Altitude Physiology

Altitude physiology refers to how the human body responds to changes in altitude, especially at high elevations where oxygen levels are lower. As altitude increases, the air pressure decreases, leading to reduced oxygen availability. The body compensates through processes like increased heart rate and breathing to deliver more oxygen. Over time, it can adapt by producing more red blood cells. However, rapid ascent can cause altitude sickness, with symptoms such as headaches, nausea, and fatigue. Understanding altitude physiology is crucial for mountaineers, travelers, and athletes for safety and optimal performance in high-altitude environments.
