How Long Should You Stay in a Sauna? A Simple Guide

So you've got your beautiful new sauna, or you're about to get one. You're ready for that deep, restorative heat. But as you prepare for your first session, a simple but important question comes to mind: how long am I actually supposed to stay in here?

It's a great question. You want to relax and get all the amazing health benefits, but you also want to do it safely. Is longer always better? Is there a magic number?

Relax. The answer is simple. In this guide, we'll give you clear, science-backed recommendations for the perfect session length and share some pro tips to help you find your personal sweet spot.

The Golden Rule: Listen to Your Body

Before we get into numbers, this is the most important rule of sauna use: your body knows best. The goal is to feel relaxed and rejuvenated, not to endure a marathon. If you start to feel dizzy, nauseous, or just plain uncomfortable, it's time to step out, even if it's only been five minutes. No one's handing out medals for endurance here!

The 15-20 Minute Sweet Spot: Why It Works

For most healthy adults, the ideal sauna session lasts between 15 and 20 minutes. This is the sweet spot that science and tradition agree on. It's long enough for your body to experience the full therapeutic benefits—increased heart rate, deep sweating, and muscle relaxation—without pushing it into a state of excessive stress or dehydration.

For Beginners: If you're new to sauna use, start with shorter sessions of 5 to 10 minutes to see how your body acclimates. You can gradually work your way up to longer sessions as you become more comfortable.

Tailoring Your Session: Infrared vs. Traditional

The type of sauna you're using can also influence your session length.

In a traditional sauna, the high ambient heat (160-195°F) is intense. Shorter, 15-minute sessions are often perfect. Some experienced users enjoy doing multiple short "rounds" with cool-down breaks in between.
In an infrared sauna, the heat is gentler (120-140°F) and warms your body directly. This often allows for longer, more relaxed sessions of 20-30 minutes without feeling overwhelmed.

Beyond the Basics: Cool-Downs and Frequency

A great sauna session doesn't end when you step out of the heat. The cool-down is just as important, and finding the right frequency is key to long-term benefits.

The Importance of the Cool-Down

After your heat session, allow your body at least 10-15 minutes to cool down naturally. A lukewarm or cool (but not ice-cold) shower is a perfect way to rinse off the sweat and gently bring your body temperature back to normal. This hot/cold cycle is fantastic for boosting circulation and leaves you feeling incredibly refreshed and energized.

How Many Times a Week Should I Sauna?

Consistency is more important than intensity. For most people, 3 to 4 sessions per week is a fantastic goal to experience the cumulative health benefits. Some dedicated enthusiasts sauna daily. Start with a couple of sessions a week and see how your body responds. The best frequency is the one you can comfortably maintain.

The Home Sauna Advantage: Consistency is Key

The real secret to unlocking the long-term health benefits of a sauna isn't one perfect session; it's consistency. And the easiest way to build a consistent routine is by having your own home sauna.

Owning your own sauna gives you the freedom to listen to your body without pressure. There's no rush to finish because someone else is waiting. You can find your perfect 17-minute sweet spot and make it a non-negotiable part of your daily routine. This convenience is what transforms a casual habit into a powerful wellness ritual.

"Having our own sauna at home has been a game-changer. I've found my perfect routine is 20 minutes, three times a week. I sleep so much better and my joints have never felt better. It’s a level of consistency you just can’t get at a gym."

- Mark D., Verified Buyer

Pro Tip: Hydrate Before, During, and After

Always drink a glass of water before you go in, and have a water bottle handy. After your session, continue to rehydrate to replenish the fluids you've lost through sweat. This is the most important safety rule for a great sauna experience.

Important Health Note: The information in this guide is for educational purposes only. If you have a health condition (especially cardiovascular issues), are pregnant, or take medications, you must talk with your doctor before starting a new sauna routine.

The Final Takeaway

While 15-20 minutes is the recommended duration for a sauna session, the most important clock to watch is your own body's. Start slow, stay hydrated, and focus on how you feel. By listening to your body, you'll find the perfect rhythm and duration to make every sauna session a safe, relaxing, and deeply beneficial experience.
