Altitude: Oxygen deprivation

Written by on July 20, 2020

When a person travels to a high altitude, the air pressure is a lot lower (barometric pressure).  This means that there is less oxygen present. High altitude is considered 8,000 feet and above. There is about 25% fewer oxygen molecules in the air at this level. The body has to find ways to compensate for this lack of air. Some people are particularly sensitive to higher elevation and may experience “altitude sickness”. For those who live at a higher altitude, their bodies have adjusted. For others who travel to a place with higher altitude, the body will need to figure out how to adjust.

Symptoms include headache, dizziness, shortness of breath,
loss of appetite, fatigue, and trouble sleeping. These usually occur within 12
to 24 hours of being at the higher elevation.

There are 3 types of altitude sickness:

  1. Acute mountain sickness (AMS): A person might
    feel like they have a hangover, are dizzy, feel nauseous, or have a headache.
  2. High altitude pulmonary edema (HAPE): The lungs
    can start to build up with fluid. A person might have trouble walking, their chest
    could feel tight, and they could have a severe headache.
  3. Edema (HACE): Fluid can start to fill up in the
    brain. This can be life threatening. A person might feel very confused, not be
    able to walk, could go into a coma, and have shortness of breath even at rest.

Anyone is at risk for altitude sickness, even an Olympic
athlete. Exercising at higher elevation puts a person at increased risk. There
are many variables to consider such as how high the elevation is, how quickly
the person entered this environment, or even where you sleep. Younger people
are more at risk for getting sick.

If any of these symptoms arise, the best immediate solution
is to go down to a lower elevation. The best way to prevent altitude sickness
is by acclimatization. The body can slowly get used to higher elevations. Many
athletes do this if they know they will be competing at a higher elevation. The
lungs can build up and learn to take deeper breaths to allow for more red blood
cells to supply oxygen. Consuming extra carbohydrates and drinking plenty of
water is highly recommended. The body is resilient, but it needs to learn as
well. Gradually approach higher elevations and the body will come prepared for
you.
