Understood emo kid	Average 7-9 hours. Everyone's different. It doesn't matter. Sleep as much as you can-but don't sleep too much. All is good in moderation. If you have trouble sleeping, knowing how much others sleep on average won't help.

TRANSLOPEDIA	What Happens During Sleep? You don't notice it, of course, but while you're asleep, your brain is still active. As people sleep, their brains pass through five stages of sleep. Together, these stages - which doctors call 1, 2, 3, 4, and REM (rapid eye movement) sleep - make up a sleep cycle. One complete sleep cycle lasts about 90 to 100 minutes. So during an average night's sleep, a person will experience about four or five cycles of sleep. Stages 1 and 2 are periods of light sleep from which a person can easily be awakened. During these stages, eye movements slow down and eventually stop, heart and breathing rates slow down, and body temperature decreases. Stages 3 and 4 are deep sleep stages. It's more difficult to awaken someone during these stages, and when awakened, a person will often feel groggy and disoriented for a few minutes. Stages 3 and 4 are the most refreshing of the sleep stages - it is this type of sleep that we crave when we are very tired. The final stage of the sleep cycle is known as REM sleep because of the rapid eye movements that occur during this stage. During REM sleep, other physical changes take place - breathing becomes rapid, the heart beats faster, and the limb muscles don't move. This is the stage of sleep when a person has the most vivid dreams. Is very important to sleep, stadies shows that is better 9.25 Hours Here are some things that may help you to sleep better: Set a regular bedtime. Going to bed at the same time each night signals to your body that it's time to sleep. Waking up at the same time every day can also help establish sleep patterns. So try to stick to your sleep schedule even on weekends. Don't go to sleep more than an hour later or wake up more than 2 to 3 hours later than you do during the week. Exercise regularly. Try not to exercise right before bed, though, as it can raise your body temperature and wake you up. Sleep experts believe that exercising 5 or 6 hours before bedtime (in late afternoon) may actually help a person sleep. Avoid stimulants. Don't drink beverages with caffeine, such as soda and coffee, after 4 PM. Nicotine is also a stimulant, so quitting smoking may help you sleep better. And drinking alcohol in the evening can also cause a person to be restless and wake up during the night. Relax your mind. Avoid violent, scary, or action movies or television shows right before bed - anything that might set your mind and heart racing. Reading books with involved or active plots may also keep you from falling or staying asleep. Unwind by keeping the lights low. Light signals the brain that it's time to wake up. Staying away from bright lights (including computer screens!), as well as meditating or listening to soothing music, can help your body relax. Don't nap too much. Naps of more than 30 minutes during the day may keep you from falling asleep later. Avoid all-nighters. Don't wait until the night before a big test to study. Cutting back on sleep the night before a test may mean you perform worse than you would if you'd studied less but got more sleep. Create the right sleeping environment. Studies show that people sleep best in a dark room that is slightly on the cool side. Close your blinds or curtains (and make sure they're heavy enough to block out light) and turn down the thermostat in your room (pile on extra blankets or wear PJs if you're cold). Lots of noise can be a sleep turnoff, too. Wake up with bright light. Bright light in the morning signals to your body that it's time to get going. If you Smoke, stop 3 hours before you go to bed. If you bealive that you don't get enough sleep. YOU MUST talk to your Dr. Good luck!!!
