Sleep apnea意思是

"Sleep apnea" is a medical term that refers to a sleep disorder characterized by breathing pauses during sleep. The word "apnea" comes from the Greek words "a" (without) and "pnoia" (breath), meaning "without breath." People with sleep apnea experience one or more episodes of stopped breathing during their sleep, which can last from a few seconds to minutes. These episodes can occur many times throughout the night and can disrupt sleep, leading to daytime drowsiness, fatigue, and other health problems. There are two main types of sleep apnea: obstructive sleep apnea (OSA) and central sleep apnea (CSA). OSA is the more common type and is caused by a physical blockage of the airway, while CSA is caused by a problem with the brain's ability to control the breathing muscles.
