Eli5: Why do adults sleep with pillows when babies do not? What are the benefits of using a pillow as an adult?

483 views

I noticed that I actually slept better this week when I wasn’t using a pillow. Made me curious.

ETA: I think my framing was slightly unhelpful. I do understand why babies don’t sleep with pillows due to the risks. I am more curious about if there are benefits to using a pillow as an adult.

OP, maybe you’d benefit from a less dense pillow, i.e. one that allows your head to sink closer to the mattress, but still provides some comfort. I sleep on my belly and this was a game changer for me.

babies are too dumb to know how to use a pillow. plus like u/freecain said, their heads are too big.

One of the benefits of using a pillow as an adult is that sometimes you sleep on it incorrectly and create neck pain. This helps detract from pain in other areas of the body, such as your knees, back, or soul

Had to scroll pretty far to find it buried, but the fact is, babies should not sleep with any soft bedding. No stuffed toys, no pillows, firm mattress, light blankets/swaddles. If they roll over onto a pillow, they can suffocate.

I imagine most of us use a pillow because we were trained to. It’s perfectly fine to sleep on your back without one and there are likely billions of people who don’t use big fluffy pillows every night. I use a pillow for side sleeping, but find it is worse for back sleeping and I wake with a stiff neck.

Babies heads are really big in proportion to their body. In toddler hood (12-36 months) their head is roughly a 3rd of their weight.

Neck support when sleeping on your side. Arguably you don’t need a pillow if you exclusively sleep on your back.

I used to hate pillows. They were just there to put over my head if it started getting light out because I have insomnia. Like a year ago I bought a pillow that’s like torn up pieces of memory foam and it has a zipper so you can add/remove the foam. I took like 3/4 of the foam out snd I love it. I usually use it as is which is soft but very thin but if I feel like my neck needs more support that knight I fold it over and then it’s nice and fluffy. I sleep a lot better too which I’d a miracle for me.

Is there a helmet pillow that blocks out noise and comfortable for any sleeping position?
