Historical Basis of Infrared Sauna and Red Light Therapy
Historically, both techniques have individual value and their origins vary.
Origin of Infrared Saunas
Dating back thousands of years, relating to the Greeks, Romans, and Native Americans, saunas have been popular among cultures. Since the advent of Infrared radiation in 1800, this concept has been in talks.
But it did not materialize, till a Japanese Doctor in 165 received his primary patient to build a ceramic Infrared sauna. In 1979, the very first full-spectrum infrared sauna for the public was available. Evolved over the years, these have been used for holistic health-related practices.
With time, many procedures such as chromotherapy, halotherapy are included to add more health benefits to the individual. Used in a wide variety of areas, this treatment is applied in medicine, dentistry autoimmune disorders.
Emergence of Red Light Therapy
Historically speaking, the use of natural light to cure ailments is called Hilo-therapy. Natural light therapy has been used for decades upon decades to treat several health issues. Hungarian physician Endre Mester in the 1960s conducted experiments with red light on mice.
This resulted in showing wound healing effectively. However, with time and the advent of the use of UV light, Danish physician, Dr.Finsen in 1893 received a Nobel Prize in this regard. He was awarded this because of his work in treating smallpox scars with red light.
Much later, in 2020, studies revealed that LED phototherapy using red light can have anti-aging effects. Due to their health benefits, they are commonly used in clinics and wellness centers. The red light therapy machines that are used to perform these procedures have become more portable over time.
Operating Principles and Working of Infrared Saunas
Infrared saunas function on the basis of employing infrared radiation to heat the body straight away. They work by inducing thermal stress on, the body. This is essential for their operation. Infrared heating systems, developed specifically for use in saunas, generate mild electromagnetic waves that are safe for human skin. Up to 3 centimeters (1.18 inches), infrared radiation may go through the human body.
These go under the epidermis to warm the inside of the body. Infrared saunas are preferable because they warm the body rather than the air, which may be uncomfortable and inefficient. Most saunas use ceramic or carbon heaters positioned around the area. Infrared radiation, which these heaters produce, may be absorbed by the body and used therapeutically in a number of ways.
The Science Behind Red Light Therapy and Its Mechanism
Among the many types of Photobiomodulation, red light treatment is one. Light-emitting diodes (LEDs) are used to boost cell turnover for medical use. The wavelengths of light utilized in Red Light Therapy (RLT) fall into the Infrared (IR; 600-700 nm) and Near Infrared (NIR; 780-1100 nm) spectrum.
Mitochondria, the "power plant" in the body cells, are considered to be the focus of red light treatment. Extra energy allows various cells to perform their functions more effectively. Although visible light has certain useful ranges, its poor penetration of about 1-3 mm is a significant limitation.
Clinical trials have shown that NIR light wavelengths can get farther than visible light. During treatment, radiation is used to transport electrons all over the body. In addition to relieving pain, it repairs cell damage and solves other issues that stem from them. High-quality red light therapy panels such as Smibea’s SM-W200-T from Bonliter with 750W LED power can be employed for commercial use.
