possible? the auto-cooling pillow. Answered

I am the kind of person that flips over his pillow every fwe minutes so my face can be on the cool side for a bit. I was wondering if anyone has ever created a pillow that keeps one side cool the entire time. Can anyone help?

what about lining a pillow case on the inside with high gauge flexible tubing and sewing it to the case.

Then attach a low noise pump to one of the ends of the tubing and then attaching more tube to a plastic container filled with water then attach the other end of the tube from the pillow then attach the tube to the other side of the plastic container.

So I hear one "Chillow is good" and one "Chillow is a dud." Can we take a vote before I spend money on one?

I really think the products on the market today do not provide the relief some of us are looking for. I go to sleep every night with an Corn Filled small pillow placed on my neck that has been frozen overnight. I have two of them in the freezer and switch in the middle of the night to keep cool. I also keep a quiet fan by my headboard that blows constantly on my head (but this causes a really dry nose and throat) but most of all bothers my spouse in the winter. The corn pillows actually work pretty well (you can flip them and the corn on the other side are still cool a bit later) so I am seriously thinking of trying the buckwheat pillow that has been in the freezer to see how that works.. but I love the idea of the cool water or air flowing through the pillow but since I am a light sleeper I think the noise would wake me up. The issue for some people is that all those pillows out there are made for some people and for others whose heads become so incredibly hot at night it just seems like there is no relief except for a frozen pack of some sort so the corn filled or maybe buckwheat seems to work the best. I am thinking of getting a small fridge for my bedroom to just keep frozen corn packs that I can switch throughout the night so I dont have to go to the kitchen. SIGH... OH BTW, if you use any pack with a cloth cover in the freezer place them in a plastic bag so they do not absorb odors, I learned my lesson.

I suggest you look at the Oasis Body Pillow. It uses Thermoelectric (Peltier) cooling and stays cool, or warm if you want indefinately. Great for wonem with hot flashes or others with night sweats. It really works, no BS.

Hmm, I was thinking more along the lines of having a small quiet pump, slowly pump cool water through some small tubing running an inch or so under the place you head lay, which would absorb the heat, move on and then be pumped through a small radiator/fan combo to cool it again. It would never get you "terribly cold" but it would be cooler.

Inneresting...

What struck me was to find some sort of endothermic-reaction-based chemical cool-pak (opposite of those exothermic chemical heat-paks used for handwarmers and such) that you could tuck/build into your pillow. Preferably with the reaction inititated by pressure akin to the weight of human head.

Not sure if you could get enough heat absorbtion that you could just stick it in freezer during the day to renew, or if you'd have to somehow place a heatsink inside or underneath your pillow.

OTOH, a buckwheat pillow that's been in the freezer all day sounds like it'd be pretty darned good.

Change the pillow.
What you have isn't soaking heat away, it's keeping it close to your head.
Or try without.
Non-winter dense-filling perhaps?

I just use a soft cotton kitchen/tea towel (not terry cloth) draped over my pillow. I fold it in half lengthwise, lie on one end for a while, then when it warms up, I switch to the other end while the first end cools back down. In hot weather I use two so I can rotate among them more often. Plus I can bunch them up to kind of shim/customize my pillow shape.

If you're willing to part with a couple of dollars you could get a Chillow. As someone who's formerly owned one, I will tell you that they do in deed keep your head very cool all night.

That said, the original version (and possibly any versions that they've developed since) are not as durable as would be desirable. If you could make a tougher but equally reliable DIY version, you'd be all set.

Do you like to move around at night? If not, you could have some kind of setup using a pump and cool water, but have the pump and tub under the bed. Aren't there pumps that cool as they pump, like for computers? If so, you could use that for the above setup. I'm really interested in this.

I don't know how water pumps work, so I don't know ifthis would just blow up if it had to pump water vertically.

This Instructable may help, although it sounds a little expensive for just a pillow.

This one seems a little cheaper.

I really want to do this.

maybe, I think that a peltier unit and a heat sync would be more efficient because you could adjust the temperature, and be able to put it in your pillow so if you move around your fine, also having your head on the water cooling tubes may be like stepping on a water hose.

Actually frenchcrawler and cameronSS have raised a good point peltier units are silent and powered by anything as small as usb so they'd be good you could heatsink them into a box with fans that drew air through the pillow to underneath, it would be quiet ish and nice and cool, another trick is to create heat difference in your room and use the draft to cool wherever, I run hot all the time and hate sleeping in a bad bed, i always sleep with the duvet between my legs at the knee and only the bottom half of me covered, then i rest my head on the pillows alternating or just use an old magazine, the glossy means it feels kind of sticky from skin condensation but it feels really cool and never feels too warm.

what's better than the chillow is the cool touch comfort cushion. I've tried the chillow before, and it was just "eh". I wasn't too pleased with the fact that I had to put water in it...and leave it in there (i wonder what kind of bacteria grow in it..). But after some searching, i finally found one that does not require water, or really anything to begin using it. It's the cool touch comfort cushion- i got it straight from the manufacturer- www.cooltouch.net . It definately provides that cool pillow effect- and it'll last for hours. I use mine whe i'm sleeping on my back and in the morning, it's still a little cool..not bad for something I didn't have to do anything to. The only downside is that i wish they had a bigger size...maybe one for my entire body! :) But i think if you're looking for a cool cushion that'll last you all night- you cannot go wrong with this product! they also have different shapes and sizes. Again, i definately reccomend it!!! it's a lifesaver, especially in the summer!!! fyi~ the price on the website is about $40.

my guess would be that you could get a basic thermistor cuircuit that hooked up to a few ultra thin fans, when it measured a heat past say 30 degrees it would switch on. I would imagin you would need to insulate it for the noise but im sure you would end up with a very uncomfy pillow =/

My dad recently bought an EVSEAT to try out in our electric truck. It has a set of Peltier junctions with water circulating over them, and a network of thin hoses that circulate the water through the seat bottom and back. You can also switch it between a cooling seat and a heating seat. It works very well, and is currently on loan to an EV couple in Kansas City to test out in their Xebra PK. The only problem with it is that the body is not used to being cooled from below, so you get the sensation of sitting in a puddle for the first few minutes.

That was a long ramble, but just an idea. We are thinking of creating a mat like that to give the dog a cool place to sit in 105-degree summer heat. On the other hand, trickling water right under your head might tend to make you get up a lot at night.
