctor for sunburn

While many sunburns can be managed at home, there are signs that it’s time to seek medical care.

Get medical attention if you or your child develops: 

• large blisters
• severe pain
• Fever or chills
• Dehydration or dizziness 

If symptoms get worse instead of better, it’s important to see a doctor. Eye symptoms or signs of infection also need prompt evaluation.

How to help prevent sunburn

The best sunburn treatment is prevention. The American Academy of Dermatology recommends wearing water-resistant, broad-spectrum sunscreen with SPF 30 or higher. Put it on before sun exposure and reapply every two hours, or sooner after swimming. Protective clothing, wide-brim hats, sunglasses with UVA and UVB protection and shade during peak sun hours are also important. Sun rays are strongest between 10 a.m. and 4 p.m.

Approved sun safety guidance from the EPA (U.S. Environmental Protection Agency) and dermatology experts also recommends checking the UV index, choosing shade when possible and remembering that sun protection matters on everyday outings too.

If you spend time outdoors often — especially in summer — sun protection should be part of your routine, just like staying hydrated or wearing a seat belt.

Don’t forget your eyes

Sun safety is not just about your skin. Wearing sunglasses with UV protection is also an important way to protect your eyes during extended time outdoors.
