You’re at the beach or maybe just out gardening. The sun feels good until it doesn't. Then, suddenly, your skin isn't just pink—it's angry. It’s deep purple or bright red, and you start feeling like you’ve caught a flu you didn't ask for. That’s the threshold. You’ve crossed from a "oops, I forgot the SPF" moment into the realm of polymorphic light eruption or, more commonly, sun poisoning.
It hurts.
Most people think how to help sun poisoning is just about slathering on some green goo from the drugstore, but honestly, it’s a whole-body inflammatory response. It’s your immune system losing its mind because the UV radiation literally damaged your cellular DNA.
What Sun Poisoning Actually Is (And What It Isn't)
Let’s get one thing straight: "Sun poisoning" isn't a medical term you'll find in a textbook, but doctors like those at the Mayo Clinic use it to describe severe phototoxicity or a systemic allergic reaction to the sun. It’s not actually "poison" in the sense of arsenic or hemlock. It's more like your body is having a massive, panicked meltdown.
You’ll know it’s happened when the standard sting of a burn is accompanied by a fever that makes your teeth chatter. Or maybe you see tiny, fluid-filled blisters that look like a heat rash on steroids. Sometimes it’s a "solar urticaria," which is basically hives triggered by light. If you’re dizzy or nauseated, you’re not just tired from the heat. Your body is struggling to manage the inflammation.

Immediate Steps: How to Help Sun Poisoning Right Now
Stop. Get out of the sun. This seems obvious, but people often try to "tough it out" under an umbrella. Umbrellas don't block reflected UV from the sand or water. You need four walls and a ceiling.
Once you're inside, hydration is your new full-time job. When your skin is scorched, it draws fluid away from the rest of your body to try and heal the barrier. This leads to rapid dehydration. Drink water. Not soda. Not a beer. Electrolyte drinks like Pedialyte or even a simple Gatorade can help, but plain water is the gold standard.
The Cold Compress Trick
Don't use ice. Seriously. Putting ice directly on a sun-poisoned area can cause further tissue damage because the skin is already compromised and fragile. Instead, use cool—not freezing—water.
- Soak a clean, soft cloth in cool water.
- Wring it out so it's not dripping everywhere.
- Gently lay it over the affected area for 10 to 15 minutes.
- Repeat this several times a day.
If you have a large area affected, a cool bath is a godsend. Adding a cup of colloidal oatmeal (like Aveeno or just finely ground oats) can calm the itch. It's an old-school remedy that actually has science behind it; the avenanthramides in oats are potent anti-inflammatories.
Why Your Skin Is Blistering
Blisters are your body's "Keep Out" signs. They are sterile environments designed to protect the raw, new skin underneath. Whatever you do, don't pop them. I know it's tempting. I know they look weird. But popping them is an express ticket to a secondary staph infection.
If a blister pops on its own, don't panic. Wash the area with very mild, fragrance-free soap. Apply a tiny bit of antibiotic ointment and cover it loosely with a non-stick bandage. You want the skin to breathe, but you don't want your shirt rubbing against raw nerves.
Meds That Actually Work
When you're looking for how to help sun poisoning, the medicine cabinet is usually the first stop. Over-the-counter pain relievers like ibuprofen (Advil, Motrin) or naproxen (Aleve) are better than acetaminophen (Tylenol) here. Why? Because they are NSAIDs—non-steroidal anti-inflammatory drugs. They don't just kill the pain; they actually fight the "fire" in your tissues.
For the itching—which can be maddening, a sensation often called "Hell's Itch"—an oral antihistamine like Benadryl (diphenhydramine) or Claritin (loratadine) can take the edge off. Topical hydrocortisone cream (1%) can also help, but avoid anything with "caine" in the name, like benzocaine or lidocaine, unless a doctor told you to use it. These can sometimes irritate sun-poisoned skin even further or cause an allergic reaction.
The Role of Medications You’re Already Taking
Here is something most people miss: Your daily meds might be the reason you got sun poisoning in the first place. This is called "photosensitivity."
- Antibiotics: Specifically tetracyclines or doxycycline (often used for acne or Lyme disease).
- Retinoids: If you use Retin-A or Accutane, your skin is basically a sponge for UV.
- Diuretics: Some blood pressure meds make you burn in minutes.
- NSAIDs: Ironically, the same meds that help the burn can sometimes make you more sensitive to the sun beforehand.
If you’re on these, your "safe" time in the sun might only be 10 minutes instead of two hours.
When to Call a Doctor (The "No-Joke" List)
Sometimes, home remedies aren't enough. Sun poisoning can escalate into heat stroke or a severe skin infection. You need to head to an urgent care or ER if you experience:
- A fever over 102°F (39°C).
- Confusion or "brain fog."
- Fainting or extreme dizziness when you stand up.
- Large areas of blistering (like your entire back or chest).
- Yellow drainage or red streaks coming from a blister (signs of infection).
- Inability to keep fluids down.
Doctors might prescribe a short course of oral steroids like prednisone to shut down the systemic inflammation. They might also give you IV fluids if your blood pressure is tanking from dehydration. It’s better to go and be told "you're fine" than to stay home and risk a major complication.
Natural Remedies That Aren't Total B.S.
Aloe vera is the classic. It's great. But check the label. If the second ingredient is "Alcohol Denat" or "Fragrance," put it back. Alcohol dries out the skin, which is the last thing you want. You want 100% pure aloe gel, preferably kept in the fridge.
Another weirdly effective one? Witch hazel. It’s an astringent but also contains tannins that can reduce swelling. Pat it on gently with a cotton ball.
Apple cider vinegar is often touted online, but be careful. For some, the acetic acid helps balance the skin's pH. For others, it stings like crazy. If you try it, dilute it heavily—one part vinegar to ten parts water. If it hurts, wash it off immediately.
The Long Road to Recovery
Your skin is going to peel. It’s inevitable. This is your body's way of getting rid of the damaged cells that could potentially turn cancerous. Do not peel it off prematurely. Let it flake off in its own time.
Keep the area moisturized with a thick, bland cream like CeraVe or Eucerin. Avoid anything with heavy scents or "anti-aging" acids (like glycolic or salicylic acid) for at least two weeks. Your new skin is incredibly thin and vulnerable. Even a few minutes of sun exposure on that "new" skin can cause a repeat performance of the poisoning.
Real Talk on Prevention
You’ve heard it all before, but let’s be real. Most people apply about half the amount of sunscreen they actually need. You need a full shot glass worth for your body. And you have to reapply every 90 minutes.

If you’ve had sun poisoning once, you are more likely to get it again. Your skin might remain hypersensitive for weeks or even months. Invest in UPF (Ultraviolet Protection Factor) clothing. A UPF 50+ shirt is better than any sunscreen because it doesn't wash off and you can't "miss a spot."
Actionable Steps for Healing
If you are currently dealing with the aftermath of too much sun, follow this protocol to get back on your feet:
Step 1: Cool Down and Hydrate
Immediately move to a dark, air-conditioned room. Drink 16 ounces of water or an electrolyte solution. Take a cool (not cold) shower or apply wet compresses to the most painful areas.
Step 2: Manage Inflammation
Take an over-the-counter NSAID like ibuprofen if your stomach allows it. This targets the internal swelling that causes the "flu-like" feeling.
Step 3: Support the Skin Barrier
Apply pure aloe vera or a fragrance-free moisturizer while your skin is still damp from the shower. This traps the moisture in.
Step 4: Monitor and Protect
Check your temperature every few hours. If you see blisters, do not touch them. Wear loose, cotton clothing that doesn't rub. If you must go outside, cover every inch of the affected skin with physical barriers (clothing), as sunscreen can irritate the open "wounds" of sun poisoning.
Step 5: Review Your Meds
Check your prescriptions for "photosensitivity" warnings. If you find one, stay completely out of the sun until you've finished the medication and the sun poisoning has fully cleared.
Healing from this takes time—usually 7 to 10 days for the worst symptoms to subside. Be patient with your body; it’s doing a lot of heavy lifting right now to repair the damage.
