Symptoms Of Severe Sleep Apnea
If you’re having problems sleeping it is critical that comprehending sleep mechanics and what makes up a healthy night of rest may be instrumental in understanding why you have a rest condition. Comprehending sleep is not so simple because you aren’t of necessity up or asleep. The’re a number of things that occur as soon as you start to drift off to sleep that determines how restful that slumber is to you.
The first stage of sleep is called stage one which is characterized by drowsiness as your feel yourself let go, your muscles fall into a limp state, and your eyes will drift closed on their own. This stage usually lasts only a few minutes somewhere around ten full minutes. The next stage is light stage often called stage two and in this stage both breathing rate plus temperature drop. The heart rate may also slow down as well during this part of sleep.
Both stage three and stage four of the sleep cycles are classified as deep sleep and are where you may have difficulty waking up. You will possibly feel very dazed and incoherent but this stage allows the brain to rest and as a result blood flow actually decreases, at which point it begins to rejuvenate the body. It is important to note that there is a increased level of immune work that occurs during these two important stages of rest.
The most fascinating stage is called stage five or REM sleep and is generally considered the dreaming period of the sleep cycle. Drifting in and out of stage five happens often so you may find yourself having several dreams within the 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 good for helping your mind process heavy emotions, stress reduction and 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 probably hanging around too long in deep sleep and awake suddenly rather than come awake through the various stages of sleep.
Sleep stages can become random based upon the time you have spent in each sleep stage through the previous week, so if you spend too much time in a heavy sleep one night you might become trapped in a light sleep the next evening. Ultimately however it balances out and you’ll likely spend equal amounts of time in all of the sleep stages. This is one of the reasons why it is stated that it is impossible to get caught up on sleep but you can catch up on rest.
