The Brain and Sleep" If you attach an electroencephalograph to a person's head, you can record the person's brainwave activity. An awake and relaxed person generates alpha waves, which are consistent oscillations at about 10 cycles per second. An alert person generates beta waves, which are about twice as fast. During sleep, two slower patterns called theta waves and delta waves take over. Theta waves have oscillations in the range of 3.5 to 7 cycles per second, and delta waves have oscillations of less than 3.5 cycles per second. As a person falls asleep and sleep deepens, the brainwave patterns slow down. The slower the brainwave patterns, the deeper the sleep -- a person deep in delta wave sleep is hardest to wake up.
At several points during the night, something unexpected happens -- rapid eye movement (REM) sleep occurs. REM sleep is when you dream. You must have both REM and NREM sleep to get a good night's sleep. Medicine can hamper your ability to get a good night's sleep. What's the difference between jail and prison.
