Interesting. Living in Japan there is still a strong culture to try to avoid using air conditioning at night (in particular among the elderly), so there is a whole market for both staying warm in bed during winter and cool in bed during the hot and humid summers. My own family has primarily been using mattress protectors that conduct heat more efficiently [1], towel blankets (タオルケット) [2], and gel pads than are stored…

Why?

Good! I'm glad for any alternatives to 8sleep. I have two of their beds, and love them, but bought them before they starting requiring a yearly subscription, which I HATE. Unfortunately, they are the best product available as far as I can tell. Though definitely expensive.

Superstition

There’s a little subtlety to it. In some (all?) parts of Asia it’s intentional misinformation to reduce power usage.

This is the new venture capital model. Everything must be (or come with) a subscription. It's a way to take an area that has low technological innovation (little reason to buy next year's cooling mattress, which is the same as last year's mattress) and turn it into recurring income. As a bonus, all the smart features that you bundle into the subscription are also the personal data of people with high disposable incom…

Not just venture capital. Established businesses too

Investors like recurring revenue because it's simple to understand. You can just slap a multiple on it to figure out the valuation of a business

Wow. I do cold showers too, but never before bed. It'd wake me up!

The method works, and I am going to elaborate on it a little. As the poster said, start warm, work your way down to cool, then cold. Very cold. But what really seems to kick one off to dreamland is not drying your hair, instead putting a towel down on your pillow. As your hair dries, you'll get some more evaporative cooling strictly for your head, and that helps even more

Have you tried a hot shower instead just before the bed. The trick is that it cools down the core when you leave bathroom (by bringing blood to the surface).

Extremities should be warm, the core(CBT)—cold, to fall asleep easier.

> Compressor I would think these would be too loud for a comfortable sleep environment.

You could put a small compressor outside and connect a well-insulated hose to pump the refrigerant inside, just like a split system air conditioner. Then the noise in your bedroom will be no worse than the occasional hum of a fridge in the other room. As someone who lives in a humid climate, I wouldn't even think of using an evaporative cooler anywhere in my home, for any purpose, period. It's either compressors or n…

Does the water need to be that cold? I would think the cooling can be accomplished just by having a large enough water tank and possibly a radiator and fan so that the thermal mass would prevent your body from heating it up for the 8 hours or so you spend on bed.

I was just about to buy almost this exact setup! Excellent to see it's effective. I thought I was mad looking into fish tank coolers. I was thinking though skipping the evaporative cooler and going with a compressor model. Quite a bit more expensive but I think it'll be more effective in the humid North East. I have realized over the years that I need to be seriously cold to sleep well. My health watch always registe…

Would you mind sharing which watch (model) offers this? I guess a Garmin of some sort?

It’s not just superstition. Air conditioned air can be bad for you if you’re not maintaining it. It is also drying so it can bother your throat, eyes, and skin. It might make it easier to transmit COVID though that might just be in door air. I definitely prefer comfortable outdoor air to air conditioned air.

I feel that the vast majority of people should not need an elaborate setup to sleep well. If you need to spends hundreds or thousands of currency units on a setup beyond a basic bed, there is something wrong that could probably be fixed in a simpler way.

For myself I can sleep at any reasonable temperature. But between 60-65 F, I sleep extremely well. I do it with a relatively simple set up called an air conditioner, but I have fantasized about having a pillow that is always cool to the touch.
