Of all the risks driving a truck brings this has to be the least expected. But this facial ageing was the result for one man.
We all know the value of limiting our time in the sun and more importantly, wearing the sunscreen. It's no secret that lots of sun damages the skin.
Too much ultraviolet radiation from the sun has been tied to premature aging, more wrinkles and a raised risk for potentially deadly skin cancer.
An image published in a recent issue of the New England Journal of Medicine could be a powerful message to support the warnings. It paints a clear picture of what kind of damage the sun can cause a person's skin.
This unidentified 69-year-old trucker (pictured above) who has been on the road for 28 years has accumulated lots of exposure to ultraviolet A (UVA) radiation.
The man's condition is called unilateral dermatoheliosis and the man's skin has been gradually thickening over the past 25 years.
UVA rays transmit through clouds and window glass to penetrate the skin's layers, and have been tied to aging and wrinkles. According to the journal, chronic UVA exposure can result in thickening of the skin's top layers, the epidermis and stratum corneum, as well as destruction of the skin's elastic fibers. The truck driver took the brunt of the damage on the left side of his face because of his many hours behind the wheel.
Experts had thought only ultraviolet B radiation (UVB), which cause sunburn, were the main cause of skin cancer but recent research suggests UVA rays can damage DNA in the skin's deepest layers, increasing risk they become cancerous.
Doctors eventually recommended to this man sun protection, vitamin A creams called topical retinoids and frequent screenings for skin cancer.
