Beginning in 2018 for Stage 3 of Meaningful Use (optional in 2017), VDH will accept registrations from only EPs that practice in an urgent care setting. All other types of EPs may claim an exclusion for syndromic surveillance in Stage 3 of Meaningful Use.
The Takeaway. 1  Although there is some genetic variation, most adults need between 7.5 to 8.5 hours of sleep per 24-hour period to function optimally. 2  You can find your optimal sleep time if you set aside several days (perhaps during a vacation) to allow yourself to sleep as long as possible. Once you know how much sleep you need, it's important to allot that amount of time in your daily schedule for sleep.
REM sleep occurs at intervals of one to two hours, and is variable in length. REM sleep is characterized by irregular breathing and heart rate, and involuntary muscle jerks. Most adults need around eight hours of sleep on a regular schedule to function well, although some require less, and others more. (It has been said that men need an hour less sleep than women.) Children, particularly teenagers, often need nine or ten hours for optimal functioning.
