Happens to me every time with a long nap, especially if I ate within about 2 hours of falling asleep. Some mild research seemed to point to something called "Positional Vertigo", but I never did really look into it.
 
Not sick, but more tired than before. So, sometimes I don't even take a nap if I don't trust that I won't wake up quickly enough. Sometimes, I nap a tiny bit just to loose the "sleepy" feeling.
 
Not sick but out of it. Only sometimes, though. If I didn't get enough sleep the night before a couple hour nap leaves me feeling out of it for 10-15 minutes then ok.
 
Yes, I will feel sick for the rest of the day if I take a nap longer than an hour. It takes me at least an hour just to feel "awake" again then I usually have a stomach ache and feel bad for hours. As you can guess, I never take naps.

Something similar happens if I only get 2-3 hours of sleep at night. I feel better getting no sleep at all than 3 hours.
 
I will get a headache if I nap for too long. I would rather stay awake and be tired until night comes rather than nap, unless I am doing some physically tiring work.

Sleep Inertia. You guys are waking from deep sleep. That's why a recommended nap is about 15 minutes; not enough time to enter deep sleep.

I don't take power naps, but I do "rest my eyes":rolleyes: and meditate. Nearly the same benefits as a power nap, without falling asleep.
 
What Mousse said.

Maximum length of a power nap should be 20/25 minutes - otherwise you go into deep sleep and it's much more difficult to wake out of that.

If I'm really tired and need to be alert I'll take one or two power naps one after another - and set an alarm for 25 minutes to wake up (and then do the same process again). This works really well - I've gone from being exhausted at the end of a working week to feeling fresh and able to do a 4 hour night time drive.

One thing to try is a 'caffeine nap'. Chug a redbull then immediately take a 25 minute power nap. The caffeine takes 20 mins to take effect, so when you wake from the nap, you'll be catapulted into alertness.
 
For me there is no such thing as a power nap as it usually takes me 30 minutes to an hour to fall asleep, even when I'm tired. When I do try to take a nap and manage to actually sleep, I will feel sick upon waking up.
 
I never feel sick, but certainly groggy after napping for a couple of hours. I usually don't nap, however.
 
Not sick, but my head is in a fog and I feel slow for a few hours if I over sleep.


I don't nap much, on average I might nap once a week, if that. But when I do, this is how I feel. I also wake up with heartburn as well. Not sure what that is about. Usually some tums gets rid of it, but I just find it weird that I get heartburn afterwards.
 
If I'm having a nap whilst bathed in sunlight, yeah I do. Otherwise nope! I think it's a heat thing with me.
 
texas naps

im retired now at age 54, i usually take naps daily,some are short and some are 3 or 4 hrs.depending,i wake up feeling awful and it takes awhile to regroup some times it even puts me in a snapish mood,i never feel bad when i wake up in the morning its just when i nap,any suggestion on how to avoid this:eek:
 
I don't take naps, no matter how tired I am, because I always end up feeling worse when I wake up. I just tough it out until bedtime and try to get a good night's sleep.
 
No, I don't. I feel better, refreshed, and ready for what the rest of the day may have to throw at me. It possibly helps that I am something of a night owl, anyway, and a nap arms me for a nocturnal spell of work, if circumstances call for it.

Actually, I'm a big fan of the rejuvenating qualities of a short (or long) nap. However, up until my early twenties, I thought the whole idea inexplicable.

Then, one summer while working abroad in my student days, I had a job which required a 6 a.m. start which was horribly incompatible with the all night partying some of us were prone to in those days.

Afternoon naps became not something inexplicable indulged in by the terminally aged, but an absolute necessity if one was to have a social life and a paying job. Overnight, I became a big believer in the restorative properties of the afternoon, or early evening nap.
 
The sleep research suggests that the length of the nap effects how one feels upon awakening.

Though there are certainly exceptions, but a nap of 20 minutes (30 at the most) is most likely to be refreshing. A long nap, say 45 minutes or more, is more likely to produce grogginess or discomfort upon awakening. Also napping late in the evening can be refreshing, but conceivably interfere with sleep onset at one's usual sleep time.

These are, of course, general statements, and may not apply to any particular individual. They do seem to hold up pretty well in the research.
