4. Sleep in a dark room.
Too much light in your room, either blue light from electronics or light peering through the curtains from outside, will interfere with your sleep and the secretion of melatonin. If you can't eliminate certain electronics from your room, nor change to darker curtains or fully-shutting blinds, then invest in a good sleep mask. Don’t forget to take your sleep mask along for long flights as well.
4.睡眠時光線宜暗
無論是電器發的藍光還是從窗簾透進的光線。房間若是太亮,就會影響你的睡眠,干擾褪黑激素的分泌。如果你無法減少房間里的電器,也不能換副較深的窗簾或不透光百葉窗。那就置購一副深度睡眠眼罩吧。在搭長途航班也不要忘了捎上它。
