The term sounds alarming, but sun poisoning is essentially a severe, systemic reaction to too much UV exposure — the skin is burned, and your body responds with symptoms beyond simple redness. You might feel nauseated, feverish, dizzy, or chilled, and the affected skin may blister. The treatment plan that follows tackles both the burned skin and those whole-body symptoms, and knowing when to get medical help matters just as much as home care.
Here’s the straightforward sequence that dermatologists and health organizations recommend, from the first minutes after you come inside to the days of recovery that follow.
Start With Immediate Cooling and Hydration
The first hours after sun poisoning set the tone for recovery. Get out of the sun entirely and stay out until your skin has healed — any additional exposure will only deepen the damage.
- Take a cool shower or bath, or apply cool compresses with a damp towel. Cool the skin for about 10 minutes, several times a day.
- Never use ice or ice packs directly on sunburned skin — the extreme cold can damage already-injured tissue.
- Skip alcohol, which dehydrates you further.
Your skin is inflamed and hot to the touch because blood vessels have dilated to heal the burn; cooling it slows that process and eases the stinging sensation.
Once you’re cool and hydrated, over-the-counter remedies handle the pain and the skin’s raw feeling. The Cleveland Clinic’s guidance on sun poisoning lists several effective options:
- Apply aloe vera gel, calamine lotion, or an unperfumed moisturizer. Refrigerating the product first adds a welcome cooling effect.
- For mild to moderate burns, nonprescription 1% hydrocortisone cream applied three times a day for up to three days can cut inflammation.
Skip anything that could irritate the burn further: products containing alcohol sting and dry the skin, and creams with -caine ingredients like benzocaine or lidocaine can trigger allergies and worsen the burn.
If the blistered, painful skin is preventing you from sleeping or going about your day, our tested roundup of the best creams for sun poisoning relief compares the aloe-based and hydrocortisone options that dermatologists most often recommend.
When Sun Poisoning Needs Urgent Medical Care
Sun poisoning can push the body past what home care can manage. The Mayo Clinic advises seeking medical attention for a sunburn accompanied by any of these warning signs:
- Nausea, chills, fever, or dizziness
- Generalized weakness, confusion, or faintness
- Severe swelling, or signs of dehydration like dark urine and extreme thirst
- A burn covering a large portion of the body
- No improvement after a few days, or any sign of infection such as pus or increasing redness
Severe cases may require IV fluids, prescription pain medication, steroid creams or pills, or topical antibiotics — treatments you can’t replicate at home. When in doubt, a call to your doctor beats waiting it out.
FAQs
How long does sun poisoning take to heal?
Can you get sun poisoning without a visible burn?
It’s possible to feel the systemic symptoms — headache, fever, chills, nausea — with only modest skin redness, especially if you’re fair-skinned and were exposed for a long stretch. Treat the whole-body symptoms as seriously as the skin reaction and seek care if they worsen.
Is sun poisoning the same as sunstroke?
No. Sun poisoning is a severe sunburn reaction affecting the skin and causing flu-like symptoms. Sunstroke, or heatstroke, is a medical emergency where the body’s core temperature spikes dangerously high and the sweating mechanism fails. Heatstroke requires emergency treatment immediately.
