UV radiation is classified into three types: UVA, UVB, and UVC. UVA rays penetrate deep into the skin and contribute to aging and long-term skin damage. UVB rays cause sunburn and are the primary cause of skin cancer. UVC rays are absorbed by the Earth's atmosphere and do not reach the ground. Nurses should inform patients about the dangers of UVA and UVB rays and the importance of protective measures.
