Basics of Lifespan
Before discussing how sauna use may impact lifespan, let's define what we mean by lifespan. In simple terms, it refers to the length of time a living organism is expected to live based on factors such as genetics and lifestyle habits.
In humans, average lifespan varies across different countries, with Monaco having the highest average lifespan of 89 years for women and 84 for men and Lesotho having the lowest at 50 years (Development aid Organization, 2024). It is important to note that while genetics and epidemics HIV/AIDS do play a role in determining lifespan, lifestyle factors can also significantly influence longevity.
Now, let's dive into how sauna use fits into this equation.

The Studies
There have been several studies exploring the potential link between regular sauna use and increased lifespan. Here are some noteworthy findings:
Cardiovascular Health
Among all causes of mortality, cardiovascular disease remains the leading cause of death globally. This is where much of the research on sauna use and lifespan has focused.
A study by T. Laukkanen and colleagues set out to investigate the association between sauna use and fatal cardiovascular and all-cause mortality events. The study was conducted on a population-based sample of 2315 men from Eastern Finland, aged 42 to 60 years. These participants were followed for a median time of 20.7 years.
Participants reported their sauna bathing habits at baseline, including frequency (1, 2-3, or 4-7 times per week) and duration (less than 11 minutes, 11-19 minutes, or more than 19 minutes). Hazard ratios were calculated using Cox proportional hazard models after adjusting for cardiovascular risk factors.
During the study period, there were 190 sudden cardiac deaths, 281 fatal coronary heart disease events, 407 fatal cardiovascular disease events, and 929 all-cause mortality events. The study found that for every additional sauna session per week, the risk of sudden cardiac death decreased by 22%.
Similar associations were seen for coronary heart disease, cardiovascular disease, and all-cause mortality. Additionally, longer sauna sessions were associated with a lower risk of all-cause mortality, with participants who spent more than 19 minutes in the sauna having a 52% lower risk compared to those who spent less than 11 minutes.
The results of this study suggest that increased frequency and duration of sauna bathing may have a protective effect against cardiovascular and all-cause mortality. In the meantime, incorporating regular sauna use into one's health habits may be beneficial for overall longevity.
Blood Pressure
High blood pressure, just like cardiovascular disease, remains a significant risk factor for mortality. A study by T. Laukkanen and colleagues sought to investigate the effects of sauna bathing on cardiovascular function and blood-based biomarkers in individuals with at least one cardiovascular risk factor. The study included 102 participants, with a mean age of 51.9 years and 56% being male.
The participants were exposed to a single sauna session lasting 30 minutes, with a temperature of 73 °C and humidity ranging from 10-20%. Cardiovascular parameters and blood-based biomarkers were collected before, immediately after, and after a 30-minute recovery period.
The results showed a significant decrease in arterial stiffness, as evidenced by the mean carotid-femoral pulse wave velocity decreasing from 9.8 m/s to 8.6 m/s immediately after sauna bathing (p < 0.0001). There was also a decrease in mean systolic blood pressure from 137 mmHg to 130 mmHg and diastolic blood pressure from 82 mmHg to 75 mmHg after sauna exposure (p < 0.0001). These changes in blood pressure were still evident even after the recovery period.
The study demonstrated that sauna bathing for 30 minutes had beneficial effects on both arterial stiffness and blood pressure in individuals with cardiovascular risk factors. The findings suggest that regular sauna use may be associated with reduced risk of hypertension and related cardiovascular events, potentially contributing to a longer lifespan.
Cognitive Benefits
Another aspect of health that has been linked to sauna use and longevity is cognitive function. Several studies have found a positive association between regular sauna use and improved cognitive abilities.
One study by T. Laukkanen and colleagues explored the relationship between sauna bathing and the risk of dementia and Alzheimer's disease in middle-aged Finnish men. This prospective, population-based study included 2,315 apparently healthy men aged 42-60 years at baseline. The frequency of sauna bathing was assessed at baseline between 1984 and 1989.
After a median follow-up period of over 20 years, the results showed that moderate to high frequency of sauna bathing (4-7 times per week) was associated with a significantly lower risk of developing dementia and Alzheimer's disease compared to those who only used the sauna once a week.
This association remained even after adjusting for potential confounders such as age, alcohol consumption, body mass index, systolic blood pressure, and smoking status. Further studies are needed to understand the potential mechanisms behind this link between sauna bathing and improved cognitive function.
Overall, these findings suggest that regular sauna use may have a protective effect on brain health and could potentially contribute to a lower risk of developing memory diseases later in life. Therefore, incorporating sauna bathing into one's routine may offer not only physical benefits but also cognitive benefits as well.
So, it is something worth considering for improving overall health and longevity. So, taking breaks from work to relax in the sauna can be both enjoyable and beneficial for your health.
Insulin Sensitivity and Metabolic Health
Studies suggest that sauna use can improve insulin sensitivity and reduce the risk of metabolic syndrome. This is particularly beneficial in managing obesity and type 2 diabetes, which are significant factors affecting lifespan.
A study by V. Shiralkar and colleagues investigated the effect of steam sauna baths on fasting blood glucose levels. The study was conducted on 80 healthy adults between the ages of 30 to 50 years, with an equal distribution of males and females.
The participants were subjected to seven steam sauna baths, each lasting for 15 minutes at a temperature of 50°C. Blood samples were taken before the first bath and after the seventh bath to measure fasting blood glucose levels.
The results showed a significant decrease in fasting blood glucose levels after completing the seven steam sauna baths. This indicates that regular use of steam saunas can aid in preventing hyperglycemia and possibly even diabetes mellitus. These findings are beneficial for both symptomatic individuals as well as healthy individuals looking to maintain their metabolic health.
This study provides evidence supporting the potential benefits of steam sauna baths on insulin sensitivity and metabolic health. This is crucial in the context of lifespan, as maintaining good metabolic health is essential for overall longevity. Thus, incorporating sauna use into one's routine may contribute to a longer and healthier life.
Detoxification and Immune Support
Sweating in a sauna helps remove toxins from the body, including heavy metals and other pollutants. This detoxification process can enhance immune function and support overall health.
A study by S. Genuis and colleagues explored the concentration of toxic elements in blood, urine, and sweat samples from 20 individuals. The study found that many toxic elements were excreted through sweat at varying degrees. In fact, some toxic elements were preferentially excreted through sweat rather than through other means, such as urine or feces.
The study also showed that induced sweating may be a potential method for eliminating bio accumulated toxic elements from the body. This is significant because traditional methods of monitoring biomarkers for toxic element exposure, such as blood and urine tests, may underestimate the total body burden of these substances.
Based on these findings, sweat analysis should be considered as an additional method for monitoring the bioaccumulation of toxic elements in humans. This supports the use of sauna therapy as a way to aid in detoxification and support immune function.
In summary, sweating in a sauna has been shown to have potential benefits for detoxification and immune support through the elimination of bioaccumulated toxic elements. Meaning, incorporating regular sauna use into one's health habits may contribute to a healthier and longer life.
So, along with proper nutrition and exercise, sauna bathing can be an effective tool for promoting overall longevity.
Reduction in Inflammation and Oxidative Stress
Regular sauna use may lower systemic inflammation and oxidative stress levels, contributing to reduced risks of chronic diseases and potentially extending lifespan.
A study by S.Kunutsor and colleagues examined the association between sauna bathing frequency and levels of inflammatory markers, specifically high sensitivity C-reactive protein, fibrinogen, leucocyte count, and gamma-glutamyltransferase.
The study was conducted on a large sample of 2269 men aged 42-61 years, with baseline and 11-year follow-up measurements taken for the inflammatory markers.
The results showed that frequent sauna use, defined as 4-7 sessions per week, was associated with lower levels of high sensitivity C-reactive protein, fibrinogen, and leucocyte count at baseline and 11-year follow-up compared to those who only used the sauna once a week. However, there was no significant difference in levels of gamma-glutamyltransferase.
Therefore, this population-based prospective cohort study supports previous observational evidence suggesting that saunas may have beneficial effects on systemic inflammation levels. The authors recommend further research to explore the mechanisms behind this association and the potential long-term health benefits of sauna use.
With its low cost and accessible nature, sauna bathing may be a simple yet effective way to improve overall health and well-being. Lastly, these findings also highlight the importance of considering non-pharmacological interventions in disease prevention and management.
Overall, this study adds to the growing body of evidence supporting the positive impact of regular sauna use on inflammation markers and underscores the potential benefits of incorporating sauna bathing as part of a healthy lifestyle.
