According to Matthew Walker's book "Why we Sleep", sleep deprived people think they thrive. https://inweb.notesalong.com/id/5d785df04818060013b15a78/htt...

Sort of a dunning Krueger for sleep aptitude

Optimal or not there are plenty of people in society who are doing just fine on <6hr of sleep every night.

The results kind of speak for themselves. These people have jobs, families and generally productive lives like everyone else. If these people felt the extra sleep made their lives better than the extra time to do stuff they'd probably sleep more.

Yes, but they are deficient in many aspects without realizing it. For example, Alzheimers is almost certainly a condition caused by chronic sleep deprivation. The results don't speak for themselves at all. Read Matthew Walkers book and you'll have a better understanding of why we need 8 hours of sleep, and anyone saying otherwise is frankly misinformed.

I usually sleep around 6hrs on workdays. I need around 3-4 coffee / day, but not more :) I usually go to bed at around 2-3AM and wake at 8:30AM.

I can manage a job, side projects, girlfriend and social life. I'm not sure when will it hit back if it will ever.

There are Yogis that claim they can thrive on 2.5 hours of sleep, and that they've been doing that their entire life.

I don't think he addresses this subject in the book or in his talks, but it would be interesting to know his opinion on the subject.

There are also yogis who claim they can levitate, read minds, or bring dead babies back to life. Some healthy skepticism is in order.

You don't need to be a yogi to do those things. There are men and women (even kids and teenagers) who can read your mind like a page. Advanced ones can know what you're thinking before you're even aware of what that thought is. And they don't even have to be looking at you. It's 360 degree vision. Distance is no barrier. People who can read minds know to respect your space, because they know it's against spiritual law to violate your psychic space.

People who have developed the ability to bring the dead back to life will not do it, because they know there's a reason why somebody had to die. Why mess with the cycle of life?

Well yes, you see i can time travel, but I don't want to break causality. So I won't use my power. But you said worship me and give me money, because I time travel!

That must be terribly reassuring to the families of car crash victims.

You can make all the extraordinary claims you want if you never have to prove it, and no one should believe you until you do. You're basically just wasting your breath and letting everyone know you believe in fairy tales.

But maybe there's a reason why an automobile accident happened in the first space. Live is not just made up of a series of random events.

You can make all the claims you want. Everything is being made as it goes along, and if someone claims to have these powers and doesn't use them, they are either lying, deluded, or terribly cruel. It's awfully convenient, and really a sick joke, if the moment one has real agency, they can't use it.

Yes, and tons of people fall for that. They're up there with those other yogis who "don't eat food" (e.g. "Prahlad Jani is an Indian breatharian monk who claims to have lived without food and water since 1940"), perform magical tasks, and so on...

There are yogis that claim that they can live off air alone, until their grandchildren are caught sneaking them snacks.

I doubt those yogis work in STEM.

Not much need for sleep if all you do is meditate

Re:Can genetics explain why some people thrive on less sleep? by mping on Wednesday September 11, 2019 @04:03AM (#20937607)
Clearly you haven't meditated all day. I assure you, it is tiring.
Re:Can genetics explain why some people thrive on less sleep? by jack_pp on Wednesday September 11, 2019 @05:52AM (#20938160)
I started meditating 9 years ago and do yoga once a week and am pretty sure that if I made a lifestyle out of it i could reduce sleep need however I suspect the hours of sleep I gain will be used to meditate so in the end you don't gain that much in terms of free time per day.

You might be more productive per minute after meditating but that's another discussion

Re:Can genetics explain why some people thrive on less sleep? by mping on Wednesday September 11, 2019 @06:58AM (#20938625)
I do agree with you, whenever I meditate more often I sleep less. Also, I end up "gaining" time because I pay less attention to distractions/time wasters/procrastination.

However, in my experience it takes years before you may comfortably spend all day meditating. I'm pretty sure most of meditators, teachers or otherwise, are not able to do this. It's extremely demanding, it is only boring if you don't focus properly.

I've participated in retreats that start at 2h30AM and end at 00H00 every day, with 1h sits and 20m breaks in between (same routine over 3-7 weeks), and only a handful of people are able to follow this schedule. Even meditation "only" on a 9-5 schedule is hard.

My original reply was hyperbole. I did not mean they literally meditate all day. I meant that a day in the life of a yogi is very different than that of a normal person let alone a western one so their required sleep time is irrelevant to the discussion

I see; I have a hard time picking nuances over the internet. Thanks for the clarification.

Sure, and yet it's entirely different from solving hard problems.
Re:Can genetics explain why some people thrive on less sleep? by coldtea on Wednesday September 11, 2019 @06:09AM (#20938266)
Only if you do it as a westerner / novice.

For people doing it in their culture, from a young age, it's second nature...
