The first stage is when your eyes are closed, this stage may last up to 10 minutes. The second stage is when your muscles start to relax, your body temperature starts to drop, and your heart rate slows. Stage three and four are all deep sleep, with four being stronger, this stage is also known as slow-wave or delta sleep. Rem sleep occurs 90 minutes after you fall asleep. The first period of REM sleep usually lasts 10 minutes and the last one up to an hour. When you are in the REM stages, your body will have increased brain activity, eye movement, muscle relaxation, and accelerated respiration. Dreams are also very common in REM sleep, and lots of people tend to have them every few nights.
