Adenosine rises and wanes in your brain over a 24-hour period to help you fall asleep and stay asleep until morning. Your brain purges stored adenosine as you sleep to reset the sleep homeostat.
Second Law:
To manage your sleep-wake cycle, your circadian rhythm the inner body cycle that dictates your energy peaks and troughs throughout a roughly 24-hour cycle should function harmoniously with sleep homeostasis. Its ultimate purpose is to assist you in getting the normal, healthful sleep your body requires. Your circadian rhythm not only guides the daily swings in your energy levels, but it also determines your ideal sleep and wake hours to give you the best chance of achieving your sleep requirements.

First Stage (Non Rapid Eye Movement):
This initial stage, which comprises of light sleep, indicates the transition between awake and sleep. Muscles relax, and your heart rate, breathing, and eye movements, as well as your brain waves, which are more active when you are awake, begin to calm down.

- No eye movements
- The body’s temperature falls
Third Stage (Non Rapid Eye Movement Stage 1 + Stage 2):
This stage is critical in helping you feel refreshed and awake the next day. The heart rate, breathing rate, and brain wave activity all fall to their lowest levels, and the muscles are as relaxed as they can be. This stage will last longer at first and then shorten throughout the night.

- There are no eye movements
- Immune system enhancement
Fourth Stage (Rapid Eye Movement):
