And here's an excerpt where you repeatedly say that modern sleep is unnatural.

> Modern sleep, in its infinite comfort, is an unnatural superstimulus that overwhelms our brains with pleasure and comfort (note: I’m not saying that it’s bad, simply that being in bed today is much more pleasurable than being in “bed” in the past.)

> Think about sleep 10,000 years ago. You sleep in a cave, in a hut, or under the sky, with predators and enemy tribes roaming around. You are on a wooden floor, on an animal’s skin, or on the ground. The temperature will probably drop 5-10°C overnight, meaning that if you were comfortable when you were falling asleep, you are going to be freezing when you wake up. Finally, there’s moon shining right at you and all kinds of sounds coming from the forest around you.

> In contrast, today: you sleep on your super-comfortable machine-crafted foam of the exact right firmness for you. You are completely safe in your home, protected by thick walls and doors. Your room’s temperature stays roughly constant, ensuring that you stay warm and comfy throughout the night. Finally, you are in a light and sound-insulated environment of your house. And if there’s any kind of disturbance you have eye masks and earplugs.

> Does this sound “natural”?

Ouch. Ambient sounds of the forest are a lot better than the modern equivalent of loud neighbors and drilling. He also seems to have forgotten that humans built fires. Caves have great sound insulation and I'm pretty sure our ancestors knew how to choose their caves.

I have spent years being a sleep deprived student because the dorms were super noisy with random parties and paper thin walls so I really can't relate to the implied utter comfortable sleeping habits of modern people. I'm sure there are people complaining about noise pollution in NY as well.

No one in my circle sleeps on an overpriced mattress. Mostly it's just the bed the place that we rent has. I never could connect with articles implying modern people live in these utterly comfortable utopias when it's really not the case. People are depressed. Especially males are doing horribly.

A few years ago I bought a mattress for less than $100 from Amazon to sleep on.

While it was funny to complain about how uncomfortable this cheap mattress was, it was still an extremely luxurious piece of technology unfathomable to any cave dweller.

It doesn't seem so crazy to me to wonder whether modern mattresses like these are incentivizing us to sleep longer than what is optimal.

[James_Henry]

People have research modern pre-industrial societies and while they do have fires and nicer sounds than drilling they don't sleep in caves. Also birds are really loud sometimes.

I don't think you'd want to sleep in their circumstances over yours, but maybe you would. I for one like camping quite a bit even though I do usually get much less sleep while camping because I'll stay up late around a fire and then wake up at sunrise. I'm sure that'd change if I were out in the woods for more than a week.

Also, maybe your not-utterly-comfortable utopia is making people, maybe especially males, depressed!

Yep, and here's conclusion of this argument:

>Now, what if the only sleep available to you was modern sleep?

> 1. If you don’t sleep at all, you go crazy, because some amount of sleep is necessary.

> 2. If you sleep just enough to be awake during the day, you’ll be dreaming of getting a nap at the sight of a bed and will be distracted and sleepy all the time. Importantly, I claim, in this situation, the feeling of sleepiness does not mean that you should sleep more – it’s your brain being overpowered by a superstimulus while being bored.

3. I claim that if you sleep as much as you want, you’ll probably sleep too much and become more susceptible to depression. [by analogy to eating too much]

- And if you sleep way too much at once, you’ll be feeling terrible afterwards, however pleasant the sleep was.

[dreig]

You may attempt to apply the same analogy to drinking water, and see that it doesn't work. If you drink as much as you want, then you'll probably drink too much (with whatever negative consequences arising as a result). But, except for some extreme circumstances, I don't think people drink much more than is necessary to quench their thirst.

That is your conclusion might still be correct, but it doesn't follow from the analogy with eating.

[Zababa]

The thing is, the experience of drinking water has not changed much compared to before. However, if you take all beverages, you'll see that lots of people drink too much soda, and it's not to quench their thirst.

[RandomThrow321]

Water has changed dramatically. Think of all that goes into modern sedimentation, filtration, and disinfection - not to mention treatments for hard water or additives like fluorine. The taste is better because of the mineral content, and we can even add carbonation!

[Zababa]

That still doesn't make it a superstimulus. The difference is not that big in terms of stimulation.

[guzey]

Is drinking modern water a superstimulus like modern junk food from my analogy is?

[cardine]

You are conditioned to overeat because your body can store the excess energy in the event of future needs.

The body is expecting such a future need as in our past there were often periods of food scarcity. Since in our modern society this food scarcity doesn't exist, the body overconsumes, preparing for a future that will never come.

We do not have such a mechanism for storing infinite water, so we do not crave an overabundance of water.

I think you are thinking about sleep on the wrong axis. It is not whether it is a superstimulus; it is whether your body can store an abundance of it for a future anticipated need.

I would argue in this case, sleep is much more like water than food in this way in that there is a very small amount of sleep (possibly zero) your body can effectively stockpile.

[RandomThrow321]

Why is sleep a superstimulus but water isn't?
