Re:Why Do We Sleep Under Blankets, Even on the Hottest Night... by toomanybeersies on Tuesday February 27, 2018 @08:38AM (#16473189)
It's all about what you're used to.

For a year or two I didn't sleep with a pillow, I can't remember why I stopped using one or why I started again. I was still sleeping on a mattress though. I just used my arm as a pillow.

When I'm hiking, I'm sleeping on the ground without a pillow, and I've never had a problem with it.

On the flip side, I always need an inflatable pillow or a pillow section built into my inflatable mattress when I'm camping, otherwise I need to sleep on my backpack or a pile of clothes or something. Can't sleep without a pillow for the life of me.
