A 20-year Finnish cohort study (Laukkanen et al., JAMA Internal Medicine, 2015 — PMID 25705824) found that sauna use four to seven times per week was associated with significant cardiovascular adaptation outcomes compared to once-weekly use. Heat shock protein activation through repeated heat exposure has been documented by Kregel KC (Journal of Applied Physiology, 2002) as associated with cellular stress adaptation and connective tissue recovery.\u003c\/p\u003e\n\u003cp class=\"font-claude-response-body break-words whitespace-normal leading-[1.7]\"\u003eThis unit reaches the temperature range used in that research.
