Patrick: the data on exercise and mortality is unequivocal — moving from the bottom 25% to top 2.5% of VO2 max reduces all-cause mortality by 5x. No drug achieves this effect size.

Sauna use mimics exercise — heat shock proteins and cardiovascular conditioning
Patrick: regular sauna use (4-7x/week, 174°F+) reduces cardiovascular mortality by 50% and Alzheimer's risk by 65%. The mechanism: heat stress triggers heat shock proteins, improves endothelial function, and produces cardiovascular conditioning similar to moderate exercise.Was this useful?
