Sunburn is a form of skin damage caused by overexposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. When UV rays penetrate the skin, they cause direct damage to the DNA inside skin cells. The body responds to this injury by sending more blood to the affected area to help with the healing process. This increased blood flow is what causes the skin to turn red, feel hot to the touch, and become painful. Severe sunburns can also lead to swelling and fluid-filled blisters. While the damaged outer layer of skin eventually peels away, repeated sunburns cause long-term harm and significantly raise the risk of developing skin cancer later in life. To protect yourself, you should limit direct sun exposure during peak hours, wear protective clothing, and consistently apply a broad-spectrum sunscreen. 1, 2
Causes of Sunburn
- Natural Sunlight: Direct exposure to the sun’s ultraviolet (UV) rays, mainly UVB rays which damage the outer layer of the skin, and UVA rays which reach deeper into the skin.
- Artificial Tanning Devices: Using indoor tanning beds, sunbeds, and sunlamps that give off concentrated UV rays.
- Reflected Sunlight: Exposure to UV rays that bounce off bright or reflective surfaces like snow, water, and light-colored sand. Snow, for example, can reflect up to 80% of UV rays back onto the skin.
- Workplace UV Sources: Accidental exposure to artificial UV light from tools like welding equipment, bacteria-killing lamps, and broken or unshielded fluorescent light bulbs.
- High UV Environments: Spending time in places where UV rays are naturally stronger, such as high mountain altitudes, areas close to the equator, or outdoors during peak sunlight hours (typically between 10:00 AM and 4:00 PM).
- Lack of Sun Protection: Staying outside for long periods without using broad-spectrum sunscreen, wearing wide-brimmed hats, or covering up with protective clothing.
- Sun-Sensitizing Products: Taking certain medications or using specific skincare cosmetics that make the skin extra sensitive to sunlight, causing it to burn much faster than normal. 3, 4, 5, 6, 7
Symptoms of Sunburn
- Red, pink, or discolored skin
- Skin that feels noticeably warm or hot to the touch
- Pain, tenderness, or general discomfort in the affected areas
- Swelling around the sunburned skin
- Small, fluid-filled blisters that may break open and leak

- Signs of a severe, whole-body reaction (sometimes called sun poisoning), which can include:
- Fever and chills
- Nausea or vomiting
- Headache
- Dizziness, weakness, or extreme tiredness 8, 9, 10
Natural Remedies for Sunburn
1. Cool Water Compresses and Showers
How It May Help
Applying cool water directly to sunburned skin helps lower the surface temperature and quickly relieves pain and burning sensations. This cooling action causes blood vessels to narrow, which reduces inflammation and minimizes the swelling associated with ultraviolet radiation damage. 11
What Research Says
Clinical evidence confirms that immediate cooling therapies effectively decrease skin inflammation and slow down the progression of burn damage. Applying cool water limits the release of inflammatory chemicals in the skin, resulting in significantly faster pain relief and a reduced risk of deeper tissue injury. 12
How to Use It Safely
Soak a soft cloth in cool water and gently apply it to your sunburn for 10 to 15 minutes several times a day. Alternatively, take frequent cool showers. Pat your skin gently, leaving it slightly damp before applying a moisturizer to trap the water. 13
Potential Precautions or Side Effects
Never apply ice directly to your sunburn, as extreme cold causes additional tissue damage and delays healing. Avoid using harsh, drying soaps while taking cool showers. 14

Stop using calendula immediately if you notice itching, rash, or skin swelling, as these indicate an allergic reaction. 79 Avoid applying it to open wounds. 80
Foods to Avoid When You Suffer from Sunburn
1. Alcoholic Beverages
Alcohol acts as a diuretic, accelerating dehydration when your skin is already struggling to retain moisture. It also impairs the body’s natural inflammatory response and healing capacity. 81, 39
2. Highly Caffeinated Drinks
Excessive caffeine from coffee or energy drinks can further dehydrate the body. Since sunburn draws fluid to the skin, maintaining optimal systemic hydration is essential for recovery. 40, 38
3. High-Sodium Processed Foods
Salty snacks cause the body to lose water more rapidly. High sodium intake can strain your system when you need to maintain fluid balance to heal damaged tissues. 82, 83
4. Sugary Foods and Refined Carbohydrates
Diets high in refined sugar may promote systemic inflammation. Minimizing these foods can help the body prioritize its resources toward reducing skin redness and cellular repair. 84, 85
5. Spicy Foods
Spicy dishes can cause sweating and heat sensations that may irritate your already sensitive, inflamed skin. Keeping the body cool helps reduce discomfort during the initial recovery phase. 86, 33
When to See a Doctor When You Have Sunburn
1. Presence of Extensive Blistering
Seek medical attention if blisters cover a large portion of your body or if they become infected, indicated by pus, increased swelling, or red streaks. 11, 8
2. Severe Systemic Symptoms
Consult a healthcare provider if you experience high fever, intense chills, severe headache, confusion, or feelings of faintness, which may indicate systemic heat-related illness. 87, 88
3. Signs of Infection
If the skin shows increasing redness, warmth, or develops yellow crusts and drainage, see a doctor to evaluate for a secondary bacterial skin infection. 21, 9
4. No Improvement Over Time
Visit a professional if the sunburn pain does not begin to subside after a few days or if the skin shows no signs of improvement. 64, 89
5. Severe Eye Pain
If you experience intense pain, light sensitivity, or blurred vision following sun exposure, your eyes may have sustained damage requiring an urgent medical examination. 90, 91
