问题 A a long afternoon nap
B the peak production of melatonin
C poor health
D low sleep efficiency
E good sleep efficiency
F exposure to blue light
A lower production of the hormone melatonin is due to______.
选项
答案F
解析 句意：褪黑素分泌不足是因为暴露在蓝光下。根据第三段的“Short wavelength bluelight…stops production of the sleep—inducing hormone melatonin and makes you feel more active”可知，来自太阳、电脑、平板电脑或手机屏幕的短波长蓝光会抑制促进睡眠的褪黑色素的产生，让人毫无睡意。故选F。
