So it seems that both very cold and very hot are good for cancer prevention/delay.

Cold influences the glucose uptake while hot influences the immune system and probaly also promote ROS which normal cells can fight off better then cancer.

Metformin + low carb + sauna + cold room seem like great combination.

You'd think there would be a lower rate of cancer in places like Finland then, since they really enjoy their saunas and have relatively colder weather.

It may be cold in those places but why do you assume body temperature is any different there? Humans are good at regulating that, with layering and building heat.

Finns truly have lower body temperatures. 35.3°C right now.

According to american internets I am suffering from constant "hypothermia".

Also I am obviously sufferring from "bradycardia", it is not normal that 70-year old has resting pulse 45.

Not knowing your own personal health no one can say, but it's common for older people with heart issues to have a slower heart rate, so you may be fit as a horse, or you could be having heart issues. If that's the case low temperature has been linked to poor outcomes with heart failure. But only your GP can decide. It just doesn't feel like the slam dunk proof of better health you're saying it is.

This condition been the same for 50 years. I am worried when it changes.

I am pretty sure this is somekind of hereditary trait for Tundra dwellers. If I dont sweat, mosquitoes do not bother me. Also all ticks drop off or just die.

> Also all ticks drop off or just die.

Ok, now I'm definitely worried about your blood.

Achually there was one successful tick-bite. It was July 1957. It managed to suck some blood, but removed itself rightaway when mother Noko burned it with cigarette.

Ah, and it told the others.

I'm half worried and half envious.

That's interesting. I have a very low resting heart-rate and lower than normal body temperature as well. (Also from a northern area).

same. grew up in northern canada and have always had a low body temperature with a resting heart rate of ~47.

Source on that lower body temperature? I live in Finland and am regularly low 36 high 35. My partner is high 36 and Finnish. I can’t lie near them without feeling overwhelmingly hot.

Works for heart disease and likely all cause mortality.

This is almost certainly confounded with other healthful behaviours. Eg people who sauna also eat better, exercise, go to the doctor etc

Pretty well everyone I knew in Finland would sauna, regardless of how they lived the rest of their life, it was just part of the culture.

I would expect a lower rate in Singapore. Sure, it's hot outside 24/7, but people mostly work and live around aircon so strong it's like being inside a refrigerator.

My experience in Singapore is that AC is either not used at home (except during the hottest days) or set very high. When I visited an office there it was set at 27C (82F).
