Disclaimer: I'm going to reference a product I built. The science of sleep is a strange thing. Sleep is ubiquitous (after all, everyone needs to sleep), and almost everyone I know complains of being tired, or constantly groggy, or stressed due to the limited amount of sleep that they get every night. I know this particularly well, because I suffer from mild insomnia that keeps me awake far later than I should be. I t…

This sounds like a gross oversimplification. For one thing - even if 90 minutes is the average length of a sleep cycle, this surely varies between humans. My sleep cycle might easily be 80 minutes or 100 minutes long, rather than 90. If I were to use sleepyti.me, it might recommend that I go to bed at 11:00pm to get up at 6:30am. But if my sleep cycle is only 80 minutes long, it will be 40 minutes out in its recommen…

When you first posted about sleepyti.me here on HN, I was enduring a long phase where I was having a particularly hard time falling asleep at night. I would often lie in bed for two or three hours before I finally drifted off. Compounding the issue was my tendency to constantly measure and analyze how long I'd been trying and how much sleep I would (not) get if I fell asleep "now", always comparing those figures with…

I've adopted a biphasic sleep pattern of sorts by chance. It started by occasionally falling asleep when putting my son to sleep, and when I'd wake up I'd compensate by staying up longer. After a while I realized it works very well for me to got to sleep for a couple of hours around 8 when he goes to sleep, and then stay up for a few hours before going back to sleep - I usually feel very mellow and relaxed when wakin…

I did this for the first two years of college-- I'd often sleep for about 3-4 hours each night before class, and then sleep another chunk of time in the afternoon. However, it had the opposite effect on me as it became more and more difficult to go "back" to sleep in the afternoon unless I waited until the evening. What ended up happening the last year or so is that I started sleeping 5-6 hours per night without a na…

Earlier quoted context omitted.

If you don't mind the question: what kind of activity do you need to have in a site to generate that kind of revenue from it? ($ 1500 - $ 2000). Is it something in the order of, say, 10k ad views per month, 100k, or something bigger like 1 million, or is any other interesting factor that needs to be considered?

I'm not the OP, but I've been running ad-supported sites since before the dotcom crash of 2000, so hopefully I have some useful insight on this. As an extremely rough benchmark, assuming $1 - $2 per 1000 page views on most sites is a reasonable baseline. Not all sites will be able to get to this, and some will get to far more, based on monetisation methods, ad placement (VERY important and frequently undervalued), nu…

So if you're used to sleeping for eight hours at a time...should you set your alarm for four hours, wake up, do something sedate for a while, and then go back to bed? Should it be more like 4.5 so that (in theory) it happens at the end of a 1.5-hour sleep cycle?

I don't think you should set an alarm ever if you can help it. If the theory is that bi-phasic sleep is ideal and natural for us, you should fall into that pattern naturally. All you need to do is go to sleep around the time that the sun goes down. It's just that "easy".
