The Skin Cancer Foundation defines sunburn as "inflammation of the skin induced by ultraviolet (UV) radiation penetrating the skin's outermost layers."
Indoor tanning, like tanning beds, can cause sunburn. Long-term exposure to extreme UV radiation can even burn your eyes.
Mild sunburn symptoms often resolve within three to five days, though this time frame might vary from person to person.
Recovery from severe burns takes a few weeks. Usually, the rate at which a sunburn recovers is determined by genetics, existing health issues, and lifestyle choices.
Diabetes, smoking, poor nutrition, being overweight, and long-term stress are all things that can slow down the healing process.
Sunburn can't be fixed quickly, and sun damage can't be taken back. Still, there are many ways to treat a mild sunburn and keep from getting one in the first place.
Darker skinned people are less likely to become sunburned because their bodies produce more melanin, which blocks UV rays. Pale people burn more easily.
Sunburns increase the risk of skin cancer, including melanoma, which is caused by UV radiation or tanning beds.
