Sauna use exploded in wellness culture, driven by longevity research from Dr. Rhonda Patrick and Finnish population studies. Infrared saunas, barrel saunas, and DIY builds flooded Instagram. Heat exposure linked to cardiovascular benefits, longevity.
Scientific Support
- Finnish studies - 4-7 sauna sessions/week = 50% lower cardiovascular death risk
- Heat shock proteins - Longevity, cellular repair mechanisms
- Detoxification claims - Mixed evidence, mostly sweat = water
Sauna Types
- Traditional Finnish - Dry heat, 160-200°F, wood-burning or electric
- Infrared - Lower temps (120-140°F), deeper tissue penetration claims
- Barrel saunas - Outdoor, wood-fired, Instagram aesthetic
Protocol Trends
- 20 min sessions - 3-7x/week for health benefits
- Contrast therapy - Sauna → cold plunge cycles
- Post-workout - Recovery, muscle relaxation
Market Boom
Barrel sauna Etsy shops thrived. Infrared home saunas (Sunlighten, Clearlight) sold out. Gym sauna usage spiked.
