Exploring the Dangers of UV Rays
UV rays, also known as ultraviolet rays, are a form of light that is derived from sunlight. These rays can be categorized into three types: UVA, UVB, and UVC.
UV rays are predominantly reflected by the ozone layer, with UVC rays being almost completely blocked. As a result, approximately 99% of ultraviolet rays that reach the earth’s surface are categorized as UVA rays, with a smaller portion consisting of UVB rays.
Excessive exposure to UV rays can lead to various detrimental effects on the skin, including sunburn, heatstroke, premature aging, and an elevated susceptibility to skin cancer.
