M., Sleep Disorders and Sleep Deprivation: An Unmet Public Health Problem, Sleep Physiology. Rapid Eye Movement(REM) has been correlated with dreams and sleep physiology. It has been tracked by brain waves and muscle movements. Non-Rem(NREM) sleep is the first phase which occurs for 1-7 minutes and the easiest to be interfered with. The brain begins firing betawaves every 15-30 seconds. After a while the person becomes asleep and breathing regularly between 6-8 seconds in the second stage. The heart rate begins to slow down and so does the blood pressure. In the third stage there are more thetawaves along with sleep spindles(sigma waves) and k-waves. Most of the noise are lock out and the heart rate and blood pressure are decreasing. In the fourth phase there are thetawaves in the appearance of delta waves firing at 1-5 seconds. The last and final stage, the person is in their deepest sleep and it is very difficult to wake up. The heart rate and blood pressure are at their lowest and the delta wave are blasting every 1-5 seconds. The source is creditable but it is a second hand research because they use different experiments from past authors. This is going to be use in a research paper because it give plenty of information about sleep and how they believe it has been caused. Dr. Harvey R Colten was a pediatric
