Earlier quoted context omitted.

Quite randomly, regarding Turkey, I just watched the movie Midnight Express. Then watched Midnight Return right after. Only because I saw someone on HN talking about how many cats there are in Istanbul, and name-dropping the movie. Now I really want to go there. Without smuggling any hash of course. Crypto hashes are okay right? ;-)

have you watched KEDi? :)

I haven't but I plan to soon. Thanks for letting me know.

If it's too hot, I use a sheet. I think the explanation is pretty simple: crawly things that may come and bite us.

Blankets and sheets also protect from ghost, witches, monsters from under the bed... ask any child, if you're under something that hides you (or that you cant't look at), automatically you won't be found. Things that you can't look at can't look at you, too.

A CPAP doubles as an ideal monster snorkel.

A sheet over the head also protects against killer robots, as it interferes with face recognition. It also protects against alien abductors, as their paralysis-ray guns can't penetrate fabric with sufficiently high thread counts.

These days, I mainly protect myself from the spouse's dreaded fan, that constantly blows the icy breath of Borealis across the bed. But it's nice to be safe from all the monsters, too.

I'm not reading it because I don't sleep under a blanket on the hottest nights - can't relate.

I provide an explanation for why I'm not reading it, and you vote me down. Remarkable.

Since you are new to HN, you may not know this, but it is considered poor form to complain about being downvoted. And more often than not, it invites even more downvotes as a result.

From the HN Guidelines (which I recommend reading):

> Please don't comment about the voting on comments. It never does any good, and it makes boring reading.

If it bothers you this much, you're better off deleting your comment.

Have you tried out weighted blankets?

I've looked at them, they are mostly made of man made materials, I don't want to sleep with. The heat is also an issue, none I've seen address this. Cotton knit seems to be the best option right now.

Just use 2 blankets, 1 light 1 heavy, if you get cold, pull the heavy blanket over. No idea why people are down to a sheet and 1 blanket as a standard now.

Well, this is complicated. One of the linked studies shows the opposite result claimed in this article. This article says: " About 60 to 90 minutes before a usual bedtime, the body starts losing core temperature. There’s a physiological explanation for that: when the body is heated, we feel more alert. And conversely, when the body cools down, we tend to feel sleepier. Cooler internal body temperatures are correlated…

Presumably, there is an optimal temperature range for sleeping, and for healthy (not young/elderly/insomniac) adults, that temperature range is slightly below their normal temperature. That corroborates Tade0's comment below - observing that starting to feel cold at the wheel means the driver is in danger of falling asleep.

I've also embarked on long (16 hours at a time) drives, and can confirm starting to feel cold means I'm starting to fall asleep. But what I do next to continue being awake is this - I turn up the A/C. When I'm freezing cold, I can't fall asleep. Similarly, when I'm sleeping at night and the blanket has been ahem, stolen, by the significant other, I wake up from being freezing cold.

So back to the seemingly contradicting data -

>increase in skin temperature... shifts sleep to deeper stages (PLikely, these _ab_normal individuals are past the "comfortably cool" temperature perfect for sleeping and are instead too cold to sleep. Therefore, a thermosuit that negates that effect and brings their temperature back up to at least "comfortably cool" aids these individuals' sleep. The logic behind this also holds for the article's claim that babies (worse at thermoregulation) need more blankets.

I agree with your assessment of the research. But my point is that the linked article does not; it claims that the research used a suit which cools the participants, which is not the case. It, unfortunately, uses an incorrect understanding of the research (a cooling suit) to support a more well-established, true statement (core temperature drops around sleep).

have you watched KEDi? :)

Just watched KEDi on Youtube Red [1]. Made me cry. I love my cats so much but they live the best lives when they have the freedom. And I don't know how to deal with them getting sick or dying. With kids, you usually hope you are the first to go. But with pets that have shorter lives, how to cope? There is a lot of wisdom in the movie with regard to the special relationship and insight cats give us to life itself. I have such a deep respect for Turkey now, I even have new respect for Islam. Allahu akbar. May peace be with you my friend.

It's a weight thing for me, and not a warmth thing. I crave the feeling of something on me when I'm sleeping. Probably a sense of security. I've been on the eternal hunt for something heavy weight, and low heat. Currently using 3 x varying weights of knit cotton blankets, and does the job.

Oh man that's my dream. Something heavy that's not hot. I get hot very easily but I love the feeling of weight. I'm not understanding what you are using. You get the weight and little heat?

Damn, my wife is like that. I'm always cold, winter or summer. But i hate heavy bedding, and prefer light sheets and down comforters. But then, for many years, I slept in a nylon sleeping bag on a foam pad.

Got hit with an unexpected blizzard once when I was on an FTX in Colorado, in December. Pure freaking misery (slept in a mummy bag with a watch cap on). Never been so cold in my life, before or since. My right foot still starts to ache whenever I get cold. So, I live in Florida now. Usually sleep with just a sheet, until my wife steals it at 3AM and wraps it around herself 5 times so I can't get it back.

I had a Goretex bivvy bag for sleeping outside. And I carried both polyester and goose down bags, and a boiled wool blanket. So I was well prepared.
