I am a borderline narcoleptic. I can basically will myself to pass the narcolepsy test, and so I've had the diagnosis overturned. As a result of this, I have some experience with sleep studies and I received some information from doctors about sleep. This information should cause one to be a bit skeptical about the sort of "sleep hacks" that come up often on HN.
The test for narcolepsy I took consists for lying in bed the morning-after of the overnight part of the sleep test, and falling asleep 4 times. If you can fall asleep 4 times, and if you go too quickly into REM sleep every single time, then you are a narcoleptic. Narcoleptics can fall asleep very easily and tend to go very quickly into REM, but they do not go very easily into the deepest stage of sleep, which is the stage the brain uses to rid itself of certain materials. So narcoleptics have a bit of a problem. Often, we can get what many would call a "decent" span of sleep. However, we may only spend a couple of minutes in the deepest stage of sleep, where we might really want more.
I own a Zeo sleep monitor, and the data that I got out of it corroborated what the sleep studies indicated: I get only a fraction as much of the deepest stage of sleep, compared to the average for my age.
So here's the problem: These "sleep hacks" that allow you to enter into REM sleep very quickly for "power naps" may be harmful to you in the long term. You may well never enter the deepest levels of sleep that serves important physiological functions for your brain.

To be honest it puts the video above into practice requiring some level of accountability. I would recommend it for anyone who is procrastination prone. There are some really solid techniques (that are based on most recent science) that has already had some impact on my life.

I've always been jealous of people who are able to take power naps. I can't do it, unless I've done something exceptionally exhausting or I barely slept the night before. I end up closing my eyes waiting to fall asleep, and then nothing happens.

Try meditation. I guess you are not supposed to fall asleep while meditating, but the breathing exercises I learnt from meditating always helped me fall asleep.

I'm not usually one to complain about this… but wow, this site is incredibly hard to read on mobile, at least on an iPhone. Zooming out is disabled, too.

You probably didn't notice this on mobile, but this is google books. The poorly rendered text is due to it being an actual scan of some book. What exactly is being linked to here is unclear though. The passage isn't too concrete on getting a point across...

The short and sweet version (and heavily paraphrased) version is:
If you're tired in the afternoon, you only need a literal moment of sleep to feel revived. You can do this by sitting in a chair, holding something in your hand (a key, in this book), palm down, with something beneath it on the floor (a plate, in this book) that will create some sound when hit. The instant you fall asleep, you drop the item onto the the thing on the floor, it wakes you up, you feel energized.

She says Edison did the same thing too, but had a handful of ball bearings instead of a key.
Do it!
Now if you were falling asleep while trying to meditate then you might not be sleeping enough in general.
