Altitude sickness is one of the pathological effect of high altitude on humans, caused by acute exposure to low partial pressure of oxygen at high altitude. It occurs above 2,400 meters (8,000 feet) commonly. It presents as a collection of nonspecific symptoms, acquired at high altitude or in low air pressure, resembling a case of “flu, carbon monoxide poisoning, or a hangover”. However, most people can ascend to 2,400 meters (8,000 ft) without difficulty.

In short we can say it as:- Air is always “thinner” at high altitudes. When you go too high and too fast, your body cannot get as much oxygen as it needed. This causes the headache and other symptoms of altitude sickness on us.But As your body gets used to the altitude, the symptoms goes away.

Primary symptoms of AMS:

The best way to avoid altitude sicknes are as follows: 

  • Stop and rest where you are.
  • Do not go any higher for at least 24 to 48 hours.
