Why do naps last 1 – 2 hours, but we can sleep for 8 hours straight at night?

I’ve just noticed, that when I take a nap, my body wakes myself up within 1 – 2 hours. This is probably true for everyone else too. But our bodies allow us to sleep for 8 hours at night. Why can’t our bodies nap for a full 8 hours without waking up? How does our body know this? How does our body differentiate between napping vs a nights sleep?

Hey OP, try napping in a fully dark environment. I mean ‘can’t see your hands in front of your face’ dark. You might find your nap goes for a little longer. Also, if your body really needs rest, and you’re not on medication and/or have any mental health issues, you should be able to sleep for however long you need.
