Measuring humidity in a traditional sauna is crucial for ensuring a comfortable and safe experience. As a traditional sauna supplier, I've witnessed firsthand how the right humidity levels can transform a sauna session. In this blog, I'll share some practical ways to measure humidity in a traditional sauna and explain why it's so important.
Why Humidity Matters in a Traditional Sauna
Before we dive into how to measure humidity, let's understand why it's such a big deal. In a traditional sauna, humidity plays a key role in how you feel. A lower humidity level (usually around 10 - 20%) gives you a dry heat experience. This is great for those who like a more intense, but less sticky, heat. It can help open up your pores and promote sweating, which is not only good for detoxification but also makes you feel relaxed and rejuvenated.
On the other hand, a higher humidity level (up to 40 - 50%) can make the heat feel more bearable. It can be less drying to your skin and respiratory system. Plus, it adds a bit of a steamy, spa - like atmosphere to your sauna session. But if the humidity gets too high, say above 60%, it can feel like you're in a hot, wet cave. It might even become uncomfortable and potentially dangerous, as it can make it harder for your body to cool down through sweating.
Tools for Measuring Humidity in a Traditional Sauna
Hygrometers
One of the most common and practical tools for measuring humidity is a hygrometer. These nifty little devices are designed to measure the amount of moisture in the air. There are several types of hygrometers that you can use in a sauna.
- Mechanical Hygrometers: These are the traditional type. They usually work based on the expansion and contraction of a hair or a piece of material in response to changes in humidity. They're simple to use and don't require batteries. All you need to do is hang it inside your sauna and read the humidity level off the dial. However, they might need to be calibrated every once in a while to ensure accurate readings. You can find mechanical hygrometers at many hardware or home improvement stores.
- Digital Hygrometers: These are more modern and offer a higher level of accuracy. They use sensors to measure humidity and display the results on a digital screen. Some digital hygrometers can even record minimum and maximum humidity levels over a period of time. They're a great option if you want to keep a close eye on the humidity in your sauna. They do require batteries, but it's a small price to pay for the convenience and accuracy they offer. You can often find digital hygrometers at electronics stores or online.
Smart Sensors
With the rise of smart home technology, smart sensors have also become a popular option for measuring humidity in a sauna. These sensors can connect to your smartphone or other smart devices via Wi - Fi or Bluetooth. They not only measure humidity but can also track other factors like temperature and air quality. Some smart sensors can even send you alerts if the humidity levels go out of the optimal range. This is really handy if you want to monitor your sauna's conditions even when you're not physically there. A lot of these smart sensors are available from tech companies that specialize in home automation products.
How to Use Humidity Measurement Tools in a Sauna
Once you've got your humidity measurement tool, using it properly is important to get accurate results.


Placement
The placement of your hygrometer or smart sensor can greatly affect the readings. You should place it in a central location in the sauna, away from direct heat sources like the sauna stove. If it's too close to the stove, the heat can cause the readings to be inaccurate. Also, avoid placing it near vents or doors, as the air movement in these areas can also skew the results. A good spot is about chest - height on a wall in the middle of the sauna.
Reading the Data
For mechanical hygrometers, simply read the humidity percentage off the dial. Make sure your eyes are level with the dial to get an accurate reading. With digital hygrometers and smart sensors, the humidity level will be displayed on the screen. Some smart sensors also come with apps that can provide more detailed information and graphs about the humidity over time.
Maintaining the Right Humidity in a Traditional Sauna
Measuring humidity is just the first step. Once you know the humidity level, you need to be able to adjust it if necessary.
Lowering Humidity
If the humidity in your sauna is too high, there are a few things you can do. First, you can open the sauna door slightly to let some of the moist air out. This will allow fresh, drier air to circulate inside. You can also reduce the amount of water you pour on the sauna stones. If you're using a steam generator, you can turn it down or turn it off completely.
Increasing Humidity
On the other hand, if the humidity is too low, you can pour more water on the sauna stones. The heat from the stones will turn the water into steam, increasing the humidity. You can also use a steam generator if your sauna is equipped with one. Just make sure not to overdo it, as too much humidity can make the sauna uncomfortable and potentially unsafe.
