其实对大多数人来说,NREM Sleep从婴儿到老年没有太显著的变化.反而是REM Sleep有较大的改变.
There is a sharp drop in the amount of REM sleep after
the early years of life, falling from eight hours at birth to less than one hour in old age. The change in the amount of NREM sleep is much less marked, falling from eight 8 hours to about five hours over our lifespan.
