Altitude Insomnia
Insomnia can show its ugly little face in many different ways. Pilots, flight attendants, and even military trainees can suffer from this rare form of insomnia. This occurs when there is ascension to altitudes greater than about two miles up. In addition to the insomnia itself, altitude insomnia also includes fatigue, headache, and loss of appetite. One thing to keep in mind is that altitude is not always a factor that is related to flying in an airplane because altitude insomnia is also common among mountain climbers too.
