What is the typical sleep pattern?

The typical sleep pattern for adults consists of several cycles of non-REM and REM sleep, lasting about 90 minutes each. Most adults require 7 to 9 hours of sleep per night, experiencing light sleep, deep sleep, and REM sleep throughout the night. Sleep patterns may vary based on individual needs, age, and lifestyle factors, but a consistent sleep schedule is important for overall health. Generally, a person cycles through these stages multiple times, with REM sleep becoming longer in the latter part of the night.
