Is there any way that I can reduce the amount of sleep I need voluntarily? Right now, I need a lot of sleep (ten hours or more) and I would like to reduce this so that I can sleep healthily for eight hours a night. Is this possible, given the way that my body works? I have heard that it is, that I can "train" my body to require less sleep. It certainly isn't healthy to sleep fewer than eight hours if my body needs ten, of course. And I'm sure that some people are forced to sleep for six or fewer hours a night for years! Do their bodies just adapt?

Some roommates of mine and I have been thinking about sleeping lately.

Usually we're all told to get eight to nine hours of sleep, and a lot of the time we do! The problem is, once in a while, when there's an essay to write or exam to study for, I or my friends may end up having no choice but to be up until 6 in the morning. No one's really explained what the best thing is to do if you have to be up.

What would you suggest? Should we eat? Take a quick nap before class, sleep during the afternoon or wait until evening? Any suggestions you have would be great.

1) What are the long-term effects of sleep deprivation?

2) Me and a few friends are planning on doing a fundraiser where we stay awake for five days straight. At first it was a great idea, but I started thinking about if there might be some serious damage to our bodies for staying awake that long. Will there be any long-term or short-term damage for staying awake for five days? If so, is it safer to stay awake for three or four days?

And how long can the body really go without sleep?

I am a very light sleeper so I began wearing ear plugs to be able to sleep uninterruptedly. I moved into a quieter neighborhood now and thought that I would be able to sleep without them but it turns out that my boyfriend is a snorer and so I have to keep wearing them. I know that ears clean themselves out at night but because I'm wearing the ear plugs I have a lot of wax build-up. How can I clean my ears? And also, do you think that prolonged use of ear plugs can cause some kind of damage?
