When the body is exposed to increase Altitudes, the pressure in the surrounding atmosphere decreases. The number of people travelling to the high altitude regions, especially South America, Nepal, and India, has risen enormously in the past 10 years, and many have experienced struggle or health issues because of the difficulty in adjusting to the changes in pressure. Many are under the impression that oxygen levels decrease at higher altitudes, but actually, the level is consistent at all altitudes that humans would venture to on earth, but rather the ability for our lungs to transfer the oxygen from our lungs is decreased at lower pressures. This is where Schizandra has been seen to once again act as a savior in stressful conditions. Schizandra has been seen to increase the body’s ability to optimize the uptake of oxygen from the lungs to the blood. Having this pathway opened up was seen to counteract the change in pressure experienced by the lungs at high altitudes, allowing the body to experience the results of more oxygen intake, which is greater endurance and stamina.

Similarly, in areas of high air pressure, the body’s ability to uptake oxygen is also decreased when the body is under physical activity, as in the case for swimmers or scuba divers. The body responds to the pressure change with a decrease in power requirements, taking less oxygen, but the body actually feels a lowered aerobic activity. It was seen that after Schizandra administration, a similar result was experienced as in lower pressure environments. The body and lungs were able to absorb more oxygen allowing the athletes to experience normalized endurance.
