--- title: Sleep care | ResMed - KH description: What is sleep apnea? Sleep apnea is a disorder in which the muscles in the throat relax to the point of collapse, restricting airflow. This causes breathing to become shallow and even stop for seconds or minutes at a time, depriving the body and brain of oxygen. The lack of deep sleep can cause significant fatigue and elevate the risk for serious health problems. Most people with sleep apnea are unaware they have it. --- [ Magnet Update ](https://www.resmed.asia/en-kh/mask-magnet-clip-guidelines) [ Philips Recall ](https://www.resmed.com/en-us/other-manufacturer-recall-2021/) [ COVID-19 Update ](https://www.resmed.asia/en-kh/covid19) [ About ResMed ](https://www.resmed.asia/en-kh/about-us) Sleep Care -
