What are UV rays, and why are they harmful?Updated 4 months ago
Ultraviolet (UV) rays are a type of electromagnetic radiation emitted by the sun. They are classified into three types: UVA, UVB, and UVC. While UVC rays are absorbed by the Earth’s atmosphere, UVA and UVB rays can penetrate your skin. UVA rays contribute to premature aging and DNA damage, while UVB rays are the primary cause of sunburn. Both types increase your risk of developing skin cancer, making sun protection essential year-round.
