Is Sauna Good For Blood Circulation?

Our bodies operate through an elaborate vascular network, comprising arteries, veins, and capillaries. This vital system tirelessly pumps oxygen-enriched blood to every cell, delivering indispensable nutrients.


More than a mere transport mechanism, circulation plays an instrumental role in various physiological processes—from oxygen distribution and waste removal to supporting respiratory and digestive systems and even temperature regulation. Envision this system as our body's crucial superhighway, facilitating the seamless flow of nourishment and detoxification.


Yet, disruptions to this pathway—arising from issues like blood clots, inflammation, trauma, or genetic predispositions—can usher in perilous vascular diseases. In the face of such potential risks, bolstering our circulatory health is essential.


Beyond its serene warmth, the sauna emerges as a promising ally for circulation enhancement. But is sauna good for blood circulation? And if so, how exactly does sauna help with blood circulation? Additionally, what are the benefits of improved circulation that make adopting a sauna protocol worthwhile? We explore these questions below with the latest data.

How Do Saunas Help with Circulation?

When exposed to the high temperatures of a sauna, our bodies initiate a series of circulatory changes. A significant 50 to 70 percent of our internal blood flow is rerouted from our core organs toward the skin's surface. This redirection aids the sweating process, an essential mechanism for body cooling.

Additionally, there's an uptick in our plasma volume. This additional plasma not only ensures we have ample fluid to sustain sweating but also serves a vital cooling role, helping the body maintain its optimal temperature.

Together, these adjustments enhance our body's heat tolerance and ensure optimal blood circulation, leading to a variety of short and long-term benefits. Here are three ways you can use sauna for blood circulation to benefit your overall health:

Three Ways Sauna for Blood Circulation Supports Overall Health

1. Reduced Risk of Vascular Disease

Scientific research strongly supports the healthful benefits of saunas, particularly their potential to bolster cardiovascular health and, by extension, enhance our overall longevity.

Evidence consistently points to the effectiveness of saunas in mitigating the risks associated with vascular diseases. Regular 30-minute sauna sessions have been shown to help regulate both systolic and diastolic blood pressure. In fact, individuals who make sauna baths a part of their regular routine have reported an impressive 47% decrease in hypertension risk over extended periods.

Saunas also seem to offer a protective shield against a myriad of cardiovascular dangers, including sudden cardiac events, fatal coronary conditions, and strokes. To illustrate, the  Kuopio Ischemic Heart Disease Risk Factor (KIHD) Study—a comprehensive cohort study involving over 2,300 middle-aged men from eastern Finland—provided a revealing insight: men engaging in routine sauna sessions had a 27% lower chance of cardiovascular-related death than those who did not.

This advantage became even more pronounced among frequent users: those partaking in sauna baths between four to seven times a week saw this risk drop by 50% compared to those who used the sauna once per week, a statistic that remained consistent across varying age groups, activity levels, and lifestyle choices.

Such compelling evidence underscores the potential benefits of incorporating saunas into daily routines. The consistent use of saunas may not only improve blood pressure but can also enhance endothelial and left ventricular functions. When combined with regular physical activity, the potential cardiovascular benefits of saunas become even more pronounced.

 2. Reduced Risk of Chronic Inflammation

Chronic inflammation plays a significant role in cardiovascular health by damaging blood vessels and impeding optimal blood flow. This persistent inflammatory state is often linked to various heart and circulatory conditions, such as atherosclerosis, arterial stiffness, and heart disease. The liver produces C-reactive protein (CRP), which is an indicator of inflammation. High CRP levels suggest inflammation and are tied to serious conditions like atherosclerosis

A noteworthy 2017 study involving 2,084 men aged between 42 and 60 highlighted the potential benefits of sauna use in managing inflammation. The findings revealed that frequent sauna users had lower CRP levels, suggesting that saunas might aid in reducing inflammation.

Specifically, of the participants, 533 men used the sauna weekly, 1,368 used it 2-3 times a week, and 183 indulged 4-7 times a week. The correlation between sauna use and decreased CRP levels implies that saunas could be a valuable tool in combating chronic inflammation and its adverse effects on vascular health.

3.Improved Muscle Recovery & Detoxification

Inside the warm embrace of a sauna, the body secretes endorphins, known for their pain-relieving properties similar to the “runner's high” sensation experienced by athletes. As the sauna's heat elevates the body's core temperature, blood vessels expand, enhancing circulation.

This amplified blood flow not only infuses muscles with fresh oxygen and nutrients but also efficiently removes metabolic waste, facilitating its return to the kidneys for elimination. Such efficient circulation aids in quicker muscle recovery, reduces post-workout soreness, and promotes healthier tissue. Moreover, well-nourished tissues are less prone to injuries, and if injured, they heal more swiftly, even post-surgery.

In Conclusion

Poor circulation stands as a silent threat, with the potential to manifest in numerous health issues ranging from fatigue and numbness to more severe complications such as vascular diseases and heightened risks of strokes. In such a landscape, saunas have emerged not merely as sanctuaries of relaxation but as potent tools for supporting circulatory health.


Grounded in scientific evidence, saunas are shown to fortify robust blood circulation, a benefit that extends far beyond surface-level wellness. Enhanced circulation contributes to improved recovery post-exertion, a marked reduction in the risk of vascular diseases, and a significant decrease in fatalities related to cardiovascular events. By comprehending the invaluable link between saunas and blood circulation, we are offered a tangible route to both enriching and extending the quality of our lives.
