“Preliminary research evidence indicates that even a small elevation of the ambient pressure might be lifesaving”.
A reduction in brain oxygen levels (brain hypoxia) may help to explain early neurological symptoms of COVID-19 (i.e, headaches, fatigue, impaired consciousness, including respiratory distress), which can be seen in a significant proportion of more severe cases. Other neurological symptoms typically observed in those suffering from long-COVID may be attributed to the imbalance of the autonomic nervous system (ANS) and dysautonomia. It has been reported that around 67% of individuals with long COVID are developing dysautonomia. Keep in mind, the ANS plays a critical role in regulating immune function, inflammation, coagulation pathways, fatigue, exercise intolerance, cognition, along with many more factors relating to physiological functioning.
Hyperbaric oxygen therapy (HBOT) is a very simple, safe, and non-invasive intervention that helps to relieve tissue and brain hypoxia, particularly at lower pressures! This procedure can also stimulate the vagus nerve (an integral part of the ANS) to help restore viral-related dysfunction of the ANS and this may explain long-COVID patients reporting relief from fatigue, cognitive impairment, weakness, headache and dizziness among many others after completing a course of hyperbaric oxygen therapy.
