Human Variation & Race
1. High-altitude conditions are difficult on the human body by definition because air pressure is lower and less oxygen is taken into the body with each breath. The condition is known as "hypoxia," and it results in destabilization of internal body conditions, or homeostasis. Hypoxia damages the brain, muscles, and organs, which need oxygen to work properly. If one has not sufficient of it, people develop such as dizziness, drowsiness, shortness of breath, or confusion. Worse still are high-altitude pulmonary edema (lavage in the lung) or high-altitude cerebral edema (swelling of the brain), which, if not treated, kill. They show themselves in the way that the body is working to deliver enough oxygen to keep processes at a standard rate, and it creates a fatal imbalance within the internal processes of the body. 2. One of the very first things that your body is going to do when you are traveling to a high altitude is breathe more rapidly. This is a quick adjustment and...
