Another interesting thing I read from this book

are:

“晚上睡觉时,不可开小夜灯,最亮的光度,决不可超过星星和月亮,因为原始人就是这样。”

Let me translate: “When sleeping at night, don’t use night light. The brightness of the room should not be more than the star light and moon light, should be just the same as how primitive people lived”.

Reason being: the eyes can only fully rest in full darkness.

In the book, it mentioned also, some scientific research shows children below two who use night light to sleep is prone to be short-sighted近视.

…how true ?? I don’t know…..
