Introduction: The Heat That Heals
A 2018 study published in Mayo Clinic Proceedings found that regular sauna users had up to a 50% lower risk of cardiovascular disease compared to those who never used a sauna. Fifty percent! That’s not just a minor perk—that’s a life-changing difference.
Sauna bathing isn’t just about sweating and relaxation. It’s an ancient wellness practice that science is finally catching up with. From boosting heart health to reducing stress, improving lung function, and even lowering the risk of dementia, the benefits are surprisingly far-reaching. But let’s be clear: not all sauna sessions are equal. Too much heat, too long in the sauna, or skipping hydration? That’s a recipe for disaster.
In this guide, we’ll cut through the noise and show you exactly how to use a sauna the right way—maximizing benefits while avoiding the common mistakes that could do more harm than good. Whether you're a seasoned sauna-goer or considering your first session, this article will give you actionable, research-backed strategies to make your time in the heat work for you.
Types of Saunas: Which One Is Right for You?
Not all saunas are created equal. Each type has unique characteristics, and understanding them can help you pick the best option for your health goals.

How it feels: Dry heat, but you can control humidity with steam
2. Infrared Sauna
-
Temperature: 120–140°F (49–60°C)
-
Humidity: Low

Health Benefits of Sauna Use
1. Strengthens Your Heart & Lowers Blood Pressure
Frequent sauna use (4–7 times per week) can reduce the risk of heart disease, high blood pressure, and even stroke. The heat mimics the effects of moderate-intensity exercise, increasing circulation and improving vascular function.
2. Boosts Lung Function & Eases Respiratory Conditions
If you have asthma, chronic bronchitis, or seasonal allergies, sauna sessions might help. The warm air can loosen mucus and reduce inflammation in the lungs, making it easier to breathe.
3. Relieves Pain & Speeds Up Muscle Recovery
Saunas can help reduce muscle soreness, making them a great post-workout tool. Heat exposure increases blood flow, delivering oxygen and nutrients to tired muscles while flushing out lactic acid.
4. Lowers Stress & Improves Sleep
A sauna session isn’t just relaxing—it actively lowers cortisol (your stress hormone) while increasing endorphins (your body’s natural feel-good chemicals). The result? Better mood, reduced anxiety, and deeper sleep.
5. May Reduce the Risk of Dementia
In long-term studies, people who used saunas multiple times per week had a significantly lower risk of developing dementia and Alzheimer’s disease. While the exact mechanisms are still being studied, improved circulation and reduced inflammation seem to play a key role.
Common Questions Answered
Is It Safe to Use a Sauna Every Day?
For most healthy individuals, yes! Research suggests 4–7 sessions per week deliver the best benefits. However, if you’re new to sauna use, start with 1–2 sessions per week and gradually increase frequency.
How Long Should You Stay in a Sauna?
Beginners should aim for 5–10 minutes, while experienced users can go up to 20 minutes per session. Always listen to your body—if you feel lightheaded or overly fatigued, step out immediately.
Are There Any Risks to Sauna Use?
While generally safe, saunas aren’t for everyone. If you have unstable heart disease, low blood pressure, or severe dehydration, consult a doctor before use. Also, never mix saunas with alcohol—it increases the risk of dizziness, fainting, and heart complications.
