Why Sauna Science Matters
Understanding the mechanisms behind heat therapy helps users:
Apply sauna intentionally
Choose the right type of sauna (traditional vs. infrared)
Use protocols optimized for specific goals
Improve longevity, cardiovascular health, and detox pathways
Stack sauna with nutrition, cold therapy, breathwork, or recovery tools
Science-backed knowledge leads to safer, more effective sauna habits—turning heat exposure into a structured, powerful wellness intervention.
