Sleep apnea, specifically Obstructive Sleep Apnea (OSA), is a sleep disorder characterized by low oxygen levels in the blood, disrupting the individual’s sleep. In OSA, the tongue is pulled toward the back of the throat during sleep, obstructing the upper airway and causing a cessation of airflow. The resulting drop in oxygen levels prompts the individual to partially wake up and clear the airway, restoring normal airflow. However, this recurrent disruption prevents a restful night’s sleep.

Consistently low oxygen levels can have severe consequences for the cardiovascular system. Individuals with sleep apnea may experience difficulties concentrating during the day, constant daytime sleepiness, and even an increased risk of depression.

Upper Airway Resistance Syndrome (UARS) is related to a milder form of airway blockage with similar symptoms. Recognizing and understanding these sleep disorders is crucial for initiating effective treatment. However, diagnosis can be challenging, as many individuals with sleep disorders may be unaware of their condition due to the nature of the disorder occurring during sleep.
