The primary sleep apnea cause occurs when you are unable to get air into your lungs while asleep and this may be because of your throat staying open making you unable to breathe, or because of a temporary collapsing of your throat which makes you wake up at night because of having become breathless.

Lifestyle

Lifestyle is one of the factors that could increase the chance of developing sleep apnea. Nowadays, so many people like to drink alcohol. Alcohol affects the part of the brain that controls breathing. This may relax the throat muscles and narrow the airway. As the results, not enough air flows into your lungs.

Smoking and taking some medicines that are taken for conditions such as allergies, insomnia, anxiety and depression also cause the same effects. As could as possible, avoid it so the possibility of airway closure during the night could be reduced.

Obesity (Over Weight)

When you have too much body fat, it can broaden to all parts of your body. Thus, the soft tissue within your mouth as well as at the rear of your throat will soon get some unwanted fatty deposits. The extra soft fat tissue causes pressure on the airway, increasing the chance that the airway passage will collapse. If this happens to you, use a sleep apnea dental device in case of mild sleep apnea will enable you to breathe continuously and thus ensure adequate and restful sleep at night.

Shape of Head and Neck

The shape of head and neck also has contribution to sleep apnea. Often, it may be shaped in a manner that causes a smaller airway size in the mouth and throat area. Continuous Positive Airway Pressure (CPAP) treatment is the best way to treat this and other sleep apnea causes.

Please, keep in mind that untreated sleep apnea can impact to your health overall.
