Sauna and Blood Pressure | How Sauna Affects Hypertension and Healthy Arteries

Regular sauna use lowers blood pressure, supports vascular elasticity, and improves cardiovascular health. Discover scientific studies and practical recommendations.

Introduction

High blood pressure is one of the most common health problems today. Many people seek natural ways to keep it under control alongside medication or a healthy lifestyle. Sauna is one such option – its effects on the blood vessels and heart are comparable to light exercise.

1. Clinical studies and evidence

Laukkanen T. et al. (2015)
A Finnish study on more than 1,600 men showed that regular sauna bathing (4–7 times per week) reduced the risk of hypertension by up to 47%.

2. Mechanism of effect of sauna use

1. Vasodilation (widening of blood vessels) – heat relaxes the smooth muscles of blood vessels, lowering pressure.
2. Improved vascular elasticity – regular sauna bathing strengthens vessel walls and enhances blood circulation.
3. Hormonal regulation – sauna reduces the stress hormone cortisol, which is associated with high blood pressure.

4. Risks and limitations

Sauna is not suitable during an acute hypertensive crisis. People with cardiovascular disease should consult their doctor before sauna use. It is important to avoid sudden cooling (e.g., ice water), which may sharply increase blood pressure.

6. Summary (scientific)

Studies confirm that sauna use has a beneficial effect on blood pressure – it lowers values, improves vascular elasticity, and generally supports the cardiovascular system.

Summary in human language

If you struggle with high blood pressure or want to protect your heart, the sauna can help. Heat relaxes the blood vessels, reduces tension, and gives you a sense of lightness. It is a simple way to naturally support your health.
