Obstructive Sleep Apnea occurs when the tongue and soft palate collapse onto the back of the throat during deep sleep and causes a blockage in air flow. When this occurs for a long enough period of time (10 sec or more) it causes the brain to react. The drop in oxygen level signals the brain to wake the individual from deep sleep. This constant awaking also prevents the rest we need to restore/refresh our brain leading to unrefreshed sleep and feeling of constants fatigue.
Snoring is known to be a warning sign of Obstructive Sleep Apnea. It is a partial closing of the airway.
If you are drowsy throughout the day or are told you snore you may be suffering of OSA. Ask your dentist for a sleep Dr. referral to be diagnosed.
