Stage three lasts a few minutes thought the electroencephalographic shows high-voltages, and slower wave activities. But the last stage of non-rapid eye movement lasting the longest of the four stages, from twenty to forty minutes. Usually, REM sleep happens 90 minutes after you fall asleep, after the four stages. The first period of REM usually lasts 10 minutes. Each of your later REM stages gets longer and can go on for as long as an hour. At this point of the night, your heart rate and breathing become heavier. "This phase of REM is defined by the presence of desynchronized (low-voltage, mixed-frequency) brain wave activity, muscle atonia, and bursts of rapid eye movements", (Colten 34-36). Unlike the other phases, your muscles become loose and your brain is more active giving gateways to dreaming and is affiliated with REM sleep. Adults who spend 20% or less in REM sleep, babies can spend up to 50% of their sleep. Body system changes that occur during sleep. Through the stages of sleep-specific bodily functions are changed through NREM sleep and REM sleep such as brain activity, heart rate, blood pressure, nerve activity, airway resistance, and body
