@CrumblingCookie said in Normal body temperature is now 97.9. "it’s rarely as high as 98.6 F":
s it just PUFA? Is it an altered setpoint of carbohydrate/caloric malnutrition? Is it electromagnetic interference of physiological cellular functioning? Is it a (low-key) chronic disease state?
PUFA is one key reason. The more PUFA and the less SFA the fat being used as a substrate in fatty acid metabolism, the more likely the mitochondria is deprived of co-factors it needs to run on sugar-based mitochondrial metabolism.
Sugar metabolism becomes cytosolic and glycolytic, which produces much less energy. More lactic acid is produced and less CO2.
Less energy already makes for lower temperature. But it gets worse when the body has less available CO2. Because enough CO2.is needed in the blood to effect adequate tissue oxygenation of our cells and tissues. Without enough oxygen in the tissues, the body will keep on producing energy inefficiently by producing energy from sugar glycolytically, and become more dependent on fatty acid mitochondrial metabolism, the mitochondrial pathway throttled as it is on oxygen being limited already.
The combined capacity of the mitochondria and the cytoplasm to produce energy will be much less, and this would be reflected in lower temperatures across the board.
Last year my lungs had bronchitis and I was not getting enough oxygen from breathing. At that state, and unaware of the effect of has, I dove in my fishpond to clear some debris from the bottom. I got hypothermia from it. I was shivering a lot, and struggled to come up. My temperature has gone down to 35C in less than a minute.
