My understanding is, your stomach is slightly to one side (a bit like your heart is; you’re only symmetrical on the outside) and so laying on one side, your stomach is above your centerline, if you lay on the other your stomach is below your centerline. Sleeping with your stomach on the “high side” means its easier for stomach acid to leak up into your esophagus, which burns!
Oh, I naturally have to sleep on my side, as front and back are both uncomfortable (for back my ass is a bit too big to not make my lower back feel odd). I sometimes have issues with digestion/acid reflux, so maybe I instinctively sleep left side? I noticed I kept going left instead of right.
I’m convinced it’s all BS. The best thing for the human body, in nearly every field, is variety. Sleep however you want, mix it up, whatever. Your comfort is the best indicator. And the consequences of a bad sleeping position are rarely so dire.
You know what’s fun? The post-surgery “you always sleep on this side? Learn to sleep on the other one because you’re going to be this way for weeks, motherfucker” sleeping position.
I had jaw surgery a few years back, and I had to adjust to sleeping sitting up (believe me, the surgery made me tired enough to be able to do that) for several weeks because I couldn’t risk messing up my jaw while it healed.
If I sleep on my stomach I can’t move my neck the next day, right side my right hand goes painfully numb, left side my left hand goes painfully numb, back both hands go numb. There is literally no position I can sleep in that I don’t wake up after a couple of hours and have to shift to a different position.
Dude, my arms kept falling asleep at night. I randomly mentioned this to my physical therapist (I was there after a knee surgery) and he put me on a massage bed and pulled my head. Not like some quack chiropractor, but just slowly pulling my head, stretching my neck. Fuckin problem went away and never returned. Closest thing to real magic I have experienced.
I didn’t, but I feel this will create more problems than it will solve
Hands are either able to freely move, but inside a narrow space, which will traumatize them and extend muscles, or they are squeezed between the chamber walls and those kind-of-filler-pillows, restraining motion.
Also, those who market it as a phone-comfortable bed clearly forget that phones and large narrow holes are a terrible combo. Oh, and for God’s sake, forget about ever eating ANYTHING on there.
First, breathing. For starters, you shouldn’t drown, for which you either have to be strongly fixed in a position with face up out of the liquid (which will be super uncomfy), or you should depend on oxygen mask (which is very dangerous when you’re unconscious during sleep)
Second, skin breathes too - and in liquids, the pores close and skin can’t breathe - which will eventually lead to hypoxia even if you breathe normally.
Third, skin gets irritated and damaged at prolonged contact (like, you know, 8 hours of sleep a day) with just about any liquid. It should be insanely inert.
Fourth - the thermal conductivity of such liquid should ideally be the same as air - too much (which is just about any liquid) would be harmful for your body’s thermal regulation and, again, for skin, too little would make you overheat.
Fifth - you need a liquid in which you can be suspended, which is impossible to precisely measure since our buoyancy constantly changes due to us breathing, and our breathing patterns change as we move between phases of sleep.
TL;DR - There’s a reason all those vats are part of sci-fi: as cool as they look, they are insanely impractical.
