How to Use Wood-Fired Saunas Safely

 

A wood-fired sauna brings a classic, authentic experience—crackling flames, radiant heat, and the soothing scent of cedar. But with that rustic charm comes a serious responsibility: safety. Whether you're new to sauna ownership or a seasoned user, knowing how to operate your wood-fired or wood-burning sauna safely protects not just your investment and property, but also your well-being.

Before you light that first match, here’s what you should know:

1. Choose a Safe Location
Start with the right spot. Place your sauna on a flat, stable surface that’s free from flammable surroundings—keep it well away from trees, overhangs, sheds, or fences. Proper airflow is essential, so allow enough open space around the sauna to avoid smoke or heat buildup.

2. Install a Heat Shield
Your stove should be installed with sufficient clearance from the sauna walls. Even though high-quality cedar—like what Northern Lights uses—offers natural heat resistance, adding a stainless-steel heat shield behind the stove gives extra fire protection and peace of mind.

3. Burn the Right Wood
Use only seasoned hardwoods such as oak, maple, or birch. These woods burn clean and hot, making them perfect for saunas. Avoid treated, painted, or softwoods, which can release harmful fumes. Keep your firewood dry and store it well away from the sauna to prevent accidental ignition.

4. Never Leave the Fire Unattended
Even a short break can be risky. Always make sure someone is supervising the fire during use. Wood-fired saunas heat up gradually, giving you plenty of time to monitor and manage the temperature safely.

5. Monitor the Temperature
The ideal sauna temperature ranges between 150°F and 190°F. Going beyond that can lead to overheating, health risks like dizziness or dehydration, and even damage to the wood. A sauna-safe thermometer helps you keep the heat in check.

6. Ensure Good Ventilation
Ventilation isn't just for comfort—it's vital for safety. Quality saunas like Northern Lights' barrel saunas come equipped with air intake and exhaust vents to maintain fresh airflow and prevent carbon monoxide buildup. Never block or cover these vents.

7. Keep a Fire Extinguisher Handy
It’s a simple step that could save your sauna—and more. Mount a fire extinguisher nearby, in a dry, accessible spot, but not directly exposed to sauna heat or moisture.

8. Stay Hydrated
Sauna sessions cause you to sweat—A LOT. Rehydrate with water before and after your session. Skip alcohol, as it increases dehydration and impairs your ability to safely monitor the heat.

Respect the Fire, Enjoy the Experience
A wood-fired sauna is more than just a way to unwind—it’s a fire-powered retreat that demands respect and care. Follow these safety tips, and your sauna will reward you with years of safe, blissful relaxation.
