Original Text

Fortunately, AMS only happens when we ascend too fast, because our bodies have numerous ways of adapting to high altitudes. Within minutes or even seconds of reaching altitudes of 1,500 meters, carotid chemoreceptors in your neck sense your blood’s low oxygen pressure. This triggers a response that increases the rate and depth of your breathing to counteract the lack of oxygen. Your heart rate also increases and your heart contracts more tightly to pump additional blood with each beat, quickly moving oxygenated blood around your body.
