Saunas are often seen as a way to relax. But in recent years, their role in supporting cardiovascular health has drawn serious interest from the medical community. Long-term studies, especially those from Finland where sauna culture is widespread, have uncovered patterns that are difficult to ignore.
These findings go beyond comfort. They point to real, measurable changes in heart health for people who use saunas regularly.
Heart Benefits Backed by Long-Term Research
One of the most influential studies on sauna use was published in JAMA Internal Medicine in 2015. It followed over 2,300 middle-aged men in Finland for two decades. The results showed that those who used a sauna four to seven times per week had a 50% lower risk of death from cardiovascular disease compared to those who used it only once per week.
This connection has been observed in other studies too. A 2018 paper in Mayo Clinic Proceedings noted that sauna bathing is associated with improved vascular function, lower blood pressure, and reduced arterial stiffness, all markers linked to better heart performance.
What Happens to the Heart in the Sauna?
When you step into a sauna, your heart rate increases. It can rise to 100–150 beats per minute during a typical session, similar to light or moderate exercise. Blood vessels expand, improving circulation and helping the body regulate temperature.
This cardiovascular response helps condition the heart and blood vessels, just like aerobic activity. For people who may not be able to exercise intensely due to injury, age, or health conditions, sauna use offers a way to get similar circulatory benefits without strain.
There is also growing evidence that sauna use helps the body recover after exercise. Reduced inflammation, faster clearance of metabolic waste, and improved oxygen flow are all part of this process.
Regular Use Matters More Than Intensity
The benefits are not tied to extreme heat or long sessions. Consistency is more important. Studies show that 15–20 minutes in a sauna, done three to four times a week, can support cardiovascular resilience over time.
Sauna bathing has also been linked to lower risks of high blood pressure, a major risk factor for stroke and heart attacks. According to the American Journal of Hypertension, people who use saunas regularly show better systolic and diastolic blood pressure control over time.
