Well, we certainly know from{#blank#}2{#/blank#}(evident) in the sleep center and that of many other scientists that naps can give you benefits for both your brain{#blank#}3{#/blank#} your body. But naps can actually be{#blank#}4{#/blank#} double-edged sword because while we're awake during the day, we're building up sleepiness or sleep pressure. So when you try to fall asleep at night, you'll fall asleep quickly and then you'll stay asleep. And when we sleep, we actually release that sleepiness so that we wake up the next morning feeling{#blank#}5{#/blank#}(refresh).

    The ideal nap depends on{#blank#}9{#/blank#} you want from that nap. Different stages of sleep actually give you different types of brain and body{#blank#}10{#/blank#} (benefit).
