Why Sauna Lowers Blood Pressure (Backed by Science)

One of the most fascinating health benefits of regular sauna use is lower blood pressure. In fact, a 2017 study published in the American Journal of Hypertension showed that people who used a sauna 4–7 times a week had a 46% lower risk of developing high blood pressure than those who used it only once per week.

These findings raise an important question for anyone focused on heart health.

So how does a sauna lower blood pressure?

The Science of Heat and Your Heart

When you sit in a sauna, your body temperature rises and blood vessels widen — a process called vasodilation. This causes:

• Better blood circulation

• Reduced vascular resistance

• Temporary decrease in blood pressure levels

It mimics the effects of light aerobic exercise — without leaving your home.

✅ Is It Safe to Use a Sauna If You Have High Blood Pressure?

Yes — saunas are generally safe for individuals with stable hypertension. In fact, they may improve arterial function and reduce long-term cardiovascular risk. However, follow these tips:

• Stay hydrated before and after each session

• Avoid sessions longer than 20 minutes

• Don’t use extremely high temperatures as a beginner

• Cool down gradually, not with extreme cold

• Always consult your doctor, especially if you take blood pressure medications

How Often Should You Use a Sauna?

Based on scientific research, the ideal routine is:

• 3 to 5 sessions per week

• Each session: 15–20 minutes

• Temperature: 150°F to 170°F (65°C–77°C)

Remember: Consistency is key. Long-term use leads to the most noticeable blood pressure benefits.

Sauna + Exercise = Even Better Results

Using a sauna after a workout can:

• Help stabilize post-exercise blood pressure

• Accelerate muscle recovery

• Lower cortisol (stress hormone)

Combining sauna with movement and hydration creates a heart-healthy lifestyle you can feel.
