Chronic sun exposure damages trucker’s skin through glass - 2013.06.10

先日はエンビロンのフォローアップセミナーに参加してきました。
休憩時間に出てきたケーキとコーヒーに喜ぶかんばらさん。手前の資料は、パワープレートのものです。

何度か見たことのあるトラック運転手の写真,が今回も出てきたのですが、これは皆さまにも是非ごらん頂きたい!
ということで、かんばらさんは元ネタを見つけてきましたよ。

Trucker says sun did THIS to his face
以下、ざっくりと簡単な日本語訳。
69歳のこの男性、28年間トラックの運転手をしていました。
そしてその28年間、左側の窓から紫外線を浴び続けた結果がこの写真です。
紫外線は彼の表皮と真皮にダメージを及ぼし、皮膚日射病(dermatoheliosis)を引き起こしました。
皮膚日射病は、光老化(photoaging)とも言われ、UVAとUVBの慢性暴露により、皮膚は肥厚し、深いシワが刻まれます。
アメリカがん協会によると、UVは主に3種類あり、なかでもUVAはコラーゲンやエラスチンといった若々しい張りと弾力をたもつ皮膚の組織だけではなく、ある種の皮膚がんの原因にもなります。
また、UVBはサンバーンを引き起こし、皮膚がんの主な原因でもあります。
日焼けサロンであれ、野外であれ、累積したダメージは皮膚のDNAにまで及び、それらによる突然変異が皮膚がんを引き起こします。
しかしながら、UVAはガラスを通過しますが、UVBはガラスで遮ることができます。
車に乗る時は窓ガラスは閉めておくべきでしょう。
SPF30前後の、UVAとUVBの両方を防御する日焼け止めを塗布は最低限必要です。
また数時間ごとのまめな塗りなおしも徹底すること。
サングラスや帽子なども利用し、紫外線の強い日中(10時~4時)の時間帯の外出を控えることも心掛けましょう。

Chronic sun exposure damages trucker’s skin through glass
The striking photograph of a 69 year old truck driver in a recent New England Journal of Medicine article shows just how damaging the sun can be to your skin.
While driving a delivery truck for the last 28 years, the driver was exposed to ultraviolet A rays through the window glass on just the left side of his face. The rays penetrated the epidermis and the dermis, the first and second layers of the skin, causing a condition called unilateral dermatoheliosis.
Dermatoheliosis, also called photoaging, refers to changes in your skin due to chronic exposure to UVA and UVB rays. The result is a gradual thickening and deep wrinkling of the skin.
According to the American Cancer Society (ACS), there are three main types of ultraviolet radiation. UVA rays can cause cells to age and damage the skin’s DNA. They are linked to long term damage like wrinkles and can lead to some skin cancers.
UVB rays are the main cause of sunburns and are believed to cause most skin cancer. UVC rays are not present in sunlight and and not typically linked to skin cancer.
The Skin Cancer Foundation says UVA rays are less intense than UVB rays and up to 50 times more prevalent. They also penetrate the skin more deeply and are a major factor in skin aging and wrinkling.
The foundation’s website says, “UVA is the dominant tanning ray, and we now know that tanning, whether outdoors or in a salon, causes cumulative damage over time. A tan results from injury to the skin’s DNA; the skin darkens in an imperfect attempt to prevent further DNA damage. These imperfections, or mutations, can lead to skin cancer.”
But, the foundation says, “UVB rays do not significantly penetrate glass.”
Dr. Martin Weinstock, a professor of Dermatology at Brown University, and Chair of the American Cancer Society’s skin cancer advisory committee, says UVB rays don’t come through car windows unless they are open, and that even though you can get UVA rays through a closed window, the average person should not be overly concerned.
“In general there is not a huge amount of concern in people inside a car with the windows shut.”
Weinstock’s advice to consumers is to use a broad spectrum sun screen that protects against both UVA and UVB rays. “Using sunscreen SPF 30 or greater is the simplest bottom line. You gotta apply it whenever you’re out for maximum protection. You just have to apply it consistently and you have to reapply periodically, every few hours.”
The ACS also recommends protecting yourself from UV rays by covering up, wearing a hat and sunglasses to block the rays and by limiting direct sun exposure in the middle of the day. UV rays are usually strongest between 10 a.m. and 4 p.m.
