I devote quite some time to reading the science of using light therapy, and I must say something. More than 7,000 light therapy studies have been conducted with most of them being related to studying red light with infrared being the second closest. Both lasers and LEDs are used as light therapy. Years ago, the idea of LEDs having a weakness was proved wrong. That caused a light therapy consumer explosion.
The reason why LEDs turn out to be as effective as lasers is because by the time the photons are in the body, there is a biological distinction made between an LED photon and a laser photon. The columnar nature of the laser light becomes out of the equation as the laser light strikes against the skin since the skin is significantly more reflective than it was presumed to be.
Low powered laser or LED light therapy is known as cold laser therapy or low level light or laser therapy when you perform it. The term employed in science is photobiomodulation i.e. the manipulation of the biology with the use of light. The red light therapy typically incorporates infrared light and the majority of personal products are a mixture of red and infrared. The color red is beneficial to the skin, pain, arthritis and hair growth.
The infrared penetrates further into the body than red. Infra-red is helpful in pain, arthritis, inflammation, treatment of poorly healed fractures, brain modulation. Blue can be used particularly to decrease the acne symptoms. It is assumed that it kills the P. acnes bacteria in an entirely non-invasive way and in no side effects because it is close to the UV wavelengths. That is given that the individual is using goggles because blue light not only causes injury to the eyes but alsohibits the manufacturing of melatonin.
The wavelengths 810 nm and 1070 nm are reasonably the strongest ones in the sense that they penetrate the deepest into the body. The 810 nm and 1070 nm are mostly used to conduct successful brain studies. The most interesting modality in red light therapy is the application of either 810n m or 1070 nm together with 10 Hz or 40 Hz pulse. Subjects affected by dementia, traumatic brain injury and Parkinson experience marked gains when the therapy is done in these parameters.
The deepest penetration into the brain is produced by the infrared wavelengths. The brain waves are entrained to 10 hz or 40 Hz which is alpha (rest) and gamma (alert). The best-selling red light application is the devices like light domes and face masks which have anti-aging impact. These normally provide red and infrared lighting, can also be obtained with blue and yellow light. The combination of blue and red is most suitable towards acne symptoms.
The blue kills the microbes and the red, ironically decreases redness. Both of them alone can help lower bumps and lesions. Scars can be minimized with the help of red and infrared. Yellow is a red reducer also. The combination of red and infrared is ideal in the synthesis of collagen and elastin hence chasing away wrinkles. Dosing is the greatest ordeal to the red light buyer.
Effective therapy demands that the energy amount (fluence) and wavelength should be within therapeutic window. The product description being done by marketing and non-medical individuals has the potential of making the market to become very confusing to the buyer. The manufacturers battle against each other to get rid of all the lights and so today every lamp on Amazon is supposedly 100 mW/cm2 irradiance at a fixed distance on the skin with the device. Others say 200 mW. The customer cannot be able to detect whether these values are correct.
This is an enormous task that the industry must rectify, since the overdose of right wavelength does not result to healthy transformation. The interaction of the mitochondria with the correct amount of the photons enables the body to initiate a chain reaction of ATP generation under the absorbed photon energy.
Yep. We are like plants.
Transformation of light with distance and time changed drastically. The customer will not improve in case he/she wrongs in the distance used or the duration used during the treatment per session.
The curing begins at a point where the wavelength absorbed is at the critical mass. A continuation of healing persists with the entry of photons. When the bag becomes full, healing is over. When the light is left on the same area, healing reverses in such a way that the therapy was not applied. The consumer must therefore use good suppliers who does test their lights with the correct equipment. I wish this clarifies some misconceptions regarding red light therapy. I am a little obsessed with the topic, so don not hesitate to ask me questions. Thanks fo reading. PEACE
