Sleep rocks! I am in the 2.5% that sleep 8 hours or more. I am much more productive during the day as a result. I am alert, my brain spins faster and I can take on more challenges. My friend is a superstar scientist/M.D. and he sleeps 9 or more hours a day.

The "executives" who sleep < 7 hours need to fine a hour more. If I was a board member, I'd insist my C-level team sleep 8 hours!

Sleep may be more important than food but, interestingly, there seems to be a relationship between sleep and food. When fasting, less sleep is required. However, when sleep is curtailed, there is a greater desire for food.

I always figured if you're awake instead of asleep, you're actually consuming more calories and thus need more food.

Something I observed from reading the comments here:

A lot of us can function on much fewer hours of sleep regularly and don't believe it adversely affects our performance (It does affect mine though). Does anyone think there may be some selection going on here?

What I mean is, perhaps it's true that HN's distribution is more skewed toward the side of people who need less sleep (and hence has more productive hours in the day) and are willing to sleep less in order to get things done. Maybe we don't really represent the general population.

Just a warning in case anyone takes our testimonials too seriously.

"Procrastination and heroic effort at the last minute were the norm." This may be true, but there are also plenty of students who work from the moment they wake up until the moment they go to bed and still don't have enough time to get all of their assignments done. The problem is that functionally there isn't really any difference between having a 3.5 GPA and a 2.0 GPA, so at some point most people figure out that w…

Perhaps they should have gone somewhere else where they had time to sleep and think instead of just studying all the time. I know that where I work, the folks who are willing to grind the hardest on assigned work are rarely the ones you turn to for difficult and responsible work. The very best people are the ones who work extremely hard at self-directed work and sometimes push back against assigned work, but they are…

I can't agree with this more. However, whenever I refuse to do work I get stamped on the forehead with "lazy". For example, I figure out that the homework in a class is 25% the grade but there are 25 of them, so each is worth 1%. I understand the topic so I figure that it's a waste of my 4 hours to do the work for 1% extra. Bam, "you're so lazy".

I'm surprised this article is at the top of HN. 1) It is not the announcement of a research study, rather it is just referencing previous hbr blogs and sleepfoundation.org's general guidelines for sleep. 2) It offers no unique advice. 3) The title is basic linkbait (ie, its not really about food vs sleep). Why the upvotes? is it because everyone is tired?

It may not be new or unique, but I didn't know sleep was that important.

And no, I'm not tired.

Even more disconcerting is the sleeping culture/routine throughout medical residency and fellowship; arguably, the most important stages of medical education, where doctors in training learn the hands-on skills to practice medicine. Despite the importance of learning during this stage, individuals are routinely sleep-deprived: "20% of all residents reported sleeping an average of 5 hours or less per night, with 66% a…

To some extent the sleep deprivation is a weeding process/learning experience in and of itself. Being able to perform under stress/lack of sleep is a good quality in a doctor.

How many doctors are actually weeded out after they get to their residency, though? First year of med school, absolutely. Residency is a bit late.

Everybody thinks they are above average. "I can exceed the speed limits, because I am an excellent driver." "I need less sleep than the average person."

Schools such as Caltech and MIT have rigorous curricula that proverbially requires constant study every day of the week just to stay in the middle of the pack. Naturally, most students cut back on sleep. Proponents of this approach are aware of this, even boast about it, saying that this is the best way to learn the material. On the other hand, numerous studies -- including the link at the top of this page -- conclud…

I excelled when I was a MS CS student at Stanford (I can go into detail if anyone needs convincing), and I did it on very little sleep - 4-5 hours/night for weeks at a time. I absolutely positively couldn't have done what I did on 8 hours of sleep a night. There wouldn't have been enough time in the day.

I sleep much more now. Left to my own devices, I adjust to a roughly 28-hour clock during which I sleep 9-10 hours a cycle.

One thing that I wanted to try (but never had the schedule to support) is polyphasic sleep ( http://en.wikipedia.org/wiki/Polyphasic_sleep ). The idea that sleeping 15 minutes every 4 hours (on a very strict schedule) to keep your mind close to a waking-REM-type sleep. Granted, every few weeks you would have to crash HARD (20+ hour rest).
