POLYSOMONGRAM 😴 STUDY: If you’re having sleep troubles, chances are you may get a polysomnogram. This overnight study uses electrodes to monitor brain waves, eye and muscle movements and heart rate, and respiratory sensors to monitor breathing and oxygen levels. This picture of your sleep can help uncover many diagnoses! A sleep technician shows us what to expect. #SleepHealth #Sleep #Sleepmedicine #SleepStudy #worldsleepday
