Visitor Information: Effects of High Altitude

As you go to higher altitudes, the barometric pressure decreases, the air is thinner, and less oxygen is available. The air is also dryer and the ultraviolet rays from the sun are stronger. At elevations of 8,000 plus feet, your body responds by breathing faster and more deeply, resulting in shortness of breath, especially on exertion. Many people develop mild symptoms of headache, nausea, trouble sleeping, and unusual tiredness, which is called acute mountain sickness. These symptoms usually go away in a day or two. If symptoms are severe, persist, or worsen, you should consult a doctor.

The effects of high altitude can be decreased by following these recommendations:

• Increase Fluid Intake -- drink two or three times more fluid than usual; water and juices are best.
• Avoid alcohol and minimize caffeine on your day of arrival and one to two days thereafter.
• Decrease salt intake -- salt causes your body to retain fluid, which increases the severity of altitude illness.
• Eat frequent small meals high in carbohydrates, low in fat, and low in protein.
• Moderate physical activity and get plenty of rest.
