Is it good for a period of 1-2 hours? Explain.
Apparently, the oxygen level is low in your TV room, too :tongue2: .Yes. That's what they invented TV's for, isn't it?
Two things knock me out almost immediately: TV's and riding an airplane (on an airplane, the oxygen level is knocked down a little making it real easy to fall asleep).
Oh, I thought it was Gagging Diversion.I think js's answer is relevant to the question. If you actually have a biology question try that forum. This is General Discussion, also known as GD
A 2 hour nap in class is a lot of time, too. You could fall asleep in the middle of American History and wake up with a whole different set of people in the classroom - speaking French, no less!I said "depends on when" because 1 - 2 hours is a lot of time to just sleep away. There's a lot more you could be doing. So what I do is take naps during class.
That's the kind of answer I was looking for. The main disadvantage of naps seem to be disturbing sleep.I try to avoid taking naps, they mess with my sleep cycle.
John Medina even argues that we are biologically hardwired to nap for 20-30 minutes, which is why many people get that afternoon sleepiness, even after a good night's sleep, and that the north-american lifestyle of sleeping once a day is not natural."When I was at NASA we gave the pilots a planned nap in the cockpit," says Rosekind, who is a board member of the National Sleep Foundation. "While two pilots flew the plane, the third would have 40 minutes to nap. We found they would sleep for 26 minutes, which boosted their performance by 34% and their alertness by 54%."
3 to 4 hours isn't a nap, for some that's a full night's sleep! I got through grad school by taking naps between about a half hour and hour during lunch time (and just ate quickly while heading back to the lab). That way I could get up for the early morning experiment before the 8 AM lecture, get through my morning classes, get a little sleep, then continue on in the lab until 9 or 10 PM (or all night when needed).No, if the nap is to do any good it has to be at least 3 hours long. Thats why military pilots on long range flights are allowed to take 'power naps' 3-4 hours in length. Less than that, and you lose coordination and dont wake up 'refreshed' if your pulling long hours.
That's the whole point...I take them when I know my sleep cycle will be disrupted anyway. It's also why I answered "it depends." If you're only going to delay doing something that could be done by the time the nap time would be done and disrupt your sleep so you're in the same pattern the next day, it's not worth it. But, if you know you have to be up all night anyway, and that night might get a bit shorter if you aren't making mistakes because you're exhausted, then a nap is just the thing.I try to avoid taking naps, they mess with my sleep cycle.
I was on the ball for the question you actually asked. Now you're changing your question if you say the nap needs to be at a time when you don't have other commitments that are affected by taking it or not taking it. What would be the point of that? If you have nothing else to do later, or are able to get regular sleep at regular times, there's no need for a nap.That's the kind of answer I was looking for. The main disadvantage of naps seem to be disturbing sleep.
When I say refer to taking a nap, I always mean at an appropriate time when other committments are not affected. So the only trade off in that case would be not being able to sleep as well in the night. Hence Moonbear, your answer wasn't quiet on ball.
Is that why I do a long session of head nodding forward, chin going lax, and head snapping back up, repeatedly, for the first while when I get on planes? I can be fully rested and put me on a plane, and I'm all undignified head movements and facial expressions.(on an airplane, the oxygen level is knocked down a little making it real easy to fall asleep).
