Background: Good sleep quality refers to how well a person sleeps which involves
various factors including the depth of sleep, the speed to enter the deep sleep phase
(rapid eye movement/REM), how often a person wakes up during the night, and
how relaxed they feel when they wake up and get the right amount of sleep so that
sleep disorders can be avoided. The 7 aspects of sleep quality indicators include
subjective sleep quality, sleep latency, sleep duration, sleep efficiency, sleep
disturbances, use of sleeping pills and daytime activity dysfunction. Poor sleep
