How to Treat Sun Poisoning at Home

Most cases of sun poisoning can be treated at home with a combination of cooling measures, hydration, over-the-counter pain relief, and skin protection. Sun poisoning goes beyond an ordinary sunburn: it involves systemic symptoms like nausea, fever, chills, and blistering alongside the expected redness and pain. Recovery typically takes longer than a standard sunburn, but the right home care can significantly reduce discomfort and speed healing.

Sun Poisoning vs. a Regular Sunburn

A mild to moderate sunburn causes redness, pain, and skin that feels hot to the touch. Those symptoms usually start fading after about three days. Sun poisoning lasts longer and hits harder. Beyond the skin damage, it triggers whole-body reactions: blisters, severe itching or pain, headache, nausea and vomiting, fever and chills, dizziness, dehydration, fatigue, and a rapid heartbeat.

Recognizing the difference matters because it changes how aggressively you need to treat it. If you just have pink, tender skin without any systemic symptoms, standard sunburn care is enough. Once you’re dealing with blisters, nausea, or fever, you need to be more deliberate about hydration, pain management, and monitoring for worsening signs.

Cool the Skin Down First

Your first priority is bringing skin temperature down. Take a cool (not cold) bath or apply cool, damp compresses to the burned areas. You can also soak in a bath with colloidal oatmeal or Epsom salts, both of which help soothe inflamed skin. Keep baths brief, around 10 to 15 minutes, and pat your skin dry gently rather than rubbing.

Do not apply ice directly to sunburned skin. Ice can cause frostbite on already damaged tissue, converting one injury into another.

Topical Treatments That Help

Once your skin is cool and dry, apply aloe vera gel to the affected areas. Pure aloe is best, since products with added fragrances or alcohol can further irritate the burn. Calamine lotion works well for intense itching. For more significant inflammation, a nonprescription 1% hydrocortisone cream applied three times a day for up to three days can reduce swelling and discomfort.

Gel-based pain relievers that you rub directly onto the skin are another option, particularly for localized areas of intense pain. These can complement oral pain relievers without the additional systemic dose.

What Not to Put on Your Skin

Antibiotic ointments can cause a secondary skin rash on irritated tissue, especially if you’ve never used them before. Rubbing alcohol, hydrogen peroxide, and other harsh chemicals will strip moisture from already damaged skin and worsen the burn. Butter, honey, mustard, and other home remedies from older folk traditions offer no benefit and can trap heat or introduce bacteria. Stick with the treatments listed above.

Take Pain Relievers Early

Start an over-the-counter pain reliever as soon as possible after the burn. Ibuprofen is the strongest option for sun poisoning because it reduces both pain and inflammation simultaneously. Acetaminophen will help with pain and fever but won’t address the inflammatory component. Take either one according to the package directions, and start before the pain peaks rather than waiting until it becomes severe.

Hydrate Aggressively

Sun poisoning pulls fluid from your body in two ways: through the damaged skin itself and through the systemic response (fever, sweating, sometimes vomiting). You need to take in more fluid than you’re losing, and plain water alone may not be enough. Sports drinks help restore electrolytes and salt balance alongside fluid. For children, an electrolyte solution like Pedialyte is a better choice than homemade salt-water mixtures.

Avoid coffee, caffeinated soda, tea, and alcohol during recovery. All of these promote fluid loss and work against your rehydration efforts. If you’re experiencing vomiting, take small, frequent sips rather than large amounts at once.

Protect Blisters From Infection

Blisters are your body’s way of protecting the damaged tissue underneath. Do not pop, peel, or drain them. Broken blisters increase your risk of infection, scarring, and permanent changes to skin color. If a blister breaks on its own, gently clean the area with mild soap and water, then cover it loosely with a non-stick bandage.

Keep blistered skin out of the sun entirely while it heals. Wear loose, soft clothing over affected areas. Tight or rough fabrics will irritate blisters and slow recovery.

What to Expect During Recovery

Sun poisoning symptoms last noticeably longer than a standard sunburn. While a typical sunburn starts improving around day three, sun poisoning can take a week or more before the systemic symptoms fully resolve. The skin itself may peel for several days after the pain subsides. Resist the urge to pull peeling skin, as the new skin beneath is fragile and easily damaged.

During recovery, stay out of the sun completely. Even indirect UV exposure can worsen inflammation in already compromised skin. If you must go outside, cover the burned areas with clothing and stay in the shade.

A Related Condition: Sun Allergy Rash

Some people develop a rash from sun exposure that isn’t a burn at all. Polymorphous light eruption is an immune reaction to UV light that produces an itchy, bumpy rash, often on the chest, arms, or legs. It typically resolves on its own within about 10 days. If the itching is severe, a 1% hydrocortisone cream can help. This condition tends to recur with sun exposure but often improves over a season as the skin gradually adapts.

When Home Treatment Isn’t Enough

Home care works for most cases, but certain symptoms signal that you need medical attention. Seek emergency care if you experience confusion, severe dehydration (very dark urine, dizziness when standing, no urination for several hours), a high fever that doesn’t respond to pain relievers, or widespread blistering that covers a large area of your body. If you’ve been treating at home for several days and still have extreme pain and spreading blisters, it’s time for professional evaluation. These signs can indicate a burn deep enough to require wound care beyond what’s practical at home.
