FAQ Infrared Sauna

What is Infrared?

Sunlight is a combination of visible and invisible light. Infrared (IR) light is the part of the electromagnetic (EM) spectrum, that people encounter most in everyday life, although much of it goes unnoticed. It is invisible to human eyes, but people can feel it as heat.

IR radiation is one of the three ways heat is transferred from one place to another, the other two being convection and conduction. Everything with a temperature above about - 450 degrees ºF or - 268 ºC emits IR radiation.

The infrared is divided into 3 segments by wavelengths (measured in microns):

  • Near infrared: 0.76~1.5 microns;
  • Middle infrared: 1.5~5.6 microns;
  • Far infrared: 5.6~1000 microns.

Among these segments, only far infrared penetrates organic substances such as the human body two to three inches so that the warming effect is very uniform.

Far infrared (FIR) is a region in the infrared spectrum of electromagnetic radiation, often defined as any radiation with a wavelength of 15 micrometers (µm) to 1 mm (corresponding to a range of about 20 THz to 300 GHz). All objects give off and receive infrared heat; the human body gives off and receives infrared heat
in the far infrared band.

Is far infrared heat safe?

Infrared heat is completely safe and all objects give off and receive infrared heat. In fact, it is so safe, hospitals use similar heaters to warm newborns. Infrared is a part of nature and essential for life.

The human body gives off and receives infrared in the far infrared band. When a mother rubs a babies stomach to relieve pain, it is the infrared heat from her hand that is causing the healing effect. We have tuned our True Wave heaters to give off far infrared in this same range for maximum absorption by your body and for maximum therapeutic benefits.

How does an infrared sauna work?

The idea behind infrared therapy is to heat your body directly with far infrared heat. In a traditional sauna you are just sitting in a hot room – 180-220 degrees. In an infrared sauna, the heat is heating your body directly and only 20% of the heat is heating the air. You want to heat your body core, meaning your front core and your back core. Your body absorbs the infrared heat and reacts to it.

The infrared heat raises your core body temperature and stimulates your lymphatic system, immune system and your cardiovascular system. Your body's response to that is to sweat profusely. Once sweating, the water in our body also resonate with far infrared heat and this helps with the detoxification process.

For that reason, both front and back wall heaters are very important in an infrared sauna. If you do not have front heaters in your sauna, you will not raise your core body temperature as well and you will not receive as much of the desired effect.

What is the optimum infrared frequency for an infrared sauna?

The infrared frequency of any infrared heater is determined by the surface temperature of the heater itself. The lower the surface temperature of the heater, the longer the infrared wave and the more beneficial the infrared heat will be.

What is the best wood used in an infrared sauna?

The traditional sauna for thousands of years has been made predominately from close grain cedar for many obvious reasons:

  • Cedarwood is soft wood that resists the cracking and splitting caused by the heating up and cooling down in the sauna. No sauna wood lasts longer than cedarwood.
  • Cedarwood contains aromatic oils that are known for their healing and cleansing properties to aid detoxification during the sauna. Cedarwood can also help disperse excess fluids throughout the body.
  • Cedarwood is naturally anti-fungal and anti-bacterial owing to the unique properties of the cedar oil. This is especially important in the sauna where bodies, moisture and heat combine to make the environment perfect for molds and bacteria.
  • Cedarwood can be easily sanded inside the sauna to remove any stains caused by perspiration and to bring back the fresh cedar smell.
  • Cedar is non-toxic according to the Regulatory Information for Cedar from the Environmental Protection Agency(EPA) and World Health Organization(WHO). 

Why using infrared technology?

Because, infrared technology tunes the energy output so closely to the body’s own radiant energy, so that our bodies absorb as much as 93% of the far infrared waves that reach our skin and penetrate deep below it, producing a gentle warming inside the body.

The temperature inside an infrared sauna is adjustable and averages a comfortable 100 °F to 140 °F. This allows a person to sweat faster and to tolerate a longer period of time inside the sauna, allowing for the therapeutic effects to occur. Typical sessions in an infrared sauna last 20 to 45 minutes and can be repeated once or twice during the day to maximize the benefits.
