Vaccinations
Do you any plans to review, analyze and evaluate the history of vaccinations and the recent and ongoing controversies around the COVID virus, its many vaccinations and the Yale University initiative to develop an airborne vaccination that can be given to people entirely without their knowledge, consent or need?
Does hyperventilation (deliberate or not) actually deliver more oxygen to your brain and other tissues?
Hi! In the episode 'AMA #10: Benefits of Nature & “Grounding," Hearing Loss Research & Avoiding Altitude Sickness', at ’45:13’ you say ”you’re delivering more oxygen to your brain and other tissues”. Could you explain this as it made me confused? I’ve learned that hyperventilation, deliberate or not, actually reduces oxygen delivery to your brain and tissues. I think there is a study showing a 41% reduction of oxygen to the brain after 1 minute of hyperventilation. Please let me know if I have got this wrong and help me get it right. From my understanding when you hyperventilate you decrease your levels of CO2 (which helps to release oxygen from hemoglobin to be able to be delivered from the blood and into the brain and tissues - The Bohr effect). The other thing why I thought hyperventilation reduced oxygenation to the brain and tissue was because a decrease in CO2 makes the smooth muscle around the blood vessels contract and reduces the delivery of blood to the brain and tissues. I have read that hyperventilation increases oxygen dissolved into the blood by ~2%, but as the blood flow is reduced, plus the Bohr effect, this increase doesn’t affect the oxygenation in the end. Thank you for a great podcast!
POTS -How to quickly manage episodes
I would like to know if your breathing exercises or recommendations to slow the heart rate would work with POTS episode. When I feel one coming on, I fear I will hyperventilate and make it worse. Will breathing g slower and deeper work physiologically with POTS?
