ALL ABOUT ALTITUDE

u No one can really predict who will suffer from altitude sickness which is caused by a decreased level of oxygen in the blood. While it’s normal to breathe faster and deeper and experience mild headaches and shortness of breath, severe altitude sickness with prolonged coughing and vomiting can be extremely serious, requiring possible hospitalisation. u Asthmatics sometimes fare better at high altitude, especially those who suffer from allergens rather than the effects of exercise. u Trekkers in Peru chew cocoa leaves which help combat altitude sickness.
