What is Non-rapid eye movement (NREM)?

Non-rapid eye movement, or NREM, is like being deeply asleep and not moving your eyes around at all, just like when you're fast asleep and dreaming about cookie monsters.

What Does NREM Feel Like?

Imagine you’re tucked into your favorite blanket, and you're so cozy that you don’t even want to move. That’s NREM sleep. It's the part of your sleep where your body is resting and getting ready for the more active parts of dreaming.

During NREM, your brain is working hard too, it’s like a quiet cleanup crew fixing things up in your mind while you're asleep. Your heart rate slows down, and your body gets ready to recharge.

Why Is It Important?

NREM is one of the main stages of sleep, along with another part called rapid eye movement (REM). Without NREM, your brain wouldn’t get all the rest it needs, kind of like how a toy needs a break after playing all day.

So next time you're snuggled in bed, remember: you're probably in NREM sleep, and your brain is happily doing its job!
