While sun exposure has benefits, excessive exposure poses significant health risks. The most well-known risk is skin cancer, including melanoma and non-melanoma skin cancers such as basal cell carcinoma and squamous cell carcinoma. Additionally, chronic sun exposure can lead to photoaging, characterized by wrinkles, loss of skin elasticity, and pigmentation changes. There's also an increased risk of ocular diseases like cataracts and macular degeneration.
