At high altitudes oxygen levels are low, the pressure of air is one third of that at sea level, wind speed is very high, and temperature drops very rapidly. These factors make breathing and movement difficult, easily lead to frostbite and make a person get tired easily.

High altitude sickness is a life-threatening condition characterised by thickening of blood and death of brain cells caused due to oxygen deprivation.

As very little oxygen reaches the brain, climbers find that their minds become dull and they revert to the mental capacity of a child.
