Sleep Apnea Cause
If you’re having a hard time getting to sleep comprehending the mechanism behind sleeping and how it recharges you might help you solve the issue of what is keeping you up. Sleep is not as simple as you believe because you are either awake, asleep, or somewhere in between. The’re a number of things that occur once your head rests on the pillow and you close your eyes 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 is the fastest developing phase, usually between five and ten. Stage two of sleep is a very faint sleep and at this point your respiratory system and body temperature fall considerably. Your heart rate should also lag during this part of sleep.
Stages three and four are easily considered “deep sleep” and are certainly 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 work that occurs during these two vital stages of your good night’s rest.
The most fascinating stage is called stage five or REM sleep and is generally considered the dreaming period of the sleep cycle. Entering and exiting this cycle happens many times during sleep so there may be several minutes or hours during your period of REM. This intricate stage of sleeping is determined by a number of physical responses where you may experience rapid breathing that is of the shallow sort, deep or even irregular. You could also show signs of your heart quickening as a rise in blood pressure.
This important time in the sleep stage is vital to helping you process certain emotions for stress reduction and providing a benefit to the person sleeping. Those who tend to sleep lighter than others are stuck in the early sleep stages and hardly ever make it to phases three and four where they need to be in order to obtain the most rest possible. For those who have a hard time arousing from sleep probably hanging around too long in deep sleep and rise quickly upon waking rather than running through each stage.
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 you will likely sleep lightly the following evening. It really balances out over time and you will spend about the same average over time in all of the sleep stages. This is one of the reasons why it is stated that you cannot make up on sleep but you can always make up on lost rest.
