Do saunas help you lose weight?

The short answer is yes—with some restrictions. Saunas generally promote weight reduction by sweating, which allows the body to shed water weight momentarily. During a typical 30-minute sauna session, you can lose roughly 0.1 to 0.6 kg (0,22 to 1,32 pounds). However, this is primarily water weight, which will return as you rehydrate.

Sauna bathing offers numerous health benefits, including weight control, hormonal balance, cardiovascular health benefits, musculoskeletal pain relief, muscle pain reduction, respiratory system benefits, and relaxation. It promotes a deep state of relaxation, reduces stress, and improves overall well-being.

Who should avoid or limit sauna sessions?

Sauna baths are safe for most healthy individuals, but precautions are needed for those with specific conditions like acute infections, heart problems, or fever. Heat exposure can affect certain drugs’ pharmacokinetics, so high blood pressure medicines should be taken before use. Also, saunas are safe for children to use under adult supervision.

A Personal Experience

Finding Resonance

In the world, everything has a resonant frequency. From a board, to the engine in your car. We’ve captured this into instruments such as the marimba. A simple line of wood specifically sized to create notes. That note harmonizing perfectly with each other piece of wood comes together into beautiful music when played skillfully. In sauna design, we feel the same. Bringing together finishes, materials and textures that harmonize together to create a masterpiece. Perfectly tuned to your goals, the end result is a warm inviting space that doesn’t distract, but guides you into the relaxation of sauna.
