What is Sun Sickness (Sun Poisoning)?
Despite its common name, "sun poisoning" isn't caused by a toxin but is a severe, systemic reaction to excessive UV radiation. It indicates that your body has suffered significant damage beyond the surface level and is reacting with a range of symptoms. While a typical sunburn is marked by painful, red skin, sun sickness involves a much more intense inflammatory response, leading to a host of debilitating, flu-like symptoms that can affect your entire body.
The body's inflammatory response
When your skin is overexposed to UV light, it triggers a strong inflammatory reaction. This response is the body’s way of trying to heal the damaged cells, but it releases chemicals called cytokines that can cause systemic symptoms like fever and fatigue. This means that the illness is not just localized to your skin but is a widespread response involving your immune system.
The telltale symptoms of sun sickness
The signs of sun sickness typically appear within a few hours to a day after sun exposure and can last for several days or even weeks in severe cases. The symptoms can be categorized into skin-related and systemic issues.
Skin-related symptoms
- Severe redness and pain: The affected skin becomes intensely red, swollen, and extremely painful, often feeling hot to the touch.
- Blistering and peeling: Blisters indicate a second-degree burn, and they should be left intact to prevent infection. Peeling will follow as the body sheds the damaged layers of skin.
- Rashes: In some cases, a severe sun poisoning rash may develop, which can be intensely itchy.
Systemic symptoms
- Fever and chills: A fever accompanied by chills is a common indicator of a severe reaction, signaling the body's battle against the extensive UV damage.
- Headaches: Severe, throbbing headaches can occur, often worsened by dehydration.
- Nausea and vomiting: Feeling nauseous or experiencing vomiting can be signs of dehydration and the body’s overall distress.
- Dizziness and lightheadedness: These are often linked to dehydration and a loss of electrolytes.
- Fatigue and weakness: The body expends significant energy repairing the damaged skin, leading to overwhelming tiredness.
Sun Sickness vs. Heat Exhaustion
It's easy to confuse sun sickness with other heat-related illnesses, especially if the weather is hot. However, the cause and some key symptoms differ significantly. Understanding the distinction is vital for proper treatment and knowing when to seek emergency care.
Feature | Sun Sickness (Sun Poisoning) | Heat Exhaustion | Heat Stroke (Emergency) |
---|---|---|---|
Cause | Excessive UV radiation exposure | Overheating due to high temps, physical exertion | Dangerous core body temperature >104°F |
Skin Appearance | Severe, blistering sunburn; may be swollen | Clammy, sweaty, and pale skin | Hot, dry skin (or sometimes sweaty); flushed face |
Symptom Focus | Skin damage and systemic, flu-like illness | Dehydration, muscle cramps, fatigue, dizziness | Altered mental state, confusion, seizures, fainting |
Sweating | May be present, but the body's temperature regulation is less the central issue | Heavy sweating as the body tries to cool itself | Lack of sweating is a serious sign; body's cooling system fails |
Urgency | Seek medical help for severe blistering, high fever, or confusion | Find cool place, rehydrate, rest; can progress to heat stroke | Medical emergency; call 911 immediately |
How to treat sun sickness at home
If you are experiencing symptoms, taking action quickly is crucial. Here are some steps you can take for milder cases, but remember that severe cases require professional medical attention.
- Get out of the sun immediately: Move indoors or find a cool, shady area to prevent further damage.
- Cool your skin: Apply cool (not ice cold) compresses or take a cool bath or shower. Adding colloidal oatmeal to a bath can also soothe skin.
- Hydrate: Drink plenty of water and electrolyte-rich fluids. Dehydration often worsens systemic symptoms like headache and nausea.
- Soothe your skin: Apply aloe vera gel or a fragrance-free, soy-based moisturizer to damp skin. Avoid oily lotions that trap heat.
- Manage pain and inflammation: Over-the-counter pain relievers like ibuprofen can help reduce pain and swelling.
- Protect the blisters: Do not pop blisters. They protect the underlying skin and are susceptible to infection if broken.
When to seek medical attention
While home remedies can treat mild cases, you must know when to seek professional help. Go to the doctor or urgent care if you experience any of the following:
- Your skin is severely blistered or covers a large portion of your body.
- You have a high fever (over 101°F) and chills.
- You experience intense nausea and vomiting.
- You feel dizzy, confused, or faint.
- Your skin shows signs of infection (pus, increased swelling, red streaks).
Preventing future sun sickness
The best way to deal with sun sickness is to avoid it altogether. Prevention is key to protecting your skin and overall health. Here are essential tips:
- Use broad-spectrum sunscreen: Apply a broad-spectrum sunscreen with an SPF of 30 or higher. Reapply every two hours, or more often if swimming or sweating.
- Wear protective clothing: Opt for long-sleeved shirts, pants, and wide-brimmed hats made from tightly woven fabric. Consider sun-protective clothing with a UPF rating.
- Seek shade: Limit sun exposure, especially during peak hours between 10 a.m. and 4 p.m..
- Stay hydrated: Drink plenty of fluids throughout the day when spending time outdoors, not just when you feel thirsty.
- Be mindful of medications: Certain medications can increase your skin's sensitivity to the sun. Check with your doctor or pharmacist about any photosensitive side effects.

Conclusion
Understanding what getting sun sick feels like is the first step toward recovery and prevention. It is a serious condition that goes far beyond a simple sunburn, affecting your entire body with flu-like symptoms. By recognizing the warning signs and taking appropriate action, you can protect your health and enjoy the outdoors safely.
