Sleep is required for human life. Both short- and long-term consequences can develop when sleep is restricted or altered by sleep disorders. Sleep affects safety, mood, performance, and health. Rapid Eye Movement (REM) was found in relationship to rest. This disclosure was first noticed and checked with human newborn children. As innovation was applied to quantify brainwaves during rest, it was found that rest shifts or cycles (has engineering). Rest design was first separated into REM and non-REM. Later with more examination, rest design was characterized further by partitioning non-REM rest into stages 1, 2, 3, and 4.
