The Science Behind Ultraviolet (UV) Radiation and Its Effects

Science Behind

on Health

Ultraviolet (UV) radiation from the sun has long been known to be dangerous to human health. UV radiation is the invisible part of the sun’s spectrum that can reach the Earth’s surface. It is divided into three components, UVA, UVB, and UVC. UVC rays are the most dangerous, but fortunately, the ozone layer of the Earth’s atmosphere absorbs most of these rays. UVA and UVB are the most frequently encountered type of UV radiation.

UVA Versus UVB Radiation

UVA radiation has an effect on the deeper layers of the skin and is responsible for sunburn and skin aging. UVA radiation penetrates the skin more deeply than UVB radiation, but is only weakly absorbed. UVB radiation has higher energy levels and can cause skin cancer and cataracts. It mainly affects the top layers of the skin and is responsible for sunburn and tanning. However, both types of UV radiation can cause damage to the skin and overall health.

The Healty Effects of UV Radiation

Exposure to UV radiation can have serious health implications including skin cancer, eye damage, weakened immune systems, and premature aging. The most common health issue from UV radiation is skin cancer. In extreme cases, UV radiation can cause tissue damage and even melanoma.

Eye damage from UV radiation can result in cataracts, snow blindness, and pterygia. UV radiation does not just damage the eyes; it can also weaken the immune system by directly damaging cells or indirectly altering the skin’s protective barrier. This damage can make people more vulnerable to infectious diseases and even cancer.

How to Protect Yourself From UV Radiation

The best way to protect yourself from UV radiation is to limit exposure by avoiding being outside during peak hours. When outside, wear clothing that covers as much of the skin as possible, wear a hat, and use sunscreen with a sun protection factor (SPF) of 15 or higher. Sunglasses should also be worn outdoors to protect the eyes from UV radiation.
