Why Do We Sleep Under Blankets, Even on the Hottest Nights? (2017)

Neither does anyone else, its one of those archaic units that changes slightly based on who is using it and hangs on in oil and gas industries, and also air conditioners and heaters.
It was defined as the amount of energy to raise one pound of water by one degree Fahrenheit at one atmosphere of pressure, but that amount of energy depends on the starting temperature of the water, and different things use different starting points, so it ranges from about 1054 to 1059 joules
(editing to add - I didn't realize that water's specific heat has a temperature dependence and changes around 5% over reasonable indoor temperatures

What does that have to do with a perfect gas?
> Why would the amount of energy required to increase the temperature of a defined mass of water depend on the temperature?
and the answer is that it does, except if you have a very restrictive model where it doesn't. (Edit: I see there was an edit to the previous comment, I had missed that.)
Why does water relate to the ideal gas law?
There's an issue right there and one that cracks the door open to "how is pound of water created".
Leading into (depending on path to above) the issue of density of water, while famously and often described as incompressible, water reaches max density at 4 C, 3.99 degrees (Kelvin or Celsius) above water's triple point.
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 statements in anthropology, psychology, etc when an author wants to hold up some supporting example about a group of people they are not experts on.
We don’t have to cure them, nor be cruel in our handling of people. But we also don’t have to pretend that autism is the most ideal state to thrive in human society. Language needs to define terms, and at some measure of sensitivity they are going to sound insensitive.
Again, we don’t have to be cruel. But we can help, or treat, or alleviate, or accommodate for the symptoms of autism. You pick the word that’s less depersonalising, keeping in mind that any word here is arbitrary.
Autism isn’t a brilliant condition and we can all hope to make the lives of others better. If that means using softer language, I’m all for it; yet, some language has to be used. And, perhaps, if we could treat autism itself, we might want to give people that option.
Is this an American thing? Do people in warmer regions of the country (Texas, Florida, ...) also feel the same?
The best mitigation for this conflict seems to be those knitted blankets with the enormous holes. Terrible heat retention, and they're pretty heavy. That got the job done during a Texas summer on more than one occasion.
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

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).
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 remove the blanket when they get hot.
But if you are so used to blankets that you can’t fall asleep without one, dropping the blanket because it’s hot is a pretty bad sleeping strategy
I don't know what TFA is talking about.
There’s some videos out there of people in warm climates sleeping with no cover.
Humans are funky.
2. You are from florida, where there's an entire species of insect for every sqr centimeter of the body, and enough mosquitos after 19:00 to write each of them through displacement.
3. Ideal sleeping temerature is probably so close to 'perfect' that as body temp drops through sleep, it crosses the thin threshold of comfortable to slightly cold.
Since we've abandoned the penny, I hope that rounds up to a nickel of thought.

They use worse weaving machines which go quicker causing a worse texture, fibers also really limit the weaving. You'd genuinely have to feel to understand the difference. The edges/'insert part' will also be more refined.
Your linen sheets will be washed more thoroughly before using when you buy luxury linen. Luxury brands will be more strict quality control.
This doesn't mean the Ikea ones are improper but there's a reason people pay more for quality products, these products tend to be made in countries with higher labour costs as well (Belgium, Ireland, Italy, Baltic countries ...). All my bedding comes from Libeco in Flanders and most of my linen clothing comes from "Not Perfect Linen" in Lithuania which is affordable considering it's custom made.
If I remember correctly, it claim is that about 50% of all labour over the course of history has gone into making textiles. More than food!
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 much of that is nature or nurture as well.
In my case however this has persisted well into adulthood: despite being a chronic insomniac who has a really hard time falling a sleep normally, at these types of social gatherings I often have to fight off falling asleep precisely because I feel comfortable and safe among friends and/or family (I wonder if that is in any way related to my ADHD).
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.

Extremely comfy.
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.
At least thats what I tell my kids.
