In order to have a great night’s sleep, your body needs to experience four stages of sleep:
- Stage 1 – your eyes will be closed. This may last five -10 minutes.
- Stage 2 – your heart rate slows and your body temperature decreases. This is your body preparing to enter deep sleep.
- Stage 3 and 4 – You are the deep sleep stages. This is when REM sleep occurs.
Your body generally needs to wake up at the end of these four stages to feel the most well rested.
