“In 2017 at the age of 47 I was diagnosed with a rare and disabling sleep disorder called Ideopathic Hypersomnia. I had noticed the onset of the condition during extreme night shift work from 2003 to 2006 on the 13,796 feet very high altitude summit of Mauna Kea. After a few years of doctors visits for insomnia, fatigue, sleepiness and falling asleep at work, it was initially diagnosed as Shift Work Sleep Disorder in 2009 before being correctly diagnosed by a Multiple Sleep Latency Test several years later.” SleepAstronomyOshaAltitudeDisorderMaunaKeaTmtHypersomniaIdeopathic Author:Steven Magee
