If you're going to attack the peaks you could suffer due to lack of oxygen. Here are our tips for preventing the effects caused by lack of oxygen and thus avoiding "mountain sickness"
The latter is caused by the available amount of oxygen in the air decreasing and the effect this has on your body. To overcome this lack of oxygen the body must increase the amount of red blood cells in the blood which improves the circulation of oxygen in the body. The first few days at high altitude often result in hyperventilation, headaches and difficulties with the slightest exertion.
It is important to spend time acclimatising. In a few days the body will start producing additional blood cells and it will regain its vitality.
If the symptoms persist it is better to descend to a more comfortable altitude.
