As a subject matter expert in the field of psychology and physiology, I can provide some insights into the relationship between anxiety and oxygen levels. Anxiety itself does not directly cause a lack of oxygen. However, the physiological response to anxiety can lead to behaviors or conditions that might indirectly affect oxygen intake. For example, during a severe anxiety attack, a person might experience hyperventilation, which is rapid and shallow breathing. Hyperventilation can lead to hypoventilation (inadequate intake of oxygen) because the person is not taking in enough deep breaths to fully oxygenate their blood. This can cause hypoxia, a state of low oxygen levels in the body, which can in turn exacerbate feelings of anxiety and lead to a cycle where anxiety and hypoxia feed off each other. It's important to note that while hypoxia can be a result of severe anxiety and hyperventilation, anxiety itself is not a cause of hypoxia. Instead, it's the body's response to anxiety that can potentially lead to this condition. Mild forms of hypoxia might not be lethal but can still impair cognitive function and emotional state. In summary, while anxiety does not directly cause a lack of oxygen, the body's response to anxiety can lead to behaviors that might indirectly affect oxygen intake and result in hypoxia. read more >>

Hypoxia, or a low blood oxygen level, if severe enough, is lethal. But milder forms of hypoxia can impair thinking, alter levels of consciousness, cause depression and stir up anxiety.read more >>
