What is a potential risk of excessive sun exposure associated with tanning?

Excessive sun exposure poses multiple risks to skin health, with one of the most significant being the increased risk of skin cancer, particularly melanoma. This form of skin cancer arises due to damage to the DNA in skin cells from ultraviolet (UV) radiation. Initially, UV rays can cause sunburn, and over time, repeated damage can lead to mutations that drive the development of cancerous cells. Melanoma is particularly aggressive and can spread to other parts of the body if not caught early.

While reduced skin elasticity, faster aging of the skin, and allergic reactions to sunlight are also associated with excessive sun exposure, the immediate and serious nature of the risk of skin cancer—especially melanoma—makes it a crucial concern for individuals who frequently engage in tanning, whether through direct sunlight or tanning beds. Recognizing this risk is essential for promoting safe sun practices and protection against skin cancer.
