Plain-English Summary
FDA has warned that whole-body cryotherapy claims can outrun evidence and pose risks. This helps separate cold-water recovery evidence from broader cold-exposure wellness claims.

How the study framework works ->Key Findings
- FDA has warned that whole-body cryotherapy claims can outrun evidence and pose risks.
- This helps separate cold-water recovery evidence from broader cold-exposure wellness claims.
Limitations
- Whole-body cryotherapy is not the same exposure as a cold plunge.
- Consumer update, not a trial.

Sauna, Cold Plunge, and Contrast Therapy: Hormesis or Heart-Stress Theater?
Sauna has a stronger long-term cardiovascular and mortality signal than most cold-plunge claims. Cold exposure has acute physiology, mood appeal, and recovery tradeoffs. Contrast therapy adds ritual, but not automatic evidence.
