This from Protective CO2 and aging:aquaman said:Where is this from?visionofstrength said:Peat's said he's even willing to accept mild respiratory acidosis (pH < 7.35) if it means you can get your pCO2 up.
Ray Peat said:Ordinarily, carbon dioxide and bicarbonate are thought of only in relation to the regulation of pH, and only in a very general way. Because of the importance of keeping the pH of the blood within a narrow range, carbon dioxide is commonly thought of as a toxin, because an excess can cause unconsciousness and acidosis. But increasing carbon dioxide doesn't necessarily cause acidosis, and acidosis caused by carbon dioxide isn't as harmful as lactic acidosis.
He's also quoted as saying this, I think in an interview [or if he did say this, it could be from one of his books or newsletters not published on the web, i.e., this quote is not on raypeat.com]:
I seem to remember the quote might be from this interview, but it's a great interview for many reasons:Ray Peat said:I think of high altitude as analogous to the protected gestational state. (Both progesterone and carbon dioxide are increased in people adapted to high altitude.) Respiratory acidosis, meaning the retention of carbon dioxide, is very protective, and is an outstanding feature of life in the uterus. Even at the time that an embryo is implanting in the uterus, adequate carbon dioxide is crucial. Many of the mysteries of embryology and developmental biology have been explained by the presence of a high level of carbon dioxide during gestation. For example, an injury to the fetus heals without scarring, that is, with complete regeneration instead of the formation of a sort of collagenous plug. Over the last fifty years, several people have discovered that simply enclosing a wound (for example an amputated finger tip) in an air-tight compartment allows remarkably complete regeneration, even in adults, who supposedly have lost the power of regeneration. (Exposure of tissues to air causes them to lose carbon dioxide.)
