Every cycle has a rhythm to it, its own cycle. When I wake from a early morning nap (midnight - 7am) I usually start out a little tired, still wanting for sleep. That inevitably passes if I get up and start engaging my brain in something trivial like washing dishes or watching a tv show. Alertness follows for anywhere from 10 minutes to 3 hours. Eventually it comes back down, leading me back to sleep.
The sleep has its own cycle, from lying down to mental chatter, to unknowingly falling asleep, to deep dreaming, to non-REM unconsciousness, to gentle awakening. An alarm clock can interrupt anywhere in the middle of this, dictating the flow of the next waking cycle.
With the knowing that the tired feeling will pass if I just start moving, I now feel it's much easier to get up. I avoid productive work until the tired feeling is gone and replaced with alertness.
Somehow daytime is much different. It's more like one long cycle with just one peak and trough. It used to be more like night. But with the naps thrown in there it's actually much better than before. I don't know what I was ever thinking...being awake for 16+ hours with no sleep? No way. This is so much better.
Been a while since my last post. I'm still on it. I had a falling out around Thanksgiving with 3-4 days of extreme oversleeping. Where I'm at right now:
I tend to oversleep daily. Just random times. Seems out of my control. Like I will sleepwalk, turn off my alarm, go back to sleep. Or randomly fall asleep at my computer, or find myself in my living room, very confused as to what's going on and what time it is.
I'm usually really exhausted and out of it at 6 am-10am, and then feel fine after 11am...almost like clockwork. But then I will oversleep at other random times when I actually feel okay, like 2pm.
Along with exercise and nutrition, sleep is one of the primary determinants of your happiness and wellbeing. If you don't get good sleep, you will not only be tired, but also pessimistic, unmotivated, lazy or even depressed.
Research has shown that self control is a limited resource that is greatly diminished when you're exhausted. If you don't get good sleep, you are less likely to be productive and stick to your good habits (such as exercise). You are also more likely to do things that you know are bad for you (such as eating sweets).
Good REM sleep plays a critical role in the development of long term memories. If you're trying to learn anything at all, you better make sure you get enough high quality sleep.
Proper sleep is also essential for maintaining a robust immune system. If you want to be happy, healthy, smart and productive, you have must make sure you get good sleep.
Do you think that your physical health and emotional wellbeing can be considered in isolation? Think again. They both come from the same body, and they both require that you sleep well.
