If you are having real trouble with sleeping or you awaken feeling regularly exhausted, then you are probably not getting the right amount quality sleep. So, for us to understand the right kind of quality sleep, it might be smart to analyze what happens when we are "in sleep." You see, when we are in sleep we go through different sleep ways known as sleep cycle stages, and it is these stages that hold the key to higher quality sleep if you want to judge sleep quality score.
During the length of our sleeping period we successfully go through 5 sleep cycle stages: 1, 2, 3, 4 and REM. These stages are recurring several times throughout your sleep
This is the least heavy level of sleep usually when you are just moving off. As you go in and out of sleep the sight edge and muscle activity reduces right down. In this level, you can be awoken easily.
In level 2 the eye motions prevent and your respiration decreases right down. The brainwave also reduces but can be distributed with jolts of fast mind activity.
Awfully slow brain wave called “Delta waves" come into play but fast mind activity is still present but much more uncommon. The sleeper’s respiration now gets to its the best possible level.
The mental abilities are still generating delta wave, but no more has the fast mind activity that the previous stages have.
This is known as fast eye movement or REM sleep. This is the best level of your sleep cycle because this is when all the game happens. Your respiration instantly becomes faster although superficial. Brain activity improves to a state similar to that of being conscious. Your blood level increases a little bit, and your pulse rate improves. It is at this point when we start to desire.
Stages one and two are known as the less heavy sleep stages, and stages 3 and four are known as strong sleep, and as we go through finished sleep cycle stages, we experience less of the R.E.M stages previously in our sleep pattern but have more length of strong sleep.
The first thing to remember is that it is the "deep sleep stages" that are most valuable to us as this is where the body re-energizes and recuperates. So, if we spend most of our sleeping time gradually 1 and two then no matter how much sleep we have, we will awaken feeling exhausted and fatigued! So, the main point here is that it is all about the type of sleep you have not the amount.
