Spending time outdoors is a great way to enjoy fresh air and sunshine, yet too much sun leads to a painful dilemma, sunburn. Whether you are spending the day at the beach or simply running errands, prolonged time in the sun with exposure to ultraviolet (UV) rays can damage your skin. Our dermatologist in Houston wants you to be informed and keep your skin safe from the sun.
What Causes Sunburn?
Sunburn results from exposure of your skin to excessive UV radiation from the sun or from artificial sources like sunlamps or tanning beds. The UV radiation penetrates the skin and injures the skin cells, leading to an inflammatory reaction. While the severity of sunburn is correlated with skin type, UV intensity, and exposure duration, even short exposure to the sun without protection will result in damage.
Certain factors increase your risk of sunburn, including:
- Fair skin: People with fair skin have less melanin, the natural product that defends the skin against UV rays.
- Time of day: UV radiation is strongest between 10 a.m. and 4 p.m.
- Altitude and latitude: At higher elevations and closer to the equator, you are exposed to more intense UV radiation.
- Reflection: Surfaces such as water, sand, and snow reflect UV radiation, boosting exposure.
- Insufficient sunscreen: Not applying broad-spectrum sunscreen leaves your skin vulnerable to sun damage.
Understanding Sunburn Symptoms
Sunburn symptoms range from redness that is mild to pain and blisters. Symptoms may take a few hours to appear and can take 24 hours to reveal the full extent of the burn. Common symptoms of sunburn include:
- Redness and heat: The skin is red and warm or hot to the touch.
- Pain and tenderness: The affected skin is generally tender and may be sore or painful.
- Swelling: Mild inflammation can cause the skin to swell slightly.
- Itching and peeling: Skin may peel and become dry as it begins to heal.
- Blistering: Severe sunburn can lead to blisters containing fluid that may burst and become infected if not properly cared for.
