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.
Clinically, it has been indicated that usually within a week
of being exposed to the high altitudes, the person will
experience insomnia where they will be able to sleep but the
sleep will be interrupted consistently due to the inability to
catch their breath. They may feel like they are suffocating or
choking. There may also be other symptoms as mentioned above
that can accompany the altitude insomnia.
Altitude insomnia occurs in about 25% of people who rise
about 2000 miles above sea level. Clinically, altitude insomnia
has a few other names such as acute mountain sickness, Acosta's
disease, Alpine sickness, and hypobaropathie. The primary cause
of this is exposure to low air pressure which is what happens
to people at high altitudes. Now because the aircrafts of today
are modernized, the cabins are pressurized which therefore does
not affect travelers on airplanes.
Normally it is the symptoms that are associated with the
altitude that trigger the insomnia. Those who climb mountains,
pilots, or flight crews follow what they consider to be a
Golden Rule, "Fly high and sleep low." While that might not
make much sense to the average Joe, to them it signifies a way
to expose and re expose themselves to repeated altitude little
by little to avoid these symptoms. They ascend gradually,
however this is not possible with flight crews. Many claim that
fast ascension is not the issue at all but experts do agree
that there is much about this in particular disorder that is
not fully understood yet. There has been a strong link though
that has indicated that when there is a rapid dissension that
the symptoms disappear very quickly.
There are drugs that can also help to prevent altitude
insomnia; Diamox and Sumatriptan are both prescribed with the
prevention of altitude sickness in mind, therefore eliminating
any altitude insomnia. Self help measures include drinking
plenty of water and cocoa leaves have also been known to help
altitude sickness as well. Although altitude insomnia is one of
many symptoms that occur with extreme heights, it is important
to remember that this is a lung complication where the lings
are affected by the extreme altitude.
Recently a new drug came out to help people with this
condition. Acetazolamide will be able to help many people that
are subjected to altitude related illnesses. What researchers
found was that this drug reduced pressure within the lungs by
relaxing muscles that line the lungs' capillaries. This reduces
fluid in the lungs and increases oxygenation.
