Different phases and cycles of sleep

When you go to sleep, you traverse through various stages before falling into a deep sleep. In the beginning, you enter into a light sleep mode from where you can quickly wake up. This stage is short-lived, though. In the next level, the brain waves gradually become slack. It is also a stage of light sleep. After that, in levels 3 and 4, your sleep gets deeper. It’s not easy to wake up from this condition. According to experts, the human body and immunity system heal and grow during the third and fourth phases of sleep.

Following these comes the final stage in the cycle, called Rapid Eye Movement (REM). It is this stage where you see dreams, and your brain is active. It processes all the details and creates lasting memories.

The duration of the cycle can be anywhere from 90 to 110 minutes. The length of the REM cycle keeps extending as you continue to sleep.
