What is Light Therapy?
Light travels at a range of frequencies interacting with the physical world in different ways and each lightwave frequency manifests as a unique colour. If you’ve ever heard the phrase, “eat a rainbow” you might know that different coloured foods have specific nutrients and benefits to human and animal health. A similar principle applies to light therapy (sometimes known as phototherapy or chromotherapy).
Light therapy uses controlled light waves to treat different ailments and diseases. Each wavelength of light penetrates a specific depth of skin tissue and, hence different wavelengths of lights can be used to treat different conditions. The LED lights that are commonly used in this field are comprised of complex semiconductors, which convert electrical currents into incoherent narrow-spectrum light, allowing for a more intense colour, or lightwave frequency. The LED lights we use at Freedom Float have multiple colour settings so you can control the settings depending on what you want to achieve. You can also ask a team member to help you select your light therapy settings.
Historical accounts of Light Therapy
Specific colours were used to restore health among ancient cultures in Egypt, Greece, China and India. During those civilizations, the windows of healing rooms were covered with cloth or dyed red and blue to capture the healing qualities of colour.
In Denmark, 1892, Dr Niels Ryberg Finsen reported the successful use of red light to prevent scar formation from smallpox. He was honoured with a Nobel Prize in 1903 for his pioneering work with light therapy when he had successfully healed tubercular skin lesions with ultraviolet light. Nikola Tesla, another 18th-century inventor, electrical engineer, mechanical engineer, physicist, and futurist, made many discoveries around the healing effects of light and the colour spectrum. These include UV light for lifting mood, UV light phototherapy for skin diseases, UV light and ozone therapy for treating viral disease, and much more.
Colour therapy for health is gaining ground today as a result of the rising use of Light Emitting Diodes (LEDs) in Medicine. Medical research sponsored by NASA, using both Red and Near Infrared (NIR) LEDs, has expanded our awareness of, and use cases for colour therapy.
Light Therapy at Freedom Float Centre
Here at Freedom Float, we offer LED light therapy in both our Infrared Sauna and in all of our Float Tanks. You can control the light depending on what colour, or lightwave frequency you are most in need of. Here is a guide to some of the options we have in the Float Tanks* and in the Infrared Sauna**:
Ideal number of treatments for Light Therapy effectiveness
According to Esthetician Edu, LED light therapy typically takes 20 minutes for a session to be visibly effective, and it takes 8-10 treatments to achieve desired results. At Freedom Float, our Infrared Sauna sessions are 30 – 45 minutes and our float sessions last for 1 hour so it’s up to you whether you choose to use one colour or alternate between colours throughout your session. One question that comes up occasionally is whether you can have too much exposure. Side effects from LED light therapy are rare and were not noted during clinical trials, however, having the LED bulbs too close to your eyes can cause sensitivity and can even be damaging if directly stared at for too long from a very close distance. In saying that, both infrared and LED therapies have significant bodies of evidence backing their efficacy and can also treat a variety of eye, neurological, and psychiatric disorders if used correctly. Light therapy has also been used for treating various types of cancer by slowing the rapid division of cancer cells and in some instances, increases the effectiveness of chemotherapy.
