Sunburn vs Sun Poisoning: Know the Difference and Stay Safe

Nothing beats a sun-filled Texas weekend at the pool or lake – warm sunshine, laughter, and quality family time. It’s easy to relax and soak it all in and still be smart about what your skin might need.

Knowing the difference between a regular sunburn and more serious sun poisoning can keep everyone smiling – and healthier. Let’s talk through what to look for, what to do, and when to head to an ER that’s open 24/7, like Physicians Premier.

What is a Sunburn

Sunburn happens when your skin gets too much UV exposure. It often shows up as redness, warmth, soreness, and sometimes peeling. Most cases are mild and heal within a few days with proper care, like staying hydrated, using cool compresses, and applying sunscreen regularly to help avoid future burns.

What is Sun Poisoning

Sun poisoning isn’t an official medical diagnosis. It describes a severe sunburn that comes with systemic symptoms like fever, chills, nausea, dizziness, swelling, or blisters.

Dermatologists describe it as a strong immune system overreaction to concentrated UV exposure, leading to flu-like symptoms and dehydration.

According to Harvard Health, sun poisoning refers to a more extreme form of sunburn that produces intense skin damage, such as rash, blisters, swelling, and fever. The CDC also confirms that serious sunburns can include systemic symptoms like headache, fever, chills, nausea, or vomiting.

How Common Are These Conditions

• About 34,000 people go to the ER each year in the U.S. because of serious sunburns.
• Summer drives demand on ERs – about 25 percent of U.S. ER visits happen from May through September.
• While most sunburns are mild, thousands of Americans end up in ERs each year with severe burns or sun poisoning symptoms – it’s part of almost 28% of all emergency visits related to injuries or poisonings.

These numbers show how common sun-related injuries are, especially during fun outdoor months.

Signs to Watch For

Sunburn

• Red, tender skin that feels hot
• Mild to moderate swelling or peeling
• Worst symptoms 24–36 hours after exposure

Sun Poisoning

• Large blisters and intense swelling
• Fever, chills, headache, nausea, dizziness
• Fast or irregular heartbeat
• Confusion, extreme fatigue, or signs of dehydration

If symptoms go deeper than skin, like fever or vomiting, it’s time to think about ER care.

When to Treat at Home

For mild sunburn, comfort measures often work well:

• Get out of the sun and into the shade
• Take cool baths or showers
• Hydrate often with water or electrolytes
• Apply aloe or moisturizer
• Use ibuprofen or acetaminophen for pain relief

But skip scrubbing, popping blisters, or toughing it out. Your skin needs gentle care.

When to Seek ER Care

Sunburn: Treat at Home Unless:

• Blisters cover a large area (over 20 % of your body)
• You have severe swelling, intense pain, chills, or fever higher than 102°F (39 °C)
• You’re dizzy, dehydrated, confused, or vomiting

Sun Poisoning: Go to the ER If You Have:

• High fever, chills, or flu-like symptoms
• Blisters, swollen face, or eyes
• Dizziness, fainting, fast heartbeat
• Confusion or signs of dehydration

Professional care can include IV fluids, stronger pain meds, infection prevention, and monitoring, helping you skip complications and recover stronger.

Why Quick Response Matters

Severe UV damage can cause issues beyond your skin. If your body starts overheating or gets dehydrated, you might end up in the hospital. ER care can prevent complications like infection, heat exhaustion, organ strain, or hospitalization. Treating these early at an ER can stop things from getting worse and help you bounce back quicker.

Prevention Tips to Stay Safe in the Sun

• Plan ahead – Use the UV index and avoid peak sun between 10 am – 4 pm.
• Choose the right sunscreen – Broad-spectrum SPF 30+, water-resistant, reapplied every 2 hours or after swimming.
• Dress smart – Wear hats, sunglasses, and tightly woven clothes for extra protection.
• Stay hydrated – Drink water or electrolyte drinks before, during, and after sun exposure.
• Cool it down – After sun time, use cool showers or compresses and moisturize with aloe or lotions.
• Spot the warning signs – Don’t ignore blisters, fever, or whole-body symptoms; those are serious red flags.
