“Nasty chapped lips was always a problem at the end of several night shifts atop the very high altitude summit of Mauna Kea.” NightLipsAltitudeMaunaKeaNastySummitShiftsAtopChapped Author:Steven Magee
“The Mauna Kea night shift was an 18 hour night in wintertime at the 13,796 feet summit (before sunset to after sunrise) with insufficient time for adequate sleep before the next night shift. Night shift was between 5 and 8 nights long and we slept at 9,200 feet. We sat at a desk staring at four large computer monitors and a large cathode ray tube television. I would also use my Wi-Fi laptop computer. I would have extreme fatigue by the end of every night shift and have chapped lips which I now associate with exposure to the artificial light from the computer screens. A good day of sleep between shifts was rare and starting the next shift fatigued was normal.” LightNightTimeSleepTelevisionComputerLipsMaunaKeaArtificialDayAdequateFatigueSummitInsufficientRareShiftWintertimeExtremeWifiCrtScreenFatiguedMonitorDeskChapped Author:Steven Magee
