Acute Mountain Sickness is an altitude related effect to your body. This happens when your body cannot adapt efficiently to the high altitude. You need not to climb Mount Everest to start feeling the pain from altitude sickness. Whether it is shortness of breath, nausea, or exhaustion, this can totally mess up your trip plan. But with simple precaution you can easily avoid this and adjust yourself to the altitude to have an amazing trip.
What is Acute Mountain Sickness (AMS)
When you travel to altitude higher than 2800 meters / 9200 feet, your body takes in far less oxygen per breath than your minimum requirement which causes altitude sickness. This can happen to any one regardless of your age, gender or fitness level. You might be surprised that this happened to Sir Edmund Hillary.
