“Most people, including many doctors, still think that everyone’s normal temperature is 98.6 F. In fact what’s normal depends on the person and the situation, and it’s rarely as high as 98.6 F,” said Julie Parsonnet, MD, professor of medicine and of epidemiology and population health as well as the George DeForest Barnett Professor in Medicine. She is the senior author of the study that was published Sept. 5 in JAMA Internal Medicine.

Time to redefine normal body temperature?
New data suggest it may be time for a change.

"During the nearly 160 years covered by the analysis, the average oral temperature gradually fell by more than one degree. As a result, the new normal seems closer to 97.5˚ F."

@Insomniac This is truly a shame. Make people warm again!

Thank you for sharing this impressive marker of doom and gloom.
Overall metabolic decline across the board.
Is 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?It boggles my mind how much heat is still being irradiated by healthy infants and children. They are like little power plants in comparison to adult life.
Reminds me of another publication on breathing frequency I had seen recently. Nowadays the PR reference range starts at >12/minute and lower PRs are simply being ignored and deemed impossible. Whereas back 100 years ago or so the average was somewhere between 6-10/minute (vaguely remembered).
I reckon PR and temperature are probably not directly related with each other, though, i.e., low PR can present with low temps, too. -
@CrumblingCookie My pleasure

The explanation that keeps coming up from mainstream sources is that dropping temps is from a cleaner environment and lower infection burden.

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.
