Exploring the Jama Network Study: Sauna Bathing and Mortality Events

Sauna bathing has been a popular practice for centuries, and its potential health benefits have intrigued researchers worldwide. In a groundbreaking study titled “Association Between Sauna Bathing and Fatal Cardiovascular and All-Cause Mortality Events,” published in the Jama Network, researchers shed light on the connection between sauna bathing and mortality events. In this blog post, we will outline the key findings of this study and explore the potential implications for our understanding of sauna bathing and its impact on our health.

Study Design and Participants:

The Jama Network study involved a comprehensive analysis of a large population cohort from Finland. The researchers collected data from over 2,300 middle-aged men, tracking their sauna bathing habits and health outcomes over an extended period. This longitudinal study design allowed for robust and meaningful insights into the association between sauna bathing and mortality events.

Sauna Bathing and Cardiovascular Mortality:

The study revealed a remarkable association between regular sauna bathing and reduced risk of cardiovascular mortality. The participants who engaged in frequent sauna sessions experienced significantly lower rates of fatal cardiovascular events compared to those with less frequent sauna use. This finding suggests a potential protective effect of sauna bathing on cardiovascular health.

All-Cause Mortality:

In addition to cardiovascular mortality, the study also explored the impact of sauna bathing on all-cause mortality. The results demonstrated a clear inverse relationship between regular sauna use and all-cause mortality. Participants who engaged in frequent sauna sessions 2-3 times per week were associated with 24% lower all-cause mortality and 4-7 times per week decreased all-cause mortality by 40%.  A substantially lower risk of premature death from various causes compared to those who sauna bathed infrequently.

Potential Mechanisms:

The exact mechanisms through which sauna bathing exerts its positive effects on mortality risk are not yet fully understood. However, the study suggests that the elevated heart rate and increased body temperature during sauna sessions may contribute to improved cardiovascular function and reduced inflammation, which are associated with better overall health outcomes.

Considerations and Future Research:

While the findings of this study are intriguing, it is important to note that the participants were predominantly middle-aged men from Finland, limiting the generalizability to other populations. Further research is needed to explore the potential benefits of sauna bathing in diverse populations and too elucidate the underlying mechanisms involved.


The Jama Network study on sauna bathing and mortality events provides compelling evidence of the potential health benefits associated with regular sauna use. The findings suggest that sauna bathing may significantly reduce the risk of cardiovascular and all-cause mortality. However, more research is required to fully understand the mechanisms at play and to validate these findings in broader populations. In the meantime, incorporating sauna bathing into a healthy lifestyle may offer a potential avenue for promoting cardiovascular health and overall well-being. As always, it is important to consult with healthcare professionals before initiating any new health practice.
