Everest Base Camp Trek Acclimatization

Generally, Acclimatization means the process by which the body adopts a new environment and weather. Normally, two kinds of altitude zones are found in the Everest Base Camp Trek. One is from 2500m to 3500 m called a high altitude zone and next is from 3500 m to 5500 m called a very high altitude zone. There exists extreme danger zone, death zone in the Everest base camp trek too, but you don’t need to reach higher than 6000m. so, you will be facing these two zones.

Trekkers react differently to a different zone. The reaction starts above 2,400 m. Passing this altitude, people start feeling a change in weather and whole the environment. As a result of this, altitude sickness starts. So, acclimatization at this time is important during the Everest Base Camp trek.

You can notice the Sherpa people residing in the Everest region don’t need the process of acclimatization because they are familiar with the environment. But it’s a completely new environment and hence this is the reason why acclimatization days are kept in our Everest Base Camp trek Itinerary.
