Why?
I have realized over the years that I need to be seriously cold to sleep well. My health watch always registers a great sleep and recharged "body battery" when I've been almost shivering all night. My partner likes to joke that my body needs "suffering to get fully rested".
These days, I only ever have nightmares when I'm too hot. It's a challenge to stay cool enough to not get them.
I did recently switch mattresses to this Airweave Futon: https://airweave.com/products/futon
It's an amazing product, it helps keep me cool, and is nice and firm, which I need to have a restful sleep without back pain. By far my favorite mattress I've ever used.
The Airweave has reduced my hot nights significantly, and I'm thinking if I can put a cool pad underneath it, I'll be set!
I'm going to have to try this DIY project for sure now!
I would think these would be too loud for a comfortable sleep environment.
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 nothing.
For reference in 2022 I winter hiked the southern half of the AT, and it was below freezing every night for months. I did have a sleeping bag, but I slept great! I curse/blame my Scandinavian genes. Too pale for the equatorial sun and sleep like a furnace all night.
Would you mind sharing which watch (model) offers this? I guess a Garmin of some sort?
I got it a year ago, still feels like new. However, I got the very thin Japanese futon model, and my partner and I are both under 145lb/65kg so that probably goes a long way. I could definitely see a heavier load compressing the coils permanently.
I did see this on their FAQ page:
"Up to what individual body weight is ideal for an airweave? We have tested our mattresses for individuals up to 220lbs. At this weight or lower, you should expect to use your mattress for 10-15 years. For any individuals above 220lbs you may see body indents and wear sooner"
I also see that the warranty is good for only 3 years for the futon model, which leads me to believe I'll be shopping for a new one in 2 years. That's... Not a long time for the fairly steep price of $2600.
When this wears out, I'll probably go back to a thin cotton futon, that's my second favorite. I only got the Airweave because my last cotton futon got moldy because it's so humid here it never gets to dry out.
It is both confusing and fascinating how some companies manage to put out a product with a subscription, the existence of which defies logic and consumer expectation, and yet they manage to find a group of people who tolerate it.
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 income. You can now make money twice.
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
A good spring mattress sitting on top of slats will never get uncomfortably hot or cold in any particular spot, because air moves freely in and out, powered by your own body movements.
The mattress should also be as firm as you can tolerate. A firm mattress leaves breathable space between some parts of your body and the surface of the bed, instead of allowing your body to sink into the foam and become insulated on all sides. Again, airflow is key. Regardless of what heating or cooling solution you have, airflow will multiply its effect.
If you want an all-natural, chemical-free, traditional hand-made pocket-sprung mattress you’re looking at £3-6k here in the UK. But I agree they are the pinnacle of mattresses, ticking every box
Synthetic fibers can be designed to channel moisture away from your skin instead of trapping it, but they can't absorb any. Besides, I doubt that hotels use sportswear-grade stuff in their duvets.
I'm apalled by the fact that in 20 years we have regressed rather than improved on the temperature aspect of mattresses
I do a cold shower before bed. Often helps.
You can start the shower warm and then slowly reduce the temperature.
I lived most of my life in the Mediterranean country and lived in a apartment on the top floor with just a concrete roof where the room temperature was 34°C even at night.
The solution I found was to take frequent cold showers. Stay under the shower for some time, like 5-10 mins, until you get cold, and then without drying yourself, lie in bed naked. I also felt so cool that I even put a blanket over me. It takes a while until you get warm again, so it's enough time to fall asleep.
For more extreme hot situations you can put a wet cloth/t-shirt on your body, but I think that might be unhealthy.
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
Anecdotally seems true for me, but I also have poor circulation to my extremities so I just suffer one way or the other.
We evolved in places that were hotter [0] on average than where most HN commenters reside.
[0] ... unless paleoclimate in Africa was much colder than I guess it was.
I think that’s what this is for? I love a cool bed on a warm evening
