What Are Infrared Saunas?

Infrared saunas are a type of sauna that use infrared light waves to create heat. Unlike traditional saunas, which heat the air around the user to induce sweating, infrared saunas directly warm the body. This direct heating method allows for deeper heat penetration at lower temperatures, making it a more comfortable experience for many users.

How Do Infrared Saunas Work?

Infrared saunas employ infrared heaters to emit infrared light, which is absorbed by the surface of the skin. This process promotes a more efficient and intense form of sweating at cellular levels, aiding in detoxification, relaxation, and potentially providing therapeutic benefits.

Traditional Saunas vs. Infrared Saunas

  • Temperature: Traditional saunas operate at higher temperatures ranging from 150°F to 185°F, while infrared saunas are effective at lower temperatures, typically between 120°F and 140°F.
  • Heating Method: Traditional saunas heat the air, which then warms the body. In contrast, infrared saunas directly heat the body without significantly warming the surrounding air.
  • Experience and Tolerance: Due to the lower temperatures and direct heat method, many find infrared saunas to be more tolerable and comfortable, especially for extended sessions.

Potential Health Benefits

Infrared saunas are lauded for a variety of potential health benefits, including improved circulation, muscle relaxation, detoxification through sweating, and support for the immune system. Some studies also suggest benefits related to pain relief, weight loss, skin health, and the potential to treat cancer, though more research is needed to fully understand these effects.
