Impacts of UV Radiation on Human Health

Let’s explore the impacts of UV radiation on human health in more detail.

1. Sunburn and Skin Damage

UVB radiation is primarily responsible for causing sunburn. When our skin is exposed to excessive UVB rays, it can lead to painful redness, blistering, and peeling. Sunburn causes immediate discomfort and increases the risk of skin cancer in the long run. Moreover, repeated sunburns can accelerate skin aging, resulting in wrinkles, age spots, and a loss of skin elasticity.

2. Skin Cancer

Prolonged exposure to UV radiation is a major risk factor for developing skin cancer. Both UVA and UVB rays can damage the DNA in skin cells, causing mutations that can lead to the formation of cancerous cells. The most common types of skin cancer are basal cell carcinoma, squamous cell carcinoma, and melanoma. Melanoma, in particular, is a highly aggressive form of skin cancer that can spread to other parts of the body if not detected and treated early.

3. Eye Damage

The eyes are also susceptible to the harmful effects of UV radiation. Prolonged exposure to UVA and UVB rays can cause various eye conditions, including cataracts, photokeratitis (a painful eye inflammation similar to sunburn), and macular degeneration. These conditions can lead to vision loss and, in severe cases, blindness.
