Eric's Review of Caldera Sauna
Valarie's Review of Caldera Sauna
The Hidden Shift That Shapes Your Longevity
Genes account for only ~20% of your longevity. The rest comes down to a few key biological systems that keep you strong, energized, and resilient
Over time, these systems gradually lose efficiency…
Muscles, organs, and skin get less oxygen; fatigue sets in faster
Tissues recover more slowly; soreness lasts longer
Harder to bounce back; stress lingers
Waste builds up; toxins stay longer in your system
Energy dips; recovery takes longer; weight and strength harder to maintain
