Sleep apnea can take a serious toll on general well-being and contributes to health conditions known to worsen COVID-19 outcomes. Despite these findings, scant research has been conducted linking sleep apnea directly to COVID-19 outcomes. There are, however, notable connections showing greater COVID morbidity and mortality among patients with obesity and hypertension, two conditions extremely common to sleep apnea patients. What little research has been conducted lends support to sleep apnea as a significant factor in how well one fares when infected with the CCP virus. Three newer studies use valid retrospective designs to measure available research data. These studies help us understand the impact of this pervasive sleep disorder that goes by the names of obstructive sleep apnea (OSA) or sleep-disordered breathing (SDB). Harvard researchers examined a group of 443 people with sleep apnea who contracted COVID-19 (the CCP virus) and compared them to a control group of who …
