Infrared heat primarily warms only objects in its direct path and has a lesser effect on temperature of the surrounding air.
To understand how infrared heat works, picture yourself outdoors on a summer day with the sun beaming overhead. Your body feels warm from the sun and you become hot. Then a cloud passes overhead, blocking out the sun. The temperature outside has not changed, but you feel cooler in the shade. The Sun’s infrared rays were heating your body.
Infrared heaters warm the body in the same manner as natural sunlight. Infrared emitters in the sauna mimic and intensify this effect. All life requires heat from the sun.
FAR Infrared heat is not ultraviolet radiation but a narrow band of energy within the 5.6 to 15 micron (µ) level. This type of energy travels only 2-3″ deep into the body to increase circulation and nourish damaged tissue.
The sun is the primary source of radiant energy, but not all of this energy is beneficial. Sunlight also contains harmful solar radiation. Although life needs energy from the sun, too much sunlight damages the skin.
Infrared heat provides all the healthy benefits of natural sunlight without any of the dangerous effects of solar radiation. FAR Infrared heat therapy uses the wavelength of the visible and non-visible light spectrum of sunlight that heats the body normally.
Infrared, the healthy part of sunlight
Sunlight is part of a wide spectrum of frequencies, including ultraviolet and infrared rays. Visible sunlight is in the middle of this spectrum.
At a higher frequency, visible light changes to ultraviolet rays that can cause sunburn. At a lower frequency, however, sunlight changes to gentle infrared rays. It is these rays that allow the sun to warm you, even on a cold winter’s day.
The Saunafin frequencies:
Within this wide spread of frequencies the 5.6 – 15 micron range is the most therapeutic to the human body. Split evenly between the 9.4µ pivot point of peak human output. Only Solid Ceramic Infrared Emitters like the ones used by Saunafin operate within the FAR Infrared range. Saunafin Infrared elements are designed to operate within this range to maximize the effectiveness of your therapy.
Infrared means deep heat:
Because infrared penetrates safely and comfortably up to 3 inches inside your body, even your deep tissues and organs are stimulated, meaning you perspire. Hard to reach impurities are eliminated through your skin using lower, comfortable temperatures.
Increases blood circulation and strengthens your cardiovascular system:
As your body increases sweat production to cool itself, your heart works harder pumping more blood, achieving the conditioning benefits of continuous exercise. By widening your blood vessels and enriching your blood with oxygen you feel more energetic and your skin gets a beautiful, youthful glow.
“Regular use of a sauna may impact a similar stress on the cardiovascular system as running, and its regular use may be as effective [at] burning calories.” – Journal of the American Medical Association.
Infrared, ideal for detoxification
Dr. Toshiko Yamazaki, M.D. owns a clinic in Japan where she has done extensive research on the therapeutic uses of far infrared. In her book, The Science of Far-Infrared Therapies, she explains that one of the reasons FIR (Far-Infrared) has beneficial results in a variety of illnesses is the ability of FIR waves to remove toxins, which are often at the core of many health problems.
