Trekkers arriving at higher altitude commonly experience poor quality sleep. Sleep at a higher altitude can become fitful and difficult. High altitude can have many effects on the body. Oxygen which is at 20.8% (approx.) at sea level dwindles to 13% at an altitude of 3,600 meters. The lack of oxygen causes the preliminary disturbance in the sleep pattern. It causes rapid breathing to maintain proper oxygen flow. The rapid intake of oxygen also causes a faster rate of Carbon dioxide release. The carbon dioxide sensors in the body try to control the rapid release by slowing the rate of exhaling of CO2. Due to these adjustments in fast and slow breathing, a trekker experiences a disturbed sleep pattern (Sleep Apnea).
