Preparing For Low Oxygen Levels At High Altitude Regions And Avoiding Altitude Sickness

Every year, millions of people travel from sea-level to the high-altitude Rocky Mountain region for vacation, skiing and many other outdoor adventures . However, many of those same people will also experience shortness of breath, tiredness and even altitude sickness because their body isn't used to the change in altitude and lack of oxygen in the air. If their body isn't acclimated, their first few days at high-altitude can be miserable.

While the percentage of oxygen in the air is the same at high altitudes, the air is thinner and there are fewer oxygen molecules present. This can make people feel like they’re not breathing in as much air if they’re not used to spending much time at these elevations.  The good news is, supplemental oxygen can help with altitude acclimation!


We want to explain how to recognize the symptoms of altitude sickness and what you can do to treat and prevent it.

  • Why does altitude sickness happen? When you go to higher altitudes, there is less oxygen for your body, lungs and blood cells to create energy. The faster you climb to higher altitudes, the more likely you will experience altitude sickness.
  • There are several symptoms of altitude sickness, which can range from mild to more severe symptoms which could require medical treatment.
  • The ways to treat mild symptoms of altitude sickness include moving to lower altitude levels, rest and pain relievers. Using supplemental oxygen can also help mild symptoms.
  • The best ways to prevent altitude sickness are to acclimate your body with altitude changes by ascending slowly, stay hydrated and use supplemental oxygen while you ascend.

Why Altitude Sickness Happens

Altitude sickness typically occurs at altitudes over 6,000 feet. The higher you go, the more air pressure drops and there is less oxygen for your body. Simply put, the symptoms of altitude sickness are your body reacting to this lack of oxygen. Altitude sickness also happens if you ascend to higher altitudes too quickly without allowing your body time to acclimate to the altitude changes. It can also occur if you exercise too much (or exert your body) before visiting higher altitudes. Genetics may also increase the risk, including high altitude pulmonary edema (HAPE).

The Symptoms Of Altitude Sickness

There are two types of altitude sickness: mild and severe. Acute Mountain Sickness (AMS) are the mild symptoms which include headaches, shortness of breath, nausea, dizziness, fatigue and muscle aches. High Altitude Cerebral Edema (HACE) and High Altitude Pulmonary Edema (HAPE) result in more severe symptoms. HACE usually develops after mild forms of AMS and can include trouble walking, worsening headaches and vomiting and confusion. HAPE can result in a buildup of fluid in the lungs that can also be very dangerous. It can also occur WITHOUT the signs or symptoms from AMS or HACE. Symptoms from HAPE can include chest tightness, extreme fatigue, inability to catch your breath even when resting, coughing and fever.

Treatment Of Altitude Sickness

The general rule is to stop ascending to higher altitudes if you experience mild symptoms. You can also treat the mild forms with rest, pain relievers and supplemental oxygen. If you experience the more severe symptoms like HACE or HAPE, it is important to descend to lower levels as soon as possible or seek medical treatment.

Prevention Of Altitude Sickness

The easiest way to prevent altitude sickness is by allowing your body to acclimate to the changes in pressure and altitude by ascending gradually. Going slow allows your lungs to acclimate and your blood cells to carry more oxygen to your organs and tissues. Some basic guidelines are to begin your journey at 5,000-8,000 feet and go no more than 1,000 feet per day. Also, stay hydrated with lots of water and avoid alcohol, tobacco and sleeping pills. If you experience mild symptoms of altitude sickness and follow these guidelines, your symptoms should go away within 24 hours.
