Why do people wear those Hats?

Ever wondered why some sauna-goers wear those funny-looking hats? They’re not just for style—sauna hats are used for protecting your head from extreme heat. Without one, your head can overheat quickly, making your sauna session uncomfortable or even cutting it short.

Why Do You Need a Sauna Hat?

Hot air rises, meaning the temperature near your head can be 20-30°C hotter than at your feet. A sauna hat creates a protective barrier, slowing down heat absorption. This helps regulate your body temperature, making your sauna session longer and more enjoyable. Do you absolutely require one? No, normal sauna rituals are tailored to be enjoyable for all without hats. However do you really like the heat, and prefer the upper benches? then it may be wise to have one ready in case you need it.

Best Materials for Sauna Hats

Not all sauna hats are created equal. The material makes a huge difference in performance. the rule function over form does apply to this one!

Wool Felt (Best Choice) – Natural insulation, breathable, antibacterial, and durable. A proper wool sauna hat is 3-6mm thick for optimal protection.

Linen (Cooler Option) – Absorbs moisture well and stays breathable, great for humid saunas. Less insulation than wool but still effective.

Avoid Synthetic Felt & Cotton – Polyester and acrylic trap heat instead of regulating it, making your head even hotter. Cotton absorbs sweat but lacks insulation.

Size & Shape: What Fits Best?

A good sauna hat should fit snugly but not too tight. It should cover the top of your head and ears for full protection.

• Cone Shape: Creates an insulating air pocket, a traditional Finnish design.
• Bell or Bucket Style: Offers more coverage, ideal for those with longer hair.

How to Use & Care for Your Sauna Hat

• Wear it dry for maximum insulation (Finnish style) or soak it in cool water for extra cooling (Russian banya style).
• Air-dry after each use to prevent odors. Hand-wash occasionally with mild soap and cold water.
• Store in a dry, ventilated place to maintain its shape.

Conclusion

A sauna hat may seem like a small accessory, but it makes a huge difference. It protects your head, extends your sauna time, and adds comfort. Plus if you buy a nice one you’ll be the most fashionable person in the sauna as everyone else just brought their vanilla style 🙂
