What is sleep? If we go by the scientific definition, it can be defined as the natural and periodic state of rest during which consciousness is suspended. It is the time when our body and mind relax and get ready for next day’s work. Scientists have since long tried to decipher the mysteries behind this natural process. What happens after we fall asleep? Do we see dreams all the while? Different theories have come up in response to these questions.
Sleep can be categorised into different categories- deep slumber, light sleep, falling asleep immediately etc.Â Falling asleep constitutes the stage one of falling asleep. The mind starts to relax and a person starts drifting away into the mysterious world of sleep. The breathing becomes slow, heart beat becomes more regular and blood pressure decreases. It is easier to wake up a person during this stage and the person would not feel if he actually fell asleep.
After 15 to 20 minutes of falling asleep, we descend into the stage two of sleep. During this point of time, the brain does not show any change in the brain wave pattern. It is slightly difficult to wake up a person from this stage of sleep. A sound in the close vicinity may wake up a person.
After 30 to 45 minutes of falling asleep, the brain wave pattern changes. At this stage we move into the stage 4 of deep sleep. At this time, it will take a lot of efforts to wake up a person. Only a very loud noise may wake up a person. If woken up from this stage of sleep, a person feels groggy. The metabolic activity of brain decreases during deep sleep.
During the deep sleep our body and mind replenish and rejuvenate. Hypothalamus signals the pituitary gland to increase the secretion of human growth hormone(HGH). HGH is also referred to as ‘fountain of youth’ as it enables to restore the youthful state. It promotes tissue building and growth in children.
During the Rapid Eye Movement(REM) the brain waves shift again and eyes flutter back and forth under closed eyelids. It is during the REM that we dream.
For a healthy body and mind, it is essential to take 6 to 8 hours of sleep everyday. Sleep disorders are caused by the lack of proper sleep. It can be avoided by maintaining a proper sleep cycle.
When an individual has a sleeping disorder such as insomnia or sleep apnea, he may be curious to know what a sleep clinic is and what it does. It may be able to help his condition. A breathing device known as a continuous positive airway pressure (CPAP) machine can help people with sleep apnea, but sleep clinics don’t utilize many more sophisticated machines and equipment than that other than to hook up the patient with many different electrodes and studies them with a type of electrocardiogram (EKG) machine.
What They Do
It’s essential to understand that sleep clinics don’t solve any specific problem. They’re not meant to do that. Their primary purpose is to simply collect all of the symptoms and patterns of a person’s period of nocturnal rest. These patterns and symptoms are then relayed to the physician in charge there and he interprets the results to evaluate and diagnose the underlying reason for nocturnal rest difficulties, whether its insomnia, dysomnia, or even walking during a time at night when a person should be sleeping.
Electrodes are placed on the subject’s eyes, temples, forehead, and top and back of the head, as well as on other parts of the body. They help the staff of highly trained technicians to measure different diagnostic criteria and parameters such as REM or rapid eye movement signs. Most people at these places don’t spend very much time there. Sometimes, people spend just one night, while others might be there for one to two weeks at the longest.
Sleeping is an intricate science in and of itself and its mechanism of action is still not completely understood but at these centers the technicians do their best to record all of the pertinent characteristics of nocturnal sleeping patterns so that they can most fully determine all of the many possible variations in sleeping that any specific patient manifests. Trying to sleep in a foreign environment is not easy. But some patients do it much easier than others. Many though find it impossible to drift off especially if they’re not given any aids or pills to help drift off for the night.
This can be problematic, but the subject eventually does indeed drift off so he can be thoroughly studied and evaluated for information to be prepared and given to the physician who runs the center. Many subjects don’t enjoy their stay there but since they have such sleep problems they truly do need to be there to be fully evaluated in order to be helped for the long haul. Being at one of these clinics under evaluations only benefits the patient in both the short and long term, and while there are few physicians who actually specialize in sleep disorders, the ones in charge at these clinics can definitely help the individual out once he leaves the facilities.
Sleep Doctors Can Help You Determine What is Disrupting Your Sleep
When you are suffering from a sleep disorder, it can be hard to know where to turn and what type of help you need. These conditions are very hard to detect and sometimes require specific treatments to be resolved. Sleep problems can be very infrequent or occur nightly. The symptoms may not be so obvious because they happen while you are asleep. Common things to look for include being very tired during the day, mood changes, decreased health, and the inability to perform as you normally would. You could be having trouble getting to sleep every night or waking up frequently. These are all signs of a problem that needs to be evaluated and fixed.
Not all sleep problems are due to a sleep disorder. The normal routine you perform before bed or other things you do during the day can affect sleep as well. Drinking a lot of caffeine or consuming alcohol before bed can prevent sleep and cause frequent awakenings. Eating specific foods, your sleep environment, and bed time habits all determine how well you sleep. Before assuming you have a disorder, take a thorough look at what you consume and do each day. Incorporate exercise get rid of additional energy. Make sure your bed room is comfortable and promotes healthy sleep. It needs to have comfortable bedding, a good temperature, and as little light and noise as possible. Change your nightly routine so you have time to relax and unwind from the day. These little adjustments can make a big difference.
Medical conditions and medications may be altering your sleep. See your regular doctor and discuss what is going on and the changes you have made to try to remedy the issue. They will perform tests to see if a medical issue is preventing you from getting the amount of rest you need. Check the medications you are taking to see if sleeplessness is a common side effect. Then discuss this with your doctor to see if another medication can be taken or something else can be done to reduce how the medication affects your sleep. Your regular doctor may be able to help you fix the situation. If they cannot then they may recommend that you see a specialist or be evaluated by a sleep facility.
Sleep doctors are available all over the country. Sleep medicine itself is an emerging field that is more common due to the increased concern over disorders and how they affect overall health. What do sleep doctors do? They often use specialized facilities to perform tests while you sleep. These facilities have controlled environments that have all the comfort of a bed room. Monitors are attached to various parts of the body to record brain activity and other responses during each phase of sleep. A technician does the monitoring and takes note of any visual symptoms that occur during the testing. The doctor takes a look at the test results and determines if a disorder exists and possible treatments. They go over the results and explain each treatment option giving you the opportunity to ask questions and choose what remedy works best for your situation.
A specialist can help you determine if a sleep disorder is causing your sleep problems. These doctors are familiar with the various types of disorders and their most common symptoms.
Obstructive sleep apnea, or OSA, is a sleeping disorder characterized by recurrent episodes of abnormal pauses in breathing or significant decrease in airflow caused by collapse of the upper airway in the respiratory system. By definition, apnea episodes last about an average of ten seconds.
Apnea may occur hundreds of times in a single night, one to two times a minute in severe obstructive sleep apnea victims, and is often accompanied by wide swing s in heart rate, an abrupt decrease in saturation of oxygen, and brief electroencephalogram arousals associated with stertorous breathing sounds as a burst of air is exhaled when the airway reopens.
Three major symptoms of sleep apnea include snoring, drowsiness, and other significant abnormalities during sleep apnea episodes. These signs help clinicians and dentists in assessing patients for obstructive sleep apnea. It has proven to be valuable in educating people to be sensitive in the detection of the sleeping disorder. It is also helpful if someone close to the victim can have knowledge about obstructive sleep apnea because, oftentimes, the sleeper is unaware that he is actually suffering from obstructive sleep apnea. In fact, he can regard himself as a good sleeper just because he can sleep anytime, anywhere. Sleepiness is one of the most morbid symptoms of sleep apnea, owing to the accidents that can result because of it.
According to a dentist Memphis Tennessee has, obstructive sleep apnea is a very important diagnosis for dentists and physicians to consider because of its strong relevance with the most critical medical conditions, including hypertension, cardiovascular illnesses, coronary artery disease, insulin-resistant diabetes, depression, and sleepiness-related accidents.
Obstructive sleep apnea is an increasingly rampant condition in both children and adults. Based on the statistics by a licensed dentist Memphis TN has, approximately 24% of men and 9% of women have obstructive sleep apnea. These figures do not include excessive daytime sleepiness victims. The prevalence in children is less certain but an increasingly large portion of the adolescent population is suspected of having sleep apnea. Most of these adolescents are suffering from obesity and have similar symptoms to their adult counterparts.
Obstructive sleep apnea should be diagnosed and treated immediately, as cases of sleep apnea Memphis has is quite alarming. Sleep apnea can be quickly reversed with the proper titration of continuous positive airway pressure devices provided by dentists specializing in sleep apnea cases. Continuous positive airway pressure devices are the standard treatment options for obstructive sleep apnea.

As with most sleep disorders your doctor will probably order a sleep study or polysomnogram. This usually entails one or two overnight stays in a hospital, sleep study centre or clinic. The first visit will be to gather data, the second if necessary to have a trial run on the CPAP machine or whatever other remedy the doctor will recommend.
What is a polysomnogram? A polysomnogram (or sleep study) is a multi-component test that records specific bodily activities while you sleep. It is carried out to determine the cause of sleep problems, such as insomnia, narcolepsy, insomnia, restless legs syndrome and shift work sleep disorder. It is generally non-invasive and despite being hooked up to various electrodes I didnâÂÂt find it any more difficult than usual to sleep. For a test in a sleep centre or hospital, you will be in a private bedroom. Technicians attach the surface electrodes to you before you sleep. The readings are recorded throughout the night. The data is analyzed and interpreted by the specialist to determine whether you have a sleep disorder such as sleep apnea and if so to what degree. Sometimes EEGÂ (electroencephalogram) may be done to record brain activity, or an EMG (electromyogram) to record muscle activityÂ such as restless leg syndrome or the presence of REM sleep, or an EOG (electro-oculogram) to record eye movements to determine the different sleep stages, or an (ECG (electrocardiogram) to record heart rate and rhythm, or a nasal airflow sensor to record air intake andÂ a snore microphone to record snoring rate and severity.Â The captured data will show how long you slept, the depth and duration of your sleep and how often you were awake or disturbed. This data is usually expressed in events per hour, or events per minute.
Sleep studies also can be done with portable equipment you use at home.
Other Sleep Studies. Â Multiple sleep latency test (MSLT). This test measures how long it takes you to fall asleep, and also determines whether you enter REM sleep (deep restful sleep). Maintenance of wakefulness test (MWT). This test measures whether you can stay awake during a time when you are normally awake. If the doctor suspects a problem with your body’s internal clock (circadian rhythm), you may have a test called actigraphy. For this test, you wear a device on your wrist that resembles a watch. The device measures your movement during sleep and waking periods. It helps your doctor learn what times during the day you are active and when you are not.
These studies are an important tool to diagnose and treat sleep disorders.
What Time Should You Sleep
Is there a best time to sleep? There is a saying that sleeping early and waking up early is good for your health. How true is that? Is it alright to sleep late and wake up late?
You actually have an amazing biological clock ticking inside your body. It is very precise. It helps to regulate your various body functions including your sleeping time.
From 11pm to 3am, most of your blood circulation concentrates in your liver. Your liver gets larger when filled with more blood. This is an important time when your body undergoes detoxification process. Your liver neutralizes and breaks down body toxins accumulated throughout the day.
However if you don’t sleep at this time, your liver cannot carry out this detoxification process smoothly.
If you sleep at 11pm, you have full 4 hours to detoxify your body. If you sleep at 12am, you have 3 hours. If you sleep at 1am, you have 2 hours. And if you sleep at 2am, you only have 1 hour to detoxify.
What if you sleep after 3am? Unfortunately, you won’t have any time to actually detoxify your body. If you continue with this sleeping pattern, these toxins will accumulate in your body over time. You know what happens next.
What if you sleep late and wake up late?
Have you tried going to bed very late at night? Did you realize you feel very tired the next day no matter how much you sleep?
Sleeping late and waking up late is indeed very bad for your health. Besides not having enough time to detoxify your body, you will miss out other important body functions too.
From 3am to 5am, most blood circulation concentrates in your lung. What should you do at this moment? Well, you should exercise and breathe in fresh air. Take in good energy into your body, preferably in a garden. At this time, the air is very fresh with lots of beneficial negative ions.
From 5am to 7am, most blood circulation concentrates in your large intestine. What should you do at this moment? You should poop! Pass out all unwanted poop from your large intestine. Prepare your body to absorb more nutrients throughout the day.
From 7am to 9am, most blood circulation concentrates in your stomach. What should you do at this moment? Have your breakfast! This is your most important meal in a day. Make sure you have all the required nutrients from your breakfast. Not having breakfast causes lots of health problems for you in the future.
That’s the way to start your day
There you are… the most ideal way to start your day. After fully detoxifying your blood during your sleep, you wake up fresh to inhale beneficial energy. Then you pass out unwanted poop from your large intestine. After that, you take in balanced nutrients to prepare your body for a new day.
No wonder people living in villages or farms is healthier. They sleep early and wake up early. They follow their natural biological clock.
Living in city, we have more difficulty in following this sleeping schedule. We have good lightning, TV and internet to delay our precious sleeping time.
Following your natural timetable
Once I know the importance of our biological clock, I try my best to follow it. If I wake up early, I usually start my day on the computer. But when I see the clock shows 7am, I know it’s the best time for breakfast. So I’ll try to have my breakfast before 9am for best absorption.
What if you’re offered a night shift job? I recommend you to reject it even the salary is higher. For long term, you may need to spend more money for your health problems.
What if you have assignment to do until late at night? Well, why not sleep early and wake up earlier to do it? Just shift your work time from late night to early morning. You get the same time. But your body will appreciate it.
With this, try to follow this timing as close as possible. Make it your daily routine. I’m sure you will feel fresher and more energetic all day long.
