REM
Sleep apnea is a serious sleep disorder that occurs when a person's cycle of breathing is interrupted during sleep. Untreated sleep apnea can disrupt the sleep cycle hundreds of times a night.

The sleep cycle means how human sleeps and at what time. For example if everyday I wake up at 7 in the morning, then take a nap at 12 at noon and go to sleep at 11 at night that is called sleep cycle.
The two-process model of sleep helps us understand the biological mechanisms that regulate the sleep-wake cycle. It suggests that two processes, one related to the body's internal clock and the other to the accumulation of sleep pressure, work together to control our sleep patterns. This model is important because it explains how our bodies naturally regulate when we feel sleepy and when we feel awake, helping us maintain a healthy sleep-wake cycle.
They sleep until you open the app again. ;)
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.

The longest REM cycle occurs in the early morning hours. This is why it's easier to lucid dream on weekends, longer hours of sleep in the morning.
