Can a healthy person use an oxygen generator to inhale oxygen?

It is acceptable for healthy individuals to use an oxygen generator to inhale oxygen. The detailed explanation is as follows:

An oxygen generator is a machine that produces oxygen by highly compressing air and then performing gas-liquid separation at a specific temperature, ultimately separating oxygen from nitrogen. Oxygen generators can supply oxygen to the body. Healthy individuals may experience hypoxia after intense physical exercise, when in high-altitude environments, or during late pregnancy. In such cases, using an oxygen generator can help improve oxygen levels, and appropriate oxygen inhalation may accelerate metabolism. However, frequent use of oxygen generators is not recommended, as prolonged inhalation of high-concentration oxygen may lead to oxygen toxicity, which is harmful to health.

Oxygen plays a vital role in the body and is essential for sustaining life. During respiration, oxygen is inhaled and carbon dioxide is exhaled. Once inside the body, red blood cells carry oxygen and deliver it to various organs. If the body suffers from hypoxia, doctors generally recommend oxygen therapy to ensure adequate oxygen supply to tissues and organs, thereby supporting their normal function.
