What is the effect of low oxygen (hypoxia) on the body?

Hypoxia, or low oxygen levels in the body, has a significant impact on physiology and can lead to critical health issues. When the body is deprived of adequate oxygen, it can result in confusion and cognitive impairment as the brain is particularly sensitive to oxygen deprivation. This lack of oxygen affects cellular function, leading to dysfunction of various organs. If hypoxia is severe and prolonged, it can culminate in organ failure due to the inability of cells to carry out essential metabolic processes that require oxygen. Thus, the answer indicating that hypoxia can cause confusion and organ failure if severe accurately reflects the potential dangers associated with insufficient oxygen levels.
