BW Mobile & Home Saunas
Quality That Stands Alone
The foundation of our saunas is a strong 2×4 frame, exterior OSB, Tyvek, and all-weather metal siding. Next, we use insulation on all walls, including the floor if elevated. From there, we add an interior metal heat shield, cedar or pine spacers to prevent moisture traps, and the finished cedar. What’s the result? A professional-grade sauna designed to look exceptional and last a lifetime.

It depends on what you are searching for! If you want to rest, 15 to 30 minutes is plenty of time. If you want to cleanse and enhance your skin, 15 to 20 minutes is perfect. If you’re an athlete, resting for 15 to 20 minutes after exercise can help minimize muscular pain and improve circulation.

Factors like weight, age, and exposure duration affect calorie burn in a sauna, with a 30-minute session potentially burning 100-300 calories. Harvard Health found that infrared saunas can burn up to 1.5 calories per minute, while the American Council on Exercise estimates 50-150 calories in a hot session.

- Listen to Your Body: If you feel uncomfortable, exit the sauna! It is better to prevent than to cure.
- Stay Hydrated: Drink water before, during, and after your sauna session to replace lost fluids.
- Session Duration: Two to three sessions per week, each lasting 15 to 20 minutes, is a decent start.
- Sauna Etiquette: Shower before entering, dress lightly or with a towel for comfort, and keep talking to a minimal for a peaceful atmosphere.

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.

While sauna baths are safe for most healthy people, anyone with certain diseases, such as fever, cardiac issues, or severe infections, should take extra care. 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.
