I'll weigh in as a no. Sleep deprivation sends me to the other end of the scale. Hyperactive, chipper, gregarious, creative and it's great until I hit the wall and pass out. Generally wake up bleary, but still in incredibly good humor.
Might be of note that I do have mood issues, had prolonged and serious insomnia problems and tend to react in reverse to sleep medications, exhibiting similar behaviors as above, only less.
You'd need to give me a better concept of what you're talking then. An average of three hours of sleep per night with a twelve hour crash once a week for six months is the closest I could come to a continuous cycle. And yes to that.
Weeks? Not entirely without sleep. Three days, yes. And the worst I ever got was incoherent and blank. Not depressed.
Same here. Unemployment and being out of school make it worse, because no matter how tired I am, my subconscious is still responsible enough to get me to work or class most of the time, whereas having no obligations to wake up for leads into an ongoing crepuscular or nocturnal routine.
I believe it's been shown (and my own experience bears out) that sleep deprivation by itself is usually a fairly effective antidepressant. Of course, most of the things that cause sleep deprivation (aside from, say, speed) are pretty depressing.
Less than six hours of sleep and I'm not very nice to be around...have trouble smiling and get caught up in my own b/s a lot faster than normal. It makes me want to buy into the power struggles at work and scarcity.
four day so of very little sleep and i'm ready to go postal. it's a feeling of anxiety, upset, anger and serious sadness...a lot like passionate grieving. sort of makes nap time when we were young make a lot more sense.
IIRC from medical research type info, sleep deprivation over any period can lead to depression, although usually it takes more than one night. One night of dep can lead to emotional lability and fragility, mood swings and irritability.
Me personally? Lost sleep = emotional lability. Loss of sleep over a few days equals serious crankiness and depression conbined. (Mitigated thankfully by being on antidepressants, but they can only do so much when I haven't slept.) The sheer misery of insomnis is, well, misery-licious. When I get to be in charge of Hell, insomnia is going to be the new punishment on some of the upper levels. Too many people enjoy pain.
A ridiculously high percentage of Americans are underslept on a regular basis.
People's sleep needs, REM periods and so on are individual and can vary pretty widely.
Depression can also lead to sleep disturbances; one of the "warning signs" for depression is irregular sleep and insomnia.
It can also vary depending on how one "treats" one's sleep-dep. Tons of caffiene? Irritability. Lots of sugar? Emotional lability and crashes.
Not generally for me, but sleep dep will generally accelerate mood changes and makes me emotionally fragile. So if I'm prone to being depressed for other reasons, sleep dep makes the depression worse. If I'm happy, I might get extra giddy-happy. The poorer my sleep, the more pain I feel and the stupider I get.
It can be argued that I react to sleep dep differently from other people, though. Given that I haven't actually had proper sleep for years, and my 'better' sleep now would count as bad for myself prior to this and for most other people, I'm deeply thankful that it doesn't make me depressed!
I hope you start sleeping better soon; sleep is beautiful.
Me, every now and then (it's not a regular, cyclical thing, it's just something that occasionally happens, probably due to external forces), I'd get kicked into this fucked up spiral. I would start having bad nightmares (always coupled with panic attacks during the day). This, of course, leads to insomnia, which leads to sleep dep, which leads to a really nasty depression. Eventually the whole thing would culminate in a crippling migraine which, though painful, actually forces me to get some sleep, and I start coming out of the whole mess.
I caught on to this little cycle about two years ago, and now I'm starting to be able to catch it early -- when I notice the nightmares/panic attacks getting bad, I counter with stuff that'll help me sleep anyway, so I don't get kicked into the rest of it...because the big key to the whole thing seems to be sleep (big shock there).
There's been a number of studies to suggest that depression and irregular circadian rhythms go hand-in-hand. An unproven study tries to show that if people get on a regular sleeping schedule they can diminish the effects of depression.
As mentioned before, there's the chicken-or-the-egg factor here.
With me, over a large period of time, it does tend to make a significant difference in my depression or lack thereof.
