Do You Need a Wool Sauna Hat in an Infrared Sauna?

A wool sauna hat is optional in an infrared sauna. If you feel comfortable with your head uncovered, you can go without one for the entire session. If you already own a wool felt hat for a Finnish sauna or banya, you can try it in the infrared cabin and see how the heat feels with your head and hair covered.

Why Infrared Sauna Heat Feels Different

In a traditional sauna, a stove heats the room and you feel the warmth of the hot air around you. In an infrared sauna, the panels send radiant heat toward your body and nearby surfaces. The cabin air warms up too, but infrared cabins typically operate around 113–140°F (45–60°C), compared with 176–212°F (80–100°C) in a traditional Finnish sauna. 

You might feel more warmth on the side of your body facing a panel, even when the air feels mild. If the heat feels too intense in one spot, try sitting a little farther from the panel if the layout allows, or choose a lower setting. In a hybrid cabin with both infrared panels and a sauna stove, the active heating mode also changes how the room feels. 

Both infrared and traditional saunas can make you sweat, increase blood flow to the skin, and temporarily raise your heart rate. The warmth can feel relaxing, and some people find it soothing after exercise. Researchers have also studied infrared sauna use for joint conditions and headaches, but larger studies are needed to establish whether it helps with these conditions. 

Warmup, Frequency, and Safety

The lower air temperature in an infrared cabin may feel gentler if you find a traditional sauna too hot. Children and older adults can be more sensitive to heat, so follow the cabin’s age and supervision rules for children. Shorter sessions may be more suitable for older adults. If you have a heart or circulation condition, check with a healthcare professional before starting a sauna routine.

Warmup time varies by model. Harvia’s cabin guide gives a warmup time of under 10 minutes, while Sunlighten’s first-session guide recommends 45 to 60 minutes of preheating. You may feel warmth from the panels as the cabin air is still warming. The heat setting and session length both affect how much your body warms. 

Some manufacturers, including Harvia, describe daily infrared use as an option. Frequent traditional sauna use has also been studied. One Finnish observational study included adults who used a traditional sauna four to seven times a week. How often to go depends on the temperature, the length of each session, and how well you tolerate the heat. 

Many infrared cabins have a digital panel for setting the time and temperature. The heaters and lamps can still cause contact burns, so keep clear of them while the sauna is running. 

Water, a Quick Rinse, and Two Towels

Plain water or unsweetened mineral water is a good choice before your session. Keep some nearby to sip during the session, and drink water afterward to replace what you lose through sweat. If you’re hungry beforehand, a light snack may feel more comfortable than a full meal right before you go in. 

A quick warm shower before your session is optional. If you rinse off, towel-dry before entering. Clearlight also recommends leaving body lotions and oils until afterward. Two clean towels come in handy. The larger one goes on the bench, and the smaller one is for dabbing away sweat as needed. 

For a first session, a lower temperature and a short visit give you time to see how the heat feels. If you feel dizzy or nauseated, step out of the sauna right away.

How to Choose a Wool Sauna Hat

Wool felt adds a layer over the areas it covers, which can change how the heat feels around your head. A good fit sits comfortably around your forehead and leaves enough room at the top for your hair. If you usually wear a bun in the sauna, check the crown height as well as the head circumference. The depth of the hat also determines how much of your ears and the back of your head it covers.

MySaunaHut hats come in different shapes, so the fit can vary even between models labeled XL. Measure around the widest part of your head, just above the eyebrows and ears, then check the measurements for the model you like. For a starting point, see our sauna hat size guide.

A wool felt hat is best worn dry. After your session, hang it somewhere ventilated and let it air-dry completely before storing it.
