Final answer:
Sunburn is a burn to the skin caused by overexposure to UV radiation. It can lead to skin damage and increase the risk of developing skin cancer. Applying sunscreen and taking protective measures can help prevent sunburn.
Step-by-step explanation:
Sunburn is a burn to the skin that is caused by overexposure to UV radiation from the sun's rays. When the outer layer of the skin is damaged by UV light, it results in sunburn. People who experience one or more serious sunburns are significantly more likely to develop skin cancer.
The skin has natural pigment molecules called melanin that act as a natural sunblock and protect the body from UV radiation. Light-skinned people are more prone to getting sunburned quickly because they have less melanin in their skin.
To avoid sunburn, it is important to apply sunscreen with a high sun protection factor (SPF), wear a hat and protective clothing, and limit exposure to the sun, especially during peak hours when the UV radiation is strongest.
