During a nap you're not trying to lose consciousness as if you're "totally asleep" either. It's almost like you're hypnotizing yourself into a deep state of relaxation. A pair of sunglasses or sleep mask can also help to reduce any daytime light to make it easier.

Practice it for a year, you'll be an expert after that and have a highly valuable skill.

The sleep is worth the practice :)

The "trick" is to let you mind wander without intentionally thinking about anything, but just letting thoughts float on by without getting attached to any one of them. Just notice all the different things your mind is bringing up, and let it happen, without grabbing hold of any one thought.

My big problem is that I have a strong inner voice that is explaining or narrating almost all that I do. This voice if focusing my thoughts, so I need to stop talking inside my head for this to work. I kind of just need to shut up and watch my thoughts instead :)

I force myself to. I just simulate what happens when I really start falling asleep. I create random thoughts and I chain them as fast as possible.

Example:

If I break the ice with my hammer the calendar will fall on monday, but I have to escape from a huge mountain today, etc... Works super well for me. If I really need to sleep I'll use that technique, if I'm not sleepy I can do that for like 20 minutes, I have to focus not to think about something and just think about those random and nonsense stuff and I will fall asleep eventually.

I've noticed it is often preceded by having some thought, then 5 seconds later realizing that the thought I just had makes absolutely no sense. I guess that's the reality testing switching off.

The catch? if i had stray thoughts, i would have to start back at 1. I never get that far (101). But i always managed to clear my mind and fall asleep.

After reading about other people's techniques, it seems i stumbled on things like breathing and visualization.

In the same way pole jumping without arms or legs "just takes practice".

For me, when I stopped watching TV and doing things on my laptop from my bed, I very quickly noticed an improvement in how quickly I fell asleep.

Another big one is exercise. I notice that when I exercise I have a much easier time falling asleep than on days that I don't, I now try to exercise every day.

I also got older over the past few years, which in and of itself could explain things, so, I suggest experimenting to find what works best for you.

Edit: typo.

Watching TV, laptops, reading, etc... do not train your brain that the bed is for sleeping. Now I lay in bed for a nap and I will typically zonk out in a couple of minutes.

When I'm not sleeping alone, the other people tell me I'm snoring after 10min lying around. But I cant remember falling asleep, snoring OR waking up. Just That I had my eyes closed and tried to sleep.

So I guess, I cant check for my self that I'm asleep...

What's interesting is that I definitely feel like I'm perceiving the world with some continuity during that time -- I'll hear coworkers' conversations, people walking around, etc. -- but apparently I miss things like people coming up and checking if I'm awake, or even the time someone laid my hoodie over me as an improvised blanket.

If I sleep any longer than 90 minutes or so, I just perceive it the same way I do sleeping at night.

The brain is a strange contraption, isn't it?

It depends on the time of day. I can't exactly fall asleep on command, but I'll find myself longing for a nap in the afternoon, usually around 2 or 3. I can fall asleep pretty quickly then, and usually I'll wake up about 20 minutes later.

Does your awareness reduce? It's hard to notice a change in awareness. Sometimes I notice a transition from haziness to attention when a sound draws my attention. My understanding is that the haziness is a form of sleeping and is exactly what a nap is meant to be. If you fall into a deeper sleep you will get some of the side effects others talk about -- grogginess etc. The length and depth of sleep is related, so I thought that's why you need to be careful to only nap for short periods of time.

That then leaves enough to get 10 minutes or so of sleep and get back up 20 minutes after starting your nap. Much longer than that and you risk not getting up for another few hours.

Much less than that and you won't get any rest.

And yes, this works perfectly well even without falling asleep. Just lay still for 20 minutes and let your mind wander without distractions or worrying about what you're thinking about. Congratulations, you've just meditated.

I have a lot of anxiety, which I imagine is relatively common among the developer and tech community. Sleep and peacefulness does not come easily to me. I've tried taking naps at various points over the years, but haven't successfully taken one since I was about 12 or so. Sometimes I'll even lie in bed for 30, 40, 50 minutes to just try and take a short nap. Eventually I'll give up and wonder why I wasted all that time.

This will happen to me even if I'm extremely sleep deprived, and feel very physically and mentally exhausted.

Nope, well over an hour is my average. And that's at night in my bed after a full day work.

I think the most important thing I did was defining that taking one hour to fall asleep was problematic and then tackling the problem methodically. Seeing a doctor about it was on my scope had I failed to solve the problem on my own.

Just. I've never been able to do that. I'm always thinking, even when I am exhausted. (Usually then, about how exhausted I am.)

Otherwise known as "lettings your mind wander". Just go with it, you don't have to not-think. It is perfectly fine to spend 20 minutes laying down and thinking.

Too interesting and you get wired. Too dull and your mind begins to wonder. Some work so well that it takes me several runs to listen completely.

Until I discovered deep meditation (http://www.amazon.com/Deep-Meditation-Pathway-Personal-Freed...). Summarized: Repeat a chant, such as 'I am' (or any phrase of your choosing) for about 5 minutes, focusing on what the chant-phrase sounds like in your mind.

With the phrase 'I am', you would try to feel the sounds 'A-Y-A-M' being pronounced in your mind, without ever vocalizing it.

Gets me napping within 5 minutes, wake up charged up for a massively productive session. I hope you'll give it a try sometime.
