If you’re having a tough time getting to slumber knowing how you slumber or knowing the mechanics behind what makes a healthy night’s sleep could help you resolve the issue of what is keeping you awake. Slumber is not as easily understandable as you believe because of the various levels of rest. There are umpteen rest processes that take place once your eyes shut and you fall asleep that contributes to how deeply or how softly you will sleep.
The first stage of sleep is called stage one which is characterized by drowsiness and this is where your muscles relax, you start to feel tired, and you can no longer keep your eyes open. This stage usually lasts only a few minutes usually between five and ten. The very next stage of sleep is considered a very light “stage two” and in this stage both breathing rate plus temperature drop. Your pulse will also slow down as well during this stage.
Stages three and four are easily determined to be deep sleep and are where it should be hard to wake up. You might feel a bit dopey and unable to come awake promptly but this important sleep stage allows your brain to rest while the circulatory system slows, after which it is redirected to the body in order to help restore the body. There is also an increase in immune functions during these important stages of rest.
REM sleep is stage five and is known as the dream portion of the REM sleep cycle. Moving in and out of the REM cycle occurs often so you may find yourself having several dreams during your period of REM. This intricate stage of sleeping is determined by some physical breathing conditions both shallow and deep. There may also be a rise in heart rate and blood pressure.
This particular portion of the entire sleep cycle is designed to assist in the processing of emotions and to help relieve stress with each of the sleep cycles giving the person a truly good night’s sleep. People who sleep lightly are usually in stage two and rarely go into three and four where the best benefits of sleep reside. Those who can’t wake up so easily likely are stuck in the deeper parts of sleep and awake suddenly rather than come awake through the various stages of sleep.
Sleep can be put off kilter based on the amount of each cycle you got the night before so if you spend a long time in deep sleep the next night you may spend more time in REM or light sleep. Your body adjusts over time and you spend the same about of time on average in each part of sleep, hopefully resulting in good sleep patterns. That’s why it is more true that you cannot make up on sleep but you can always get caught up on rest.
