Altitude Sickness
Altitude sickness occurs when there is a lack of oxygen. As altitude increases, the concentration remains the same but the number of oxygen molecules per breath is reduced. Below is a list of frequently asked questions concerning the illness.
At what elevation can altitude sickness
occur at?
It can occur if you ascend rapidly to 6000 feet and can become more severe
if you travel above 8000 feet without acclimatizing.
What is acclimatization?
This is when your body adapts to the decrease in oxygen molecules
at a specific altitude.
Are there different types of altitude sickness?
Yes, there are three types. There is acute mountain sickness (AMS),
high altitude cerebral edema (HACE), and high altitude pulmonary edema
(HAPE).
What does “climb high sleep low” mean?
This is a common term used amongst climbers. It means that you can
climb more than 1000 feet in a day, as long as you come back down to sleep
at a lower altitude.
What are some symptoms associated with altitude sickness?
The general symptoms resemble that of a hangover; headache, fatigue, loss
of appetite, nausea, and occasionally vomiting.
What are some factors that will increase my risk of getting altitude sickness?
Factors that will make an individual more susceptible to the illness include:
- fast ascent
- altitudes above 6000 feet
- previous history of AMS
- strenuous activities at high altitudes
- obesity
- female
- lack of acclimatization
