Why Doctors Are Recommending Saunas For Heart Health

Regular sauna use is no longer just a wellness trend—it’s becoming a doctor-recommended habit for supporting heart health. Backed by studies from major research institutions, saunas are being recognized for their ability to lower blood pressure, improve circulation, and reduce the risk of heart disease.

What the Research Says About Sauna and Heart Health

One of the most well-known studies on sauna use and cardiovascular health comes from the University of Eastern Finland. Researchers followed over 2,000 men for 20 years and found that those who used a sauna 4–7 times per week had a 50% lower risk of fatal heart disease compared to those who used a sauna only once per week.

During a sauna session:

• Heart rate increases, similar to light exercise
• Blood vessels expand, improving blood flow
• Body temperature rises, stimulating beneficial cardiovascular responses

How Saunas Help Lower Blood Pressure

High blood pressure is one of the leading risk factors for heart disease. A 2018 study found that even a single sauna session can lead to a temporary drop in both systolic and diastolic blood pressure. Regular sauna use may support long-term blood pressure control by improving blood vessel flexibility and reducing inflammation.

Infrared vs. Traditional Sauna: Which Is Better for the Heart?

Both types of saunas support heart health, but infrared saunas are especially popular with those looking for a gentler, more accessible option. They operate at lower temperatures while still delivering deep heat that supports circulation and heart rate.

Infrared sauna heart health benefits include:

• Longer, more comfortable sessions
• Deeper tissue warming for improved blood flow
• Gentler on those with heat sensitivity or chronic health conditions

Other Heart-Healthy Benefits of Sauna Use

Beyond circulation and blood pressure, sauna use offers other indirect cardiovascular benefits:

• Stress relief – Saunas lower cortisol levels and promote deep relaxation
• Better sleep – Improved sleep quality supports overall heart function
• Reduced inflammation – Studies show saunas can reduce C-reactive protein (CRP), a marker for inflammation

When to Talk to Your Doctor

While sauna use is safe for most people, those with existing heart conditions, very low blood pressure, or recent cardiac events should consult their doctor before beginning a sauna routine.

Sauna therapy is a supportive habit—not a replacement for medical treatment.

Final Thoughts

With increasing scientific evidence and growing medical support, sauna use is a proven way to support cardiovascular health. Whether you’re aiming to lower your blood pressure, improve circulation, or simply feel better day to day, a quality sauna can be a powerful addition to your wellness routine.
