Is ventilation required for infrared saunas?

Infrared saunas do not typically need to be vented. Unlike traditional saunas that use hot air to heat the room, infrared saunas use infrared heaters to emit radiant heat that is absorbed by the body. This type of heating system does not generate significant amounts of airflow, so venting is generally not required. However, it’s important to ensure that the sauna has proper insulation and air circulation to maintain a comfortable and safe environment while in use.

What does venting the infrared sauna do?

To allow heat and oxygen to properly flow through the sauna, a small gap under the door or something similar will usually suffice. This also helps the sauna wood to dry out between uses, keeping the environment healthy. All of which is already incorporated in most infrared sauna designs.
