frequently asked questions

Contact us if you can't find an answer below.

What are the benefits of using a sauna?

Exposure to heat helps to relax the muscles and relieve stress and tension. Studies show that heat dilates blood vessels, improving blood flow and reducing blood pressure. The perspiration induced by the sauna helps to eliminate toxins from the body. In addition, research indicates that regular sauna use can strengthen the immune system by increasing the production of white blood cells, improve cardiovascular health and reduce the risk of heart disease. Using the sauna at night also makes it easier to fall asleep. The general feeling of well-being after the sauna is often attributed to the release of endorphins.

What are the benefits of using a spa?

Immersion in hot water relaxes the muscles and reduces pressure on the joints, making it particularly beneficial for people with arthritis or muscle pain. In addition, the water jets provide a deep tissue massage, which can improve circulation and speed up muscle recovery after intense exercise. Studies show that immersion in hot water can reduce levels of cortisol, the stress hormone, promoting relaxation and improving sleep quality. Like saunas, spas also improve cardiovascular health, especially in people with high blood pressure, creating an ideal environment for mental relaxation and stress relief.

What are the benefits of using a cold plunge?

Cold plunging, or immersion in cold water, has a solid scientific basis for its benefits. Exposure to cold water reduces inflammation by constricting blood vessels and lowering tissue temperature, making it excellent for post-exercise recovery. Studies suggest that regular cold plunges can help reduce the perception of pain and decrease muscle fatigue. In addition, cold activates the sympathetic nervous system, increasing the production of norepinephrine, a hormone associated with greater concentration and alertness. Immersion in cold water also stimulates the metabolism and can improve mood due to the release of endorphins and a reduction in cortisol levels. In general, cold plunges provide a feeling of revitalization and mental clarity, while supporting muscle recovery."

Modifications to the rear wall

Wood treatment

Recommended annual coating:

For all types of wood, we recommend an annual protective coating, with the first application carried out during or immediately after installation. If you wish, Saunamo can handle the entire treatment process for both exterior and interior wood.

Exterior treatment:

We use Tikkurila primer oil and Valtti Color Plus wood varnish to obtain the best protection against moisture, exposure to UV rays, insects, mold, rot and deterioration. The annual application of Valtti Color Plus wood varnish is highly recommended to ensure long-lasting durability and resistance to the elements. This exterior treatment is essential for maintaining the integrity of the wood over time.

Interior treatment:

For interior wooden surfaces, we apply Tikkurila's Sauna Wax and Sauna Floor Oil to increase durability against dirt and mold. Although interior treatment is optional, it is strongly recommended to preserve the quality of the wood and maintain a clean, protected finish.
