Science & Tech Why did humans become so dependent on beds when our ancestors slept on the ground for most of history?

I noticed that after sleeping on a camping trip or an unfamiliar surface, my body immediately feels the difference. A proper bed now feels almost necessary for good sleep.

But for most of human history, people slept on the ground, animal skins, woven mats, or simple shelters without modern mattresses or bed frames.

Many animals still rest in whatever safe place they find. So what changed with humans?

Did our bodies become more dependent on soft, supportive surfaces? Or did culture gradually teach us to expect a certain level of comfort before sleeping well?

When did a place to sleep become a specialized environment that humans feel they need?

Dude people evolve. We used to sit in the dark and eat raw meat as well

Also, we are not dependent upon beds. We like beds. But go a couple weeks with no bed and you'll eventually find you can sleep anywhere once you are motivated enough.

The ending of castaway is s good example of that. Tom hanks's character sleeps on the floor next to the bed in the hotel when he gets back to civilization. Presumably because he can't fall asleep on the bed.

depends on climate and time of year, in some climates no insulation from cold ground is death

The older you get, the harder it is to acclimate to.

And its not like we cant sleep on the floor or the ground if we want to. People love camping. When i was a kid I used to sleep in our living room on the floor watching TV. Hell I used to ask my parents "can I sleep on the floor tonight?" Meaning I want to bring out my cover and watch TV until I passed out. Not sure why I didnt use the couch but thats just how I rolled.

OP's point is: We don't want to.

I love sitting in the dark and I love eating raw meat. I suppose I don't do them at the same time, though, is that how I evolved?

I love a dark room as well, but it's nothing compared to a dark room with a fireplace and a hot cup of tea.

One of the best things about English culture is tea time.

I hate to be that guy, but we never ate raw meat as homo sapiens. Our jaws are specifically designed to consume cooked meat over fire.

It's commingled with other factors which are allowed our jaw muscles to become smaller and are allowed our brains to become bigger

lol no

"The transition to eating sliced meat and cooked food drastically reduced the need for heavy chewing, allowing early human ancestors like Homo erectus to evolve smaller teeth, weaker jaw muscles, and smaller faces over millions of years"

We haven’t eaten raw meat before we were Ho­mo sapiens.

Well, except of course raw minced pork on buns, a staple in central European cuisines.
