Answer:
True
Explanation:
It is true that one type of personal health monitor measures the amount of time that you spend on REM sleep. REM (rapid eye movement) sleep is a phase of sleep in which rapid and random movement of the eyes occurs. This is also the stage of sleep in which a person dreams more vividly.
