Fact about this altitude

What changes at high altitude?

The environment is completely different at high altitude compared to that at sea level - the air is thinner and temperatures are usually much colder. In order to survive at high altitude, it is necessary to acclimatise(acclimate). This means that changes occur in the body so that it can cope with the shortage of oxygen.
