A sunny afternoon in Knoxville is hard to beat. Whether you're hiking at Ijams Nature Center, cheering on the Vols, spending the day on Fort Loudoun Lake, or relaxing by the pool, it's easy to lose track of how much sun you're getting. While a mild sunburn is an inconvenience most people have experienced, sun poisoning is a much more serious form of sun damage that shouldn't be ignored. Knowing the difference between a typical sunburn and sun poisoning can help you get the care you need before symptoms become more severe. At AFC Knoxville, we're here to help you recognize the warning signs and get back to enjoying your summer safely.
What Is Sun Poisoning?
Despite its name, sun poisoning isn't actually a poisoning. It's a severe inflammatory reaction that occurs after excessive exposure to ultraviolet (UV) rays. While it often starts as an intense sunburn, sun poisoning can affect your entire body—not just your skin.
Anyone can develop sun poisoning, but your risk increases if you spend long periods outdoors without sunscreen or protective clothing, especially during peak afternoon hours.
Signs Your Sunburn May Be More Serious
A typical sunburn causes redness, tenderness, and mild discomfort. Sun poisoning, however, often comes with more severe symptoms, including:
- Large, painful blisters
- Severe redness or swelling
- Skin that's hot to the touch
- Fever or chills
- Headache
- Nausea or vomiting
- Dizziness or lightheadedness
- Fatigue or feeling weak
- Dehydration
- If you're experiencing symptoms beyond skin redness alone, it's time to take your condition seriously.
What to Do If You Think You Have Sun Poisoning
If you suspect sun poisoning, the first step is to get out of the sun immediately. Then:
- Move to a cool, shaded, or air-conditioned space.
- Drink plenty of water to help prevent dehydration.
- Apply cool compresses to soothe the skin.
- Take a cool shower or bath if needed.
- Avoid popping blisters, which can increase the risk of infection.
- Continue protecting your skin from additional sun exposure while it heals.
While these steps can provide relief, some cases require medical evaluation.
