What are the ways to protect from UV radiation?

Question

Hello doctor,

I am a 25-year-old male. I am exposed to the sun every day for a prolonged time due to my work schedule. As UV rays are produced from the sun, what are the potential health risks faced due to it? What are the different types of UV radiation? How do these types differ in terms of wavelengths and effects on human health? How does UV exposure contribute to skin aging, sunburn, and skin cancers? What are the effective strategies for protecting myself from UV radiation?

Please help.

Hello,

Welcome to icliniq.com.

UV (ultraviolet) radiation from the sun poses significant health risks. There are three types: UVA, UVB, and UVC. UVA has longer wavelengths, penetrates deeper into the skin, and contributes to skin aging and wrinkling. UVB has shorter wavelengths, affects the outer layers of the skin, and causes sunburn and skin cancers like melanoma. UVC is mostly absorbed by the ozone layer and does not reach the Earth's surface in significant amounts. UV exposure accelerates skin aging by damaging collagen and elastin fibers. It causes sunburn by damaging skin cells and DNA (deoxyribonucleic acid), leading to inflammation and pain. Prolonged exposure increases the risk of skin cancers, including basal cell carcinoma, squamous cell carcinoma, and melanoma. Effective strategies to protect against UV radiation include wearing protective clothing, broad-spectrum sunscreen with SPF 30 or higher, seeking shade during peak sun hours (10 AM to 4 PM), and wearing sunglasses that block UVA and UVB rays. Regular skin checks and prompt evaluation of suspicious moles or lesions are also crucial for early detection and treatment of skin cancers.

I hope this helps.

Thank you.
