Can you go straight into REM sleep?
Most cases of narcolepsy are caused by low levels of hypocretin, a neurotransmitter that is connected to wakefulness. That might explain why, when people with narcolepsy fall asleep, they go straight into REM sleep.
How many times should you hit REM sleep?
Every stage lasts about 90 minutes or more, but non-REM sleep often takes up the first 70-75\% of your total sleep time, and your body won’t skip over these stages to reach a REM state first — each cycle usually repeats up to three or four times a night as well.
Does brain activity increase during REM sleep?
During REM sleep, brain metabolism increases dramatically to near-waking levels. The combination of atonia, active cerebral metabolism, and an EEG pattern that at times resembles alert wakefulness has led to the characterization of REM sleep as a metabolically awake brain in a paralyzed body.
What happens if you wake up during the REM stage of sleep?
During this stage, your brain produces delta waves, very slow brain waves. It’s hard for someone to wake you up during this stage. You have no eye movement or muscle activity. If you’re woken up, you may feel groggy and disoriented for a few minutes.

What causes lots of REM sleep?
Getting an unusually large amount of REM sleep in a given night is often an indication that you are sleep deprived. Your body routinely gets most of its REM sleep later in the night, during the final hours that you are asleep.
What happens to the brain during REM sleep?
During REM sleep, brain activity increases, voluntary muscles are inhibited, and rapid eye movements and dreams occur (McCarley et al., 1995). The next section will go into more detail on REM sleep as well as the characteristics of the specific stages of non-REM sleep.
What is the difference between NREM and REM sleep?
NREM stage 2 is followed by NREM stage 3. NREM stage 2 is then repeated. Finally, you are in REM sleep. Once REM sleep is over, the body usually returns to NREM stage 2 before beginning the cycle all over again. Time spent in each stage changes throughout the night as the cycle repeats (about four to five times total). 9
How many times does the cycle of REM sleep occur each night?
The cycle is repeated three to four times each night. An adult spends more time in NREM sleep than in REM sleep. An infant usually spends about half of the sleeping time in NREM and half in REM stages. Top of the page
What happens in Stage 2 of non-REM sleep?
Stage two is characterized by further slowing of both the heartbeat and breathing, and the brain begins to produce bursts of rapid, rhythmic brain wave activity known as sleep spindles. Formerly known as stages 3 and 4, stage 3 (N3) is the final stage of non-REM sleep.
