42nd treatment shown to reduce risk in December 2023
 
*, now known with p = 0.026 from 4 studies.
Lower risk for recovery.
No treatment is 100% effective. Protocols combine complementary and synergistic treatments. * >10% efficacy in meta analysis with ≥3 clinical studies.

Prospective study of 2,275 middle-aged Finnish men showing significantly lower risk of future pneumonia with a combination of high cardiorespiratory fitness and frequent sauna bathing compared to each exposure alone. High cardiorespiratory fitness and frequent sauna bathing (2-7 sessions per week) were each independently associated with lower pneumonia risk after adjusting for potential confounders.
Study covers thermotherapy and exercise.
risk of case, 19.0% lower, RR 0.81, p = 0.02, treatment 333 of 1,475 (22.6%), control 196 of 800 (24.5%), adjusted per study, multivariable, model 3.
Effect extraction follows pre-specified rules prioritizing more serious outcomes. Submit updates

High fitness levels, frequent sauna bathing and risk of pneumonia in a cohort study: Are there potential implications for COVID‐19?
Setor K Kunutsor, Jari A Laukkanen
European Journal of Clinical Investigation, doi:10.1111/eci.13490
Pneumonia infection is the result of a complex inflammatory process where the lower respiratory tract suffers the invasion of an infective microorganism (viruses or bacteria). Major risk factors that predispose to pneumonia include smoking, obesity, underweight, excessive alcohol consumption and comorbid conditions such as asthma,
