What does Stacy Sims say about infrared sauna vs finnish?

Stacy Sims prefers traditional Finnish saunas over infrared saunas. She notes that while infrared saunas warm the skin, they do not significantly heat the core body temperature, which is essential for the benefits associated with heat exposure. Finnish saunas, typically set between 60 to 80 degrees Celsius (140 to 176 degrees Fahrenheit), provide a more effective thermal stress that stimulates cardiovascular and metabolic benefits 1 2.

Dr. Sims emphasizes that everyone responds well to heat, but the benefits are maximized with proper sauna use, which Finnish saunas facilitate better than infrared versions 1.
