Did you spend a little too long in the sun—and now your skin is more than just red? If you’re feeling sick, dizzy, or blistered after sun exposure, you might be experiencing sun poisoning.

What Is Sun Poisoning? 

Despite the name, sun poisoning doesn’t involve actual poison. It’s a severe reaction to too much ultraviolet (UV) radiation—typically from extended sun exposure without proper protection. It’s sometimes called polymorphic light eruption or severe sunburn, and it goes beyond a typical sunburn in both symptoms and seriousness.

Common Causes: 

  • Spending multiple hours in direct sunlight
  • Forgetting sunscreen or using a low SPF
  • Being near water, snow, or sand (which reflect UV rays)
  • Having fair or sensitive skin

 Sun Poisoning Symptoms 

Sun poisoning can come on suddenly after intense sun exposure. Symptoms may include:

  • Severe sunburn with red, inflamed, or blistering skin
  • Fever and chills
  • Nausea or vomiting
  • Headache or dizziness
  • Dehydration
  • Fainting or confusion

Some people also develop a rash or hives. These symptoms can range from uncomfortable to dangerous—so it’s important to monitor your condition closely.

Sun Poisoning vs. Heat Rash: What’s the Difference? 

Sun Poisoning Heat Rash
Caused by UV exposure  Caused by trapped sweat 
Appears on sun-exposed skin  Appears under clothing or in skin folds 
Blisters, fever, nausea possible  Small red or clear bumps, no fever 
May require urgent care  Usually clears up on its own 

Heat rash is common in hot, humid conditions and usually resolves with cooling. Sun poisoning requires more caution and, in some cases, medical care. 

How Long Does Sun Poisoning Last? 

Recovery time depends on the severity: 

  • Mild cases: 2–3 days with self-care
  • Moderate cases: Up to a week
  • Severe cases: Several weeks and may require clinical treatment

If your symptoms are getting worse or not improving within a few days, don’t wait—seek medical attention. 

How to Treat Sun Poisoning 

Early treatment helps prevent complications like infection or severe dehydration. Try these first-aid steps: 

  • Get out of the sun immediately 
  • Cool the skin with cool water or compresses 
  • Apply aloe vera, antibiotic cream, or steroid ointments 
  • Drink plenty of fluids to rehydrate 
  • Take over-the-counter pain relievers if needed 

When to Seek Urgent Care 

You should seek medical treatment right away if: 

  • You develop fever, vomiting, or confusion
  • Your skin is severely blistered or swollen
  • You feel faint, dizzy, or dehydrated
