You breathe（呼吸） more slowly than when you are awake.

    During stages three and four, you sleep deeply. You don't hear sounds. Lights don't wake you up. Your heart beats more slowly than in stages one and two. The last stage of sleep is called Quick Eye Movement. During QEM sleep, you breathe faster, and your heart beats faster than in stage one through four. Your eyes move quickly under your eyelids.
