What Are UV Rays?

Ultraviolet (UV) rays are a form of electromagnetic radiation that comes primarily from the sun. Although invisible to the naked eye, UV rays have more energy than visible light and can penetrate skin and eyes, causing damage at the cellular level. Artificial sources like tanning beds also emit UV radiation.

Why UV Rays Are Dangerous

Overexposure to UV radiation can lead to numerous health risks. These include sunburns, premature skin aging such as wrinkles and age spots, eye damage including cataracts, and a significantly increased risk of developing skin cancers like melanoma.

Types of UV Rays

There are three types of UV rays: UVA, UVB, and UVC. UVA rays penetrate the skin more deeply and are primarily responsible for premature aging. UVB rays are more intense and are the main cause of sunburn. UVC rays are the most dangerous but are completely absorbed by the Earth's atmosphere and do not reach the surface.

Which UV Rays Are Worse?

Both UVA and UVB rays are harmful. UVB rays are more likely to cause immediate skin damage like burns, while UVA rays cause long-term damage, such as skin aging and deeper DNA damage. Effective sun protection should shield against both types.

How to Prevent UV Damage

To protect yourself from UV damage, apply broad-spectrum sunscreen with an SPF of at least 30. Wear wide-brim hats and UV-rated clothing that covers your arms and legs. Choose sunglasses that block 100% of UVA and UVB rays. Cosmetics with built-in sun protection can also add a layer of defense, but should not replace sunscreen. Seek shade during peak UV hours (10 a.m. to 4 p.m.) whenever possible.
