Resting Body Temperature and Long-Term Survival in Older Adults at a Mental Health Center: Cross-Sectional and Longitudinal Data
Emerging evidence suggests that higher basal body temperature is associated with reduced survival and accelerated aging in non-obese older adults.
One for the CR people. But the data might just confirm that temperature drops as you get older. Perhaps not having too much insulation is also important. I’ll bet people who exercise are better at temperature regulation.

I suspect this is a good line of research. Perhaps we need to again spend more time climbing those snow-covered mountains Joe.
People are working on new drugs to do this, and rapamycin seems to do this:

Agreed. Those were the days. I’ll add that I have found that my regular sauna use (and perhaps my cold showers) has trained my body to be better at temperature regulation. For the first couple months my body temperature would be elevated for long enough to walk outside with no shirt in 5-25F temperature for 15 minutes (2 loops around the track). Now my body temperature doesn’t feel elevated after 5 minutes (I don’t feel hot by the time I get to my locker). Something is improving.
I believe homeostatic range expansion is an important anti-aging intervention.

You’ve made my day!!
I was not dealt a hand with good longevity genes in other areas (heart etc), but it appears this one thing might be a winner!
Whenever I do take my temp, I assumed something was wrong with me because I’m never as high as 98.6… hallelujah!

Lower body temperature has been found to be beneficial for longevity in mice. Transgenic mice with a reduced core body temperature have an increased life span - PubMed
A slightly low body temperature is likely also beneficial for humans. Lowering temperature is pretty much the only thing that slows down almost all the stochastic reactions that contribute to aging, including reactions like glycation of the extracellular matrix.

My usual body temperature is 97.5 - 97.7. Sometimes it’s even closer to 97. It’s within normal range, but I’m always cold and usually put on more layers than most ppl.

Ha, I always suspected that. I tend be to cold all the time, had a whole thyroid panel done multiple times. I think the years of endurance makes the body process extremely efficient, especially when done in the hot deserts of Arizona.
Physically it makes sense that higher temperatures are associated with higher entropy.
This is the main reason why I couldn’t continue IF, I would get insanely cold - to the point I could put layer after layer and still be cold… while sweating. Weird physiological reaction.
