Suppression of melatonin has been linked to cancer in some studies. The ability of fluorescent lamps to suppress melatonin in humans after nocturnal light exposure is strongly dependent on the color temperature of the lamp. While lamps with daylight color (6500 K) can significantly suppress melatonin, warm white lamps (2700 K or 3000 K) have a much inferior effect on melatonin suppression. Cool white colors (Color Temperature of 4000 K) have a moderate effect on melatonin suppression.〔(), DIN V 5031-100:2009-06 Optical radiation physics and illuminating engineering – Part 100: Non-visual effects of ocular light on human beings – Quantities, symbols and action spectra, DIN Deutsches Institut für Normung.〕 Therefore warm white lamps are recommended for use at nighttime in order to prevent melatonin suppression.〔(), DIN SPEC 67600:2013-04 Biologically effective illumination - Design guidelines, DIN Deutsches Institut für Normung.〕 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Fluorescent lamps and health」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
