Evolutionary psychology is a discipline that studies how universal patterns of behavior and cognitive processes have evolved over time as a result of natural selection. Jim Horne discusses the latest research on sleep, dreaming and sleep deprivation. During this time, the body works to gently lower the heart rate, temperature, and breathing rate.   It most often occurs when insufficient hours of sleep are obtained to meet your individual sleep needs. Adults usually have about 8 hours of sleep per day. Start studying Psychology: Sleep.

The way sleep is structured (the amount of time in the several sleep-phases, etc.) Criteria for determining REM sleep include low muscle tone and rapid eye it protects- as our ancestors hunted by day, they knew to sleep in the safety of a cave and not become the hunted by night.
