#62Recently discovered that "weighted blankets" are a thing. https://en.wikipedia.org/wiki/Weighted_blanket
I love weighted blankets but have to be careful that they're not "too" heavy. I used to have sleep paralysis relatively often as a kid and a too heavy weighted blanket often re-triggers this, which is obviously terrifying.
If not for comforting my neuro divergeny, I also love it for staying put and not dropping off of the side, or foot, of the bed and falling on the floor.
Only caveat is getting it into the sheet covers. That is hard work lol, quite the workout. Considering skipping that part and just putting it on top of a light bedsheet.
I add a warm, thick blanket on top of the weighted one if needed, e.g. in winter.
It's important to stack it that way. Putting the weighted one on top keeps everything put, but the compression on the warm blanket negates the temperature isolation and it gets cold quick.

That would result in insanity for me. Is there any argument other than it seems like cave people must have?
Not just you. Most are insane already. Temperature, noise, light, other partner, pillows, ventilation, caffeine, wind down (including me as I write this comment) - majority of people mismanage this so badly. We spend 1/3rd of our time on it, it's probably top 5 of most important things in our life, yet we butcher it so badly.

#64Is this a common thing? Sleeping without any sort of cover during the hot summer months (notably July and August) is the norm here (North Africa) and never heard of anyone who does it (AC or not). Is this an American thing? Do people in warmer regions of the country (Texas, Florida, ...) also feel the same?
As someone who lives in the Northeast US but travels to Florida somewhat regularly it amazes me how low people keep the AC. It’s common for people and places, or at least those I visit, to keep the AC lower than I keep my heat in the winter(18c). So sometimes I’m so cold I have to ask for additional blankets or bring a jacket to a place like a movie theater.
Humidity does a lot.
As I've posted before:
115C with 10% humidity (71.66F wet bulb) here is hot, but as long as you have water, you're better off here than in Florida with 85F at 90% humidity (87.46F wet bulb).

Yes, it is totally a thing. We don't have a lot of hot nights in Denmark but when we do, we still sleep under a duvet, or maybe half under one and it is just as awful as it sounds.
Are you sure? That seems like the sort of thing people might just not do. It can't take that many brain cells for an uncomfortably warm person to work out that more blankets make you more hotter -> less blankets makes you less hotter. The article seems to provide very limited evidence that people sleep under blankets on hot nights and it sounds like a silly thing to do in the abstract. A lot of people would just remo…

Well, this is probably a thing where humans are very diverse in their subjective experience. I'd say this is definitely a noticeable thing with small children at family gatherings, birthday parties and the like. But I grew up in a household where both of my parents came from families where big family gatherings with even extended family was common, and I know not everyone has that kind of experience, so who knows how…
It's the food and air quality. There's a lot of people in an enclosed environment eating too many carbs (or too much in general).
Timing is critical and I'm on a mission. Before the heavy food comes out, I grab a seltzer and a small salad. I convince some people to join me on the patio for a drink. It's important to arrive late enough that people are eager to break away, but well before any food ceremony.

Folks in the South don't consciously realize it, but they're setting the AC low to keep it running for its dehumidification. These are the same folks who sweaters is its 80F outside. They can handle heat. If ACs had the ability to run as dehumidifiers in convinced the temp would rise
If it's less than 80 outside it's cold. If it's over 69 inside then it's hot and I can't sleep -florida man

#68> there has also been a decent amount of research about the calming effect of weighted blankets, which can weigh up to 30 pounds. Studies indicate that they can curb anxiety and even be used in the treatment of autism. What odd phrasing, "the treatment of autism". Wouldn't it suffice to say a lot of autistic people find them comforting? This may just be my bugbear, but I notice a lot of these depersonalising statemen…

They're not saying the rate varies but the starting point. Going from 30C to 100C takes less energy than going from 20C to 100C even if specific heat remains physical. Both might get labeled a BTU.
They specifically said "one degree Fahrenheit", so the GP's question was "why does going from 30 F to 31 F take a different amount of energy than going from 20 F to 21 F?".

Well in the later scenario the water would be frozen and conduct heat within the volume poorly, so applying heat would result in a phase change at the contact point. Latent heat transfer is then going to complicate things.
