Sunburn is a skin condition caused by overexposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. It results in redness, pain, and sometimes swelling of the skin. The severity of sunburn can vary, with mild cases causing discomfort and severe cases leading to blisters and peeling. To prevent sunburn, it is important to use sunscreen with a high SPF, wear protective clothing, and seek shade during peak sunlight hours. Repeated sunburns can increase the risk of skin damage and conditions such as skin cancer. Proper care and hydration can help soothe sunburned skin.
