Sleep

== =__**Sleep**__= Researchers say that we spend about one-third of our lives sleeping.We spend about 8 hours/day, 56 hours/week, 240 hours/month and 2,920 hours/year sleeping. Evidence is building that sleep may play a crucial role in strengthening memories.When we sleep,the brain is very active**.** Sleep follows a regular cycle each night. Experts on the topic tell us how the EGG pattern works, the EEG pattern changes in a predictable way several times during a single period of sleep. While we are asleep, our brains are on a bit of a "roller-coaster" through different stages of sleep. As we drift off to sleep, we first enter stage 1 sleep. After a few minutes, the EEG changes to stage 2 sleep, then stage 3 sleep, then stage 4 sleep. Then it's back up again: stage 3, stage 2, then a period of REM sleep...then it's back down again, and back up again, and down again...you get the picture. As shown in the figure below, in an 8 hour period of sleep, the brain cycles through these stages about 4-5 times.Our dreams combine verbal, visual and emotional stimuli into a sometimes broken, nonsensical but often entertaining story line.We can sometimes even solve problems in our sleep.Dream experts say that manypeople disagree on exactly what the purpose of our dreams might be. Are they strictly random brain impulses, or are our brains actually working through issues from our daily life while we sleep -- as a sort of coping mechanism? Should we even bother to interpret our dreams? Many say yes, that we have a great deal to learn from our dreams. Vibrations of soft tissues located at the back of our throats cause the noisy, annoying sounds of snoring. The palate, uvula and tonsils are the tissue structures that flap against each other when someone has too much tissue at the back of their mouth or when an obstruction is blocking the air passageway to the back of the throat. 20% of the population experiences snoring problems while sleeping. Males and obese people have more problems with snoring. Snoring tends to be louder when a person sleeps on their back. There are more than 300 devices registered in the U.S. Patent and Trademark Office to help cure snoring.
