メラトニンと前立腺ガン

以前読んだ『頭が良くなる照明術』に記述されていたこと。

『交代制で勤務する男性は、おもに昼間だけ働く男性に比べ、
3.5倍も前立腺ガンになりやすいことが、文部科学省大規模疫学研究班
の2005年の発表で明らかになっています。
眠りに関わるホルモンであるメラトニンは、前立腺ガン細胞の増殖を
押さえるとも言われています。体内時計が乱れると、このメラトニンの
分泌量が落ちるのが原因で、前立腺ガンのリスクが高まるのでは
ないかと見られているのではないか』 とのこと。
夜勤勤務は光を上手に使いながら健康維持しましょうと
いうことでした。
光によって体内時計をリセットして生活リズムが
壊れないようにするということ。
これを心がけていけば、リスクは弱められる。かも。
