Infrared saunas utilize light to produce heat, a unique feature that makes them different from traditional saunas that heat the surrounding air. This method heats your body directly, allowing better penetration into your skin and providing various health benefits. The infrared light waves produced by these saunas create heat within the body, causing you to sweat and release accumulated toxins. The heat generated by an infrared sauna can increase your core body temperature, leading to a rise in heart rate — similar to what you experience during physical exercise. As your body works harder to cool down or maintain an elevated heart rate, it burns extra calories, potentially improving cardiovascular health. Moreover, the deep-reaching heat of infrared can stimulate the lymphatic system, enhance blood circulation, and oxygenate your cells, facilitating cellular repair and regeneration, thus contributing to overall health and wellness.

  • Detoxification: The process of sweating, a natural mechanism of the body to eliminate toxins, is critical for detoxification and is encouraged by infrared saunas.
  • Relaxation: Infrared sauna therapy aids in relaxation by balancing cortisol levels, which is the primary stress hormone in your body.
  • Pain Relief: The deep penetration of infrared heat into tissues, joints, and muscles can alleviate minor to major aches and chronic pain conditions.
  • Improved Circulation: Regular usage of infrared saunas, particularly at the middle-infrared level, can promote blood flow, enhance muscle recovery, and reduce pain and inflammation post-strenuous exercise.
  • Skin Purification: Infrared sauna technology can purify your skin by eliminating toxins from your pores and boosting circulation, leading to clearer, softer, and healthier skin.

Don't Take Our Word For it! Here's What Our Customers Think:

Hats off to Homestead Supplier for superior customer service - these guys go above and beyond to answer all my questions. We purchased the Beach House shed for some extra storage but ended up using it as a backyard playhouse for the kids :). Now we have to buy another shed lol... The shed is great, sturdy, and would recommend to others.

- Sam B.

I found the buying experience to be far better than expected. Very easy to order, received immediate order confirmation, excellent customer service, order showed earlier than expected and in excellent condition. Would definitely recommend

- Dean G.

After 7 months of waiting for our pool to be completed, we are thrilled to have gotten our new shed built. It perfectly completes our backyard renovation. We love it! The instructions were clear, and the building is sturdy. We’ve had a number of inquiries about who we bought our shed kit from.

- Karen E.
