The infrared sauna operates differently from a traditional Finnish sauna in one key respect: instead of heating the air to high temperatures, infrared panels emit radiant heat that warms the body directly at lower ambient air temperatures — typically 50–60 degrees Celsius rather than the 80–100 degrees of a traditional sauna. This difference has practical implications for the sauna hat.

Do you need a sauna hat in an infrared sauna? The primary function of the traditional sauna hat is to insulate the head from the very high ambient air temperature of the Finnish sauna — air at 85–95 degrees. In an infrared sauna at 55 degrees ambient air temperature, the head is not exposed to the same extreme air temperature, which reduces the primary insulating need.

However, infrared panels do emit radiant heat directly, and many infrared sauna users find that the head and scalp benefit from some protection from the direct radiant exposure, particularly in longer sessions above 30 minutes. A natural wool felt hat in an infrared sauna may reduce some direct radiant exposure to the scalp and hair, in a similar way to how it moderates ambient air heat in a traditional sauna.

Hair protection in the infrared context. The hair protection benefit of a sauna hat — reducing direct heat exposure to the hair shaft — is relevant in an infrared sauna as well as a traditional one. The radiant heat from infrared panels reaches the hair directly; a wool felt hat provides the same protective layer in this context.

The PP natural wool sauna hat in an infrared sauna. The same natural wool felt construction that works in the traditional Finnish sauna works in the infrared context. The material is natural, the construction is appropriate, and the hair protection benefit applies in both environments.
