Sun Poisoning 101: Symptoms, Causes, Prevention, and Treatment

What to do if you have sun poisoning.

As the sun's rays beckon us outdoors, it's essential to be mindful of the potential risks associated with prolonged sun exposure. While many of us are familiar with the discomfort of sunburn, a more severe condition known as sun poisoning can pose serious health threats.

In this article, we'll delve into everything you need to know about sun poisoning, including its symptoms, causes, the distinction from sunburn, prevention strategies, and effective treatment methods.

What is Sun Poisoning?

Sun poisoning, also known as photodermatitis, is an exaggerated skin reaction to sunlight exposure. Unlike a simple sunburn, sun poisoning involves a more intense inflammatory response that can extend beyond the skin's surface. This condition is often characterized by a collection of symptoms that go beyond redness and discomfort.

Most Common Symptoms

  • Severe Sunburn: The initial symptom of sun poisoning is an intense sunburn that covers large areas of the body. The skin may appear red, swollen, and extremely sensitive to touch.
  • Blisters: In severe cases, sun poisoning can lead to the formation of painful blisters on the affected areas of the skin. These blisters can increase the risk of infection and prolong the healing process.
  • Itching and Rash: Sun poisoning may manifest as an itchy rash, accompanied by redness and inflammation. The affected skin may feel hot to the touch.
  • Headache and Dizziness: Prolonged sun exposure can lead to dehydration and heat-related symptoms such as headaches and dizziness. Severe cases may even result in nausea and vomiting.
  • Fever and Chills: Some individuals may experience systemic symptoms, including fever and chills. This indicates a more severe reaction to sun exposure that requires immediate attention.

How Does it Occur?

Sun poisoning is primarily caused by an abnormal reaction to ultraviolet (UV) radiation from the sun. However, certain factors can increase the risk of developing sun poisoning including:

Medications: Some medications, such as certain antibiotics, antihistamines, and nonsteroidal anti-inflammatory drugs (NSAIDs), can make the skin more sensitive to sunlight.

Chemicals and Fragrances: Exposure to certain chemicals, perfumes, or essential oils can trigger a phototoxic reaction when combined with sunlight, leading to sun poisoning.

Plant-induced Photosensitivity: Some plants, like giant hogweed and wild parsnip, contain compounds that make the skin highly sensitive to UV radiation. Contact with these plants can result in sun poisoning.

Sun Poisoning vs. Sunburn

While sun poisoning and sunburn both result from excessive sun exposure, they differ in severity and symptoms.

Sunburn: Sunburn is a mild to moderate skin reaction characterized by redness, tenderness, and peeling. It affects the outer layer of the skin and typically resolves within a few days with proper care.

Sun Poisoning: Sun poisoning is a more severe form of sunburn that extends beyond the surface of the skin. It involves systemic symptoms and may require medical attention to manage complications.

Ways to Prevent Sun Poisoning

  • Sunscreen: Regularly apply a broad-spectrum sunscreen with an SPF of 30 or higher. Reapply every two hours, especially after swimming or sweating.
  • Protective Clothing: Wear UV sun protective items like long-sleeved shirts, wide-brimmed hats, and sunglasses to shield your skin and eyes from direct sunlight.
  • Avoid Peak Sun Hours: Limit outdoor activities during peak sun hours, typically between 10 a.m. and 4 p.m., when UV radiation is strongest.
  • Stay Hydrated: Drink plenty of water to prevent dehydration, especially in hot weather. Adequate hydration supports your body's ability to cool itself.
  • Be Mindful of Medications: Consult with your healthcare provider about the sun sensitivity of any medications you are taking. Adjustments or precautions may be necessary.

Treatment Tips 

  • Cool Compresses: Apply cool compresses to the affected areas to soothe the skin and reduce inflammation. Avoid using ice directly on the skin.
  • Hydration: Drink plenty of water to combat dehydration and help the body recover from the effects of sun exposure.
  • Over-the-Counter Pain Relievers: Non-prescription pain relievers, such as ibuprofen or acetaminophen, can help alleviate pain and reduce inflammation.
  • Topical Steroids: In some cases, a healthcare professional may prescribe topical steroids to reduce inflammation and itching.
  • Medical Attention: Seek medical attention if symptoms are severe, including persistent fever, severe blistering, or signs of infection. Hospitalization may be necessary in extreme cases.

FAQs About Sun Poisoning

1. How long does sun poisoning last?

The duration of sun poisoning can vary based on the severity of the reaction and how promptly it is treated. Mild cases may resolve within a few days, while more severe cases could take a week or longer to heal. It's important to seek medical attention for severe symptoms to ensure proper treatment and prevent complications.

2. Who's most prone to sun poisoning?

While anyone can experience sun poisoning, individuals with fair or sensitive skin are more prone to developing this condition. People taking certain medications that increase sun sensitivity, such as antibiotics or NSAIDs, are also at higher risk. Furthermore, those exposed to specific plant toxins or chemicals that heighten photosensitivity may be more susceptible.

3. What does sun poisoning feel like?

Sun poisoning typically feels more intense than a regular sunburn. Symptoms include severe redness, swelling, and pain. The affected skin may be hot to the touch, and blisters may develop in severe cases. Systemic symptoms like headache, dizziness, fever, and nausea may also occur. It is a much more uncomfortable and serious condition than a normal sunburn.

4. Can sun poisoning be treated at home?

Mild cases of sun poisoning can be treated at home with measures such as cool compresses, over-the-counter pain relievers, staying hydrated, and keeping the affected area moisturized. However, if symptoms are severe or if there's an indication of infection, seeking medical attention is crucial. Professional medical advice ensures proper care and reduces the risk of complications.

5. Does drinking water help sun poisoning?

Yes, staying hydrated is important when dealing with sun poisoning. Sun exposure can lead to dehydration, and maintaining adequate fluid intake helps the body recover more effectively. Water supports the healing process and assists in minimizing symptoms like headaches and dizziness associated with sun poisoning.

6. Does sunscreen prevent sun poisoning?

Yes, sunscreen is a crucial preventive measure against sun poisoning. Regularly applying a broad-spectrum sunscreen with an SPF of 30 or higher helps protect the skin from harmful UV radiation. Sunscreen effectively reduces the risk of both sunburn and sun poisoning. Reapply sunscreen every two hours and after swimming or sweating for optimal effectiveness.

7. Can you take a shower with sun poisoning?

While it's generally safe to take a shower with sun poisoning, it's important to use lukewarm water and avoid hot showers, which can further irritate the skin. Gently pat the skin dry after showering, and avoid harsh soaps or scrubbing. If blisters are present, take extra care to prevent them from breaking, as this can increase the risk of infection.

8. Does Benadryl help sun poisoning?

Benadryl (diphenhydramine) may help alleviate itching associated with sun poisoning, as it is an antihistamine. However, it won't address the overall inflammation or pain. It's essential to follow the recommended dosage and consult with a healthcare professional if you have any concerns or if symptoms persist. Other over-the-counter or prescription medications may be recommended for more comprehensive relief, depending on the severity of the symptoms.

You can be a sun goddess and sun-savvy at the same time. Just be aware of the potential risks associated with prolonged sun exposure. Sun poisoning, with its array of symptoms and complications, underscores the importance of sun safety practices. If you suspect sun poisoning, prompt and appropriate treatment is key to a swift recovery.
