Saunas
Infrared, traditional Finnish, or hybrid — sauna therapy has some of the strongest longevity research behind any biohacking modality. But not all home saunas are created equal.
The sauna research is exceptional: regular use correlates with reduced cardiovascular mortality, improved heat shock protein production, and better insulin sensitivity. But the home sauna market ranges from truly therapeutic units to glorified heated closets. We evaluate infrared saunas on actual heater output, EMF levels at seated position, build quality, and whether the temperature ranges are sufficient for genuine heat stress protocols.
