Causes of Sleep Apnea that Prevents You Taking a Sound Sleep at Night

What Causes Obstructive Sleep Apnea?

When your throat back muscles loosen up, it causes obstructive sleep apnea to occur. The throat and tongue side walls, the tonsils, the uvula and the soft palate get support from these muscles.

The relaxation of these muscles causes your airway to narrow down or completed closed while you inhale that causes difficulty in breathing and ultimately may cause to lower down the oxygen level in your blood.

The lowering of oxygen level in your blood temporarily awake you so that you are able to unlock your airway passage. This arousal from sleep is so momentary that you even forget this awakening.

Sounds like gasping, choking and snorting may come out of your mouth and nose. This sequence can continue whole night ranging from 5-30 times or more in an hour. These suspensions of sleep cause unrestful sleep at night and as a result you are likely to feel daytime dizziness.

Obstructive sleep apnea patients are usually not conscious of their sleep disruptions at night and on the contrary they feel like as they took sound sleep the whole night.

What Causes Snoring and Obstructive Sleep Apnea? What is Obstructive Sleep Apnea (OSA)?

What causes central sleep apnea?

At times, when your breathing muscles do not receive signals from brain, a less usual type "central sleep apnea" occurs. During this time, you actually do not strive to breathe at all. Consequently, you may awake due to breathe disruption or find difficulty in sleeping.

While you are not asleep, the muscles of your throat cooperate to maintain your airway passage tough and released that makes it possible for you to breathe without any difficulty. On the contrary, during sleep the muscles of your throat get relaxed and the throat gets contracted.

Generally, this contraction is not the reason that impedes the air flow to your lungs. However, the airway may turn out to be partly or completely choked in case of sleep apnea because:

* The muscles of your tongue and throat loosen up extra than usual.

* The tonsils and tongue are larger than the windpipe opening.

* You are obese. The additional tissues of fat can make the windpipe's wall thicker, thus making it hard to keep it released.

* The bony composition of your neck and head maybe a reason of limited size of airway in the throat and mouth areas.

* The process of growing old maybe limiting the ability of brain to send the signals to the muscles of throat to keep them hard while you sleep. Hence, there is an extra possibility of narrowing or collapsing of the airway.


The level of oxygen will fall down in the blood and a forceful snoring can takes place if the airway is partly or completely choked and sufficient oxygen does not flow in your lungs while you sleep.

The dangerous drop of oxygen level in your blood will activate your brain to disrupt your sleep as it facilitates stiffening of the upper side muscles of the airway and releasing of the windpipe. This creates restarting of the breathing process with a forceful choking or snorting noise.

Hormones of stress may also get released due to regular decrease of oxygen levels in the blood and as a result increase the heart rate and raise the threat of irregular heartbeats, stroke, heart attack and high blood pressure. Your risk of heart failure is also increased by these increased stress hormones.

The unrecovered sleep apnea can also alter the way your body utilizes energy and this altered way of utilizing energy also elevates the threat of diabetes and obesity.
