If you keep waking up in the middle of the night without any explanation, the body may be trying to tell you some of these things.

We go through many phases during the night which affect how deeply we sleep. We start with the phase where we are just-asleep and pass on to non REM (Rapid Eye Movement) to a deep sleep, REM. Experts say that REM sleep happens every 90-120 minutes. For a lot of us, we keep waking up at the beginning of the night which is when the sleep is shallow.
