If human beings are exposed to normobaric hypoxia with an inhaled oxygen of 10.5% for one hour, how long does the effect of hypoxia persist after cessation of hypoxia exposure?
Dear Sir, I had worked on a similar project with Yoga based breath holding applications. What we found was that the effect varies with exposure to the environment.
To be more precise, we observed that in experienced practitioners who did breath holding for longer time, the body was adapting to it in a much better way. But whereas in case of novices the effects were more pronounced sympathetic activation.
However, we have not seen the duration that it persists.
As indicated above there are a number of hormones and inflammatory markers that will remain elevated for a few hours after exposure. Feelings of headache, lethargy, light-headedness and dizziness can occur after exposure. We now prevent our participants from driving home immediately after, due to reports of dizziness and 'faintness' after exposures. However, all physiological variables monitored (SpO2, HR, VE) will appear as normal almost immediately after exiting the chamber.
