How to Tell if It’s Sunburn or Sun Poisoning and What to Do

Whether you're lounging on the beach or running errands under a clear summer sky, too much sun exposure can take a toll on your skin and your entire body. While most of us are familiar with the sting of a sunburn, sun poisoning is a more severe, systemic reaction to ultraviolet (UV) overexposure that’s often misunderstood. Knowing how to recognize and prevent both can protect your health and keep your skin safe.

What’s the Difference Between Sunburn and Sun Poisoning?

Sunburn is localized skin damage caused by overexposure to UV rays. It often results in redness, discomfort, peeling, and inflammation. In contrast, sun poisoning refers to a more serious condition where sunburn is accompanied by systemic symptoms such as fever, dehydration, nausea, or confusion. Essentially, it's your body’s way of saying it’s been pushed too far.

Who’s Most at Risk?

Anyone can experience sunburn or sun poisoning, but some people are more vulnerable than others. Those at higher risk include:

1. People with fair skin, blond or red hair, and light eyes

2. Individuals at high altitudes or in areas with ozone depletion

3. Those with a family history of skin cancer

4. People who spend long periods outdoors without sun protection

5. Anyone taking certain photosensitizing medications or supplements, including:

   • Retinoids (acne treatments)

   • Antibiotics like doxycycline

   • NSAIDs like ibuprofen

   • St. John’s wort

   • Diuretics and sulfonamides

Even people with darker skin tones can experience sun damage and sun poisoning, so it’s important for everyone to take precautions regardless of skin type.

Preventing Sunburn and Sun Poisoning

Avoiding UV overexposure doesn’t mean staying indoors all summer. These strategies can help protect you while still enjoying the outdoors:

• Apply a broad-spectrum sunscreen with SPF 15 or higher to all exposed skin, including ears, neck, feet, and lips

• Reapply sunscreen every two hours, or more often if swimming or sweating

• Wear sun-protective clothing and UV-blocking sunglasses

• Use a wide-brimmed hat to protect your face and scalp

• Stay hydrated and avoid alcohol, which contributes to dehydration

• Take breaks in the shade, especially during midday hours (10 a.m. to 4 p.m.)

• Wear loose-fitting, breathable clothing if you’re active in the sun

Recognizing the Signs

Sunburn usually presents as:

• Redness and warm skin

• Pain or tenderness

• Peeling after a few days

Sun poisoning symptoms go beyond the skin and may include:

• Nausea, vomiting, or dizziness

• Headache or fatigue

• Fever or chills

• Dehydration

• Confusion or fainting

These symptoms typically appear after prolonged sun exposure, especially without adequate hydration or sun protection.

Treating Sunburn and Sun Poisoning

For mild to moderate sunburn:

• Use cool compresses on the affected skin

• Apply aloe vera gel or 1% hydrocortisone cream

• Drink extra water and avoid further sun exposure

• Take over-the-counter pain relievers like acetaminophen or ibuprofen

If blisters form, avoid popping them. Cover lightly with gauze to prevent infection.

For suspected sun poisoning:

• Sip fluids slowly to avoid nausea

• Take a cool bath or use cool packs on key areas (armpits, neck, groin)

• Rest in a shaded or air-conditioned space

• Monitor for worsening symptoms

When to Seek Medical Attention

Call your doctor or visit urgent care if you notice:

• A fever above 101°F

• Persistent vomiting or signs of dehydration

• Rapid heartbeat, pale skin, or confusion

• Severe pain that doesn’t improve with medication

• Sunburn covering more than 15% of the body

• Loss of consciousness

Sun poisoning can escalate quickly and may require IV fluids or emergency treatment, so don’t wait if symptoms seem serious.
