In this stage, most of your body is temporarily paralyzed, but brain activity dramatically increases and your eyes rapidly move behind closed lids. The most intense dreaming happens during REM sleep, which empowers memory and complex thinking when you’re awake. In the earlier sleep cycles of the night, more time is spent in NREM sleep.

Without the proper balance of NREM and REM, you will not get the rest that you need, which can lead to widespread repercussions for your health and well-being.
