The sleep cycle refers to the progression through different stages of sleep that typically occurs multiple times during a night. It includes non-REM (Rapid Eye Movement) sleep, which is further divided into stages 1, 2, and 3, followed by REM sleep. Each complete cycle lasts about 90 to 120 minutes and repeats approximately four to six times per night. These cycles are essential for restorative sleep, impacting memory, mood, and overall health.
REM or Rapid Eye Movement. You sleep in cycles, moving from lighter to deeper sleep and back. A sleep cycle lasts about 90 minutes, with REM occurring toward the end of each cycle. The REM stage gets a little longer in each cycle; you may only dream for a few seconds in the first sleep cycle, and for a large percentage of the last cycle of the night.
Deep sleep typically occurs about 30 minutes to an hour after falling asleep, during the first sleep cycle of the night. The duration and frequency of deep sleep can vary based on individual factors such as age, overall health, and sleep patterns, but it generally lasts longer in the earlier cycles of sleep. Generally, adults spend about 13-23% of their total sleep time in deep sleep.
Stage 2 of the sleep cycle usually lasts around 10 to 25 minutes and tends to make up around 45-55% of total sleep time. It is characterized by a decrease in body temperature and heart rate, as well as the presence of sleep spindles and K-complexes on EEG readings.
Depends on the age of the person, for adults it's approximately seven to eight hours per night. However you do have cycles during your sleep, these are "REM" and "non REM" sleep.

A micro sleep typically lasts for a few seconds to a few minutes. It is a brief period of unintentional sleep that can occur when a person is sleep deprived or fatigued.
