I've used more beds than I can count. Box spring, Japanese futon, air mattress hard floor, purple. The absolute best is a waterbed. It disperses weight the best and leaves you in comfort. They are heated which further relaxed your muscles and conserves energy. You wake up as you went to sleep, spread out and relaxed. If you don't have much body fat, it's easy to wake up curled up in a conventional mattress and more blankets are no solution as you'll overheat. They faded in popularity as landlords began banning them and home construction went downhill in quality. There's a study showing improvements in insomnia and falling asleep quicker. I'm somewhat surprised there's not more research on them and bed types in general.

The reason redditors dislike them is that they are bad for multiple sleepers and sex. It you're on your own, it's objectively the best. It's also very anxiolytic, feels like you're enveloped in comfort.

>>15189685

How are they heated? Do you replace the water or is electric?

>>15189714
There is 350W electric heating element that is placed underneath the water mattress that regulates the temperature up to about 100 degrees F. Very little fluctuation once at the desired temperature, never varies more than a degree relative to what it is set at.

>>15189685
They wreck my back. The best I've found is the Sleep Number bed, but only the iLE. I tried a cheaper version, but it sucked. No back pain whatsoever after getting one.

>>15189736
What's your weight? Did you use a waveless (baffled) or free float waterbed? Was it heated properly?

i will not eat the bugs and i will not sleep on the floor.
i recommend hybrid memory foam spring. full memory foam gets too hot and full spring gets depressed over time to a point where u can feel the springs in your back

>>15189685

Aside from waterbeds, how would you rank your experience with other systems?

>>15189769

I mean as you see in those videos, many cultures have beds with hard flat surface, you dont need to sleep on the floor.

>>15189769

Sleeping above ground has always felt wrong to me
Ideally we spend our idle time as low to the ground as possible

>>15190171

Do you sleep on the floor?

Bump

>>15189768
They were all fairly comparable, at least mattresses. But to rank decent box spring = purple original > memory foam > Japanese futon > air mattress in summer > floor > air mattress in winter. Memory foam with tempurpedic memory foam pillow was the worst for skin even with frequent cover changes. The waterbed is the only thing that has made an appreciable difference in sleep quality (faster onset, longer duration, more refreshed). My health in general has improved since getting one brand new a year ago.

>>15188384
I recently switched to one of the hardest mattresses they make and my back has felt way better.

>>15188384
I can sleep standing up.

>>15190999

That sounds great man. Do you recommend one specific waterbed or feature?

>>15191042

Are you a back sleeper or side sleeper? Is ist a spring matress?

>>15191054

Are you military? How do you feel after sleeping standing?

>>15191093
Hardside frame with a waveless mattress (meaning several internal layers) and definitely a heater strip underneath . Waveless water mattresses are more expensive. But I don't have a reference to compare it against, no idea how if any different the full motion ones are in feel.

>>15189685
They ruin your back and what you said about heat sounds bad. You sleep deeper and live longer if you sleep in a cold (within reason) room. A little like the fruits, vegs and meat in a fridge.
I love sleeping in temperatures 7-14c.

Pillows, what should I get?
Are mypillows good?

I dont give a fuck about political anything I just want to not have fucking neck pain.

>>15191188
Back has never felt better since getting one. You can turn the temperature down or off and because water has high thermal conductivity, it begins to make you feel cold if it is "only" 80 degrees F. If a waterbed was cooled down to 14C, it would might even cause hypothermia after a night. Hospitals sometimes use waterbed like devices with chillers to bring body temperatures down.

>>15191210

This guy says that pillow is not necessary, but if you use one, try to find one that encourages your body to sidesleep

https://m.youtube.com/watch?v=O8UoAASCUsQ

>>15191210
try sleeping with no pillow. or get a thin one like the OG purple pillow. reminder america is a nation of fat 18" neck retards so the pillow can't be flat for them, they need these giant things filled to the brim where their bowling ball head makes it sink in like it's nothing.

>>15191264

Yeah, pillows should be ergonomical, always hated the oval shaped down-stuffed pillows

>>15191328
hate them too

>>15188384
you sleep good if you do enough physical activity during the day to be physically exhausted at the end of the day. if you sit in front of the computer all day then you probably are taking drugs to sleep or sleeping poorly no matter how perfect your bed is.
scapegoating inanimate objects with the blame for the consequences of your own laziness is a lame coping mechanism. sleep happens due to being tired, if you're too lazy to do anything that takes effort all day then you won't be tired at the end of the day.

>>15191598
This is projection by someone who never worked 16 hour days. You're worn out and will fall asleep in bad positions that mess up the neck. That's why a bed is everything in that situation and why the literal only free time you have is sleep and why you want to maximize it to feel as good as possible for the next day.

tbf every time i did try sleeping on the floor just because i felt like it, it really did feel nice

>>15191873
doing it for weeks the knees and hips begin to hurt.

>>15188384
There's a surprising lack of research on how different beds affect sleep. No surprise given most sleep doctors are pseudoscientists aren't interested in exploring actual questions.

>>15192095

This is because anthropologists are retarded, and because meds are greed reptiles who dont think about their patients outside of the hospital

>>15191099
I am not in any military. I wanted to go in the Space Force so I can use the Space Computer to make research, but they didn't let me join.

I learned standing sleep in college. I got to go in a program and they made me do it but I don't remember what the goal was.

>>15193007

Ok, so you wanted to join space force to use the space computer. Why?

Second, program of what?

>>15192335
It's sleep medicine in particular. Other fields they like to experiment even if they don't care about the patient. Sleep medicine they don't even care about the science.

>>15193165

Do you think it will eventually change?

When I was a kid I used to actually sleep on the floor very often even though I had a bed. Guess I was ahead of the game.

>>15193283
Not without a total rejection of diagnostic benchmarks which were predicated on AASM tests with sample sizes of ONE patient and not without realizing the diagnostic uselessness of electroencephalography and not without proper years long education in psychopharmacology. They are lung doctor hacks with an easy job. Like most in medicine, they prioritize treatment of old, fat and severely diseased patients and leave healthy looking ones hanging.

>>15193143
I didn't have a plan for the Space Computer back then. I would just see what are the powers of the Space Computer and then make a research topic based on what I think the Space Computer can do.

I have a rough plan now but probably the military won't let me use their Space Computer. If it is a normal computer with a big amount of RAM, then I make it count big numbers. If it is a quantum computer, I do experiments to see can I make an encryption that makes a quantum computer useless, or at least a lot less useful? I have an idea of how to do this, but no hardware to test the idea with. After that make it count big numbers.

I would also need assistants and the assistants are maids with huge boobs who help with tasks like get lunch and clean the lab and argue with me about Numbers and Computers and get research papers that can be helpful translated into English so I can read it better and print things out. I keep having problems from interesting math that got made in places like Poland not being translated into English.

If there has to be a uniform then it can be the Space Force Space Maid Dress uniform and it looks like a maid dress and now Space Maids can help with Maid Space.

>>15194037

Stay away from me

>>15191252
First of all, yes, the video correctly highlights that side sleep is the most natural and probably healthiest. But:
>removal of Alzheimer's protein
This tells you everything you need to know about "I fucking love science!" videos like this.
They easily get outdated -- but it's not like they would (or sometimes can) get pulled (I am speaking generally, not saying this video should be pulled).

The cited claim "sleep debt can't be made up" is also more than suspect -- it's clownish. The body does it for a reason, and millennia of human experience of feeling more rested after a weekend of catching up can't be meaningfully argued with. I guess the popscoi point about sleep debt being un-recouplable is about something amorphous like long-term general wellness. and it being sacrificed.

>>15194985

Would you say that the information on sleep and alzheimer is outdated?

>>15195328
https://www.drugdiscoverynews.com/what-now-for-the-amyloid-hypothesis-15611
>In July 2022, a bombshell dropped on the Alzheimer's disease research field. For years, researchers had searched for something that caused the disease’s telltale amyloid plaques — complex tangles of a protein called amyloid-beta (Aβ) frequently found in the brains of patients with neurodegenerative disorders. A series of studies published starting in the mid-2000s reported the discovery of a toxic form of Aβ in the brains of mouse models of Alzheimer's disease called Aβ*56. Researchers hoped that Aβ*56 was the protein that snowballed into those amyloid plaques. But a team of sleuths found that many of the papers describing Aβ*56 were fraudulent and contained an array of faked images and blots. The fraud seemed to call the entire idea of amyloids causing Alzheimer’s disease into question.

>>15195356

MAN ARE YOU FUCKING KIDDING. ARE FUCKING FORMAL SCIENCE THE ONLY THING THAT HUMANS CAN DO. IS IT CAPITALISM?

IS THIS LIKE ALREADY SPREAD OR WHAT IS GOING TO HAPPEN?

>>15195356
Based high IQ post.

>>15194843
This was pretty much the recruiter's attitude too. I don't really understand why. The military wastes tax money on pointless or stupid or counterproductive things all the time (See Israel, Ukraine, Afghanistan and Iraq).

Letting me use the Space Computer and giving me assistants who are maids wouldn't even register in the top 10000 wastes of money if I totally failed to produce anything of value, and if I succeed, all my research and experiments are reproducible and now nobody has to worry about Chinese quantum computers decrypting important things.

>>15188384
I slept on the floor for almost 10 years now and can't complain. But I wouldn't be able to sleep without comfy blankets above me.

>>15197021

How did you do in winter?

Did you use some kind of insulation?

>>15197109
Well most of the time I use an old blanket for padding but more importantly I live on the gound floor in a building with district heating so the floor never gets cold. At least for me.
In my old place I had more problems during summer (south facing, no ac) and moved to the kitchen floor to let my leg or arm lie on the cold tiles to cool down.

>>15197109
Sleep outside in winter.

Bump, not much scientific literature on bed types. Offer anecdotes, hypotheses, and mechanisms please sirs.

>>15191188
>You sleep deeper and live longer if you sleep in a cold (within reason) room.
You can always make the room colder. I like a heavy blanket and a cold room.

Why dont you tell your sleeping experience?

I always sleep naked on a cold stone floor. No pillows, no sheets, just how God intended it.

>>15202640

Expand.

Do you live in warm climate?

Do you use any insulation?

How is your sleep quality?

This professor Jerome Siegel from UCLA, did a study on the sleeping behaviours of 3 modern hunter gatherer societies, and one thing pointed out is that the 3 slept on hard surfaces, being the floor, or beds made of treebark.

stomach sleeper master race
my mattress with a pillowtop has the middle sunken in like a hole and it sucks

>>15203582
How do you breath?

>>15203582

Do you feel good when sleeping like that? Isnt that like the worst position?

I've slept on a thin blanket on the floor for many years now. I sleep on my side and use my arm as a pillow. I tried sleeping on my bed recently and my back hurt terribly the next day after waking up. Never again.

I slept nude on the concrete floor of the Kitchner segregation unit of the Calgary Young Offenders centre with a canvas babydoll that I could use as a bit of a blanket in the summer, or as a mattress in winter.
The 2 inch wide "window" was not well insulated and when the temperature dropped below -20ish I could always see my breath.
I bet these conditions were fairly similar to how ancient humans would sleep in caves before they had fire.
I did not notice any appreciable health benefits.

>>15204868
Through my nose.
>>15205002
Yes. No back problems at all whatsoever and I've been sleeping this way for as long as I can remember.

>>15205266

What are the resons you slept like that? Are you from a warm climate?

>>15205532

Did you get sick? How do hou prefer to sleep?

Is this expensive giant butt-pillow still an ideal thing?

>>15205677

Since when is the ideal thing?

>>15188384
Only anecdote. I started sleeping on waterbeds and never had back problems anymore.

I'm having back pain in these past weeks. Very rarely, or I would dare to say, never I had it this badly (it not that bad, actually) before. Used to take naps on the floor before real sleep. I felt good afterwards, usually. But not anymore. I assume that office work also plays a big part on it

>>15207024
Yes because Asians know how to have healthy habits

>>15207100
sure schizo

>>15207024

It seems that hardbeds and hard surface, are better in general for sleep quality.

I wonder when did we start to normalize sleeping on springbox or foam

>>15207159
no

>>15207200

Prove it

>>15195375
at least it keeps evolving

>>15203582
based fellow stomach sleeper, they won't know what they're missing out on until they try it for themselves.

>>15191188
Are you sure about the lower range there anon.
I sleep in my van year round in northern europe and when its below zero sleep is like a wonderful coma. wake up fully rested with ice in my beard every morning.

>>15207491

>I wonder when did we start to normalize sleeping on springbox or foam
Based on my limited knowledge of history I can guarantee you that, like most of our customs, they stem from the Roman Empire era.

>>15188384
Friendly reminder to protect your penis from insects

>>15207860
If I'm sleeping without a pillow I never use my arm as one for my neck. Just sleep without doing it.

memory foam gave me back problems as a side sleeper.

switching to a FIRM mattress solved them all in like a month

>>15193461
Their approach and your approach both seem overcomplicated for the lion's share of normal healthy people concerns.

Bad sleep impacts objective behaviors. This can be measured.

Why would you need any deep psychopharm knowledge?

We don't need an expert in thermodynamics to evaluate where a 67F room is better for alertness in the morning than a 78F room.

>>15208332
