The Truth About Red Light Therapy | How It Works And What You Can Expect

Red Light Therapy

The photobiomodulation behind red and near-infrared light therapy has been much clearer than in decades past. In this blog, we’ll talk about how red and near-infrared light therapy works on our body and also recommend the best at home red light therapy devices for you. We will also talk about the potential medical applications of red light therapy and the effects it has on various parts of our body. So whether you’re looking to soothe inflammation or improve skin quality, red light therapy is worth a read!

How does red light therapy work on our bodies?

Briefly, what lies behind red light therapy is the photobiomodulation mechanism, which uses very low levels of irradiation to trigger the body’s response through the absorption of photons instead of light heat. It targets the function of the mitochondria to enhance cellular respiration. The most important photoreceptors in our bodies are water and cytochrome c oxidase (CCO). Both adenosine triphosphate (ATP) production and oxygen consumption by cells can be increased, which leads to the release of nitric oxide (NO) and activates secondary signaling pathways, including the improvement of immune functions and many other transcription factors. It may be a little surprising at the beginning, but it is true that red and near-infrared light can be said to be therapeutic light energy for human bodies, which has been supported by numerous scientific studies. 

Mitochondria can be the core of an engine in the cells to drive a series of cellular functions, including the regulation of oxidative stress, calcium metabolism, apoptosis, and a host of signaling pathways. The number of mitochondria in cells varies widely, and it is strongly related to the metabolic requirements of the cell, ranging from a few to thousands. When applying light irradiation, mitochondria, as the initial sites of light absorption and containing the primary photoreceptor, i.e., CCO, trigger beneficial processes in a series of cells, such as osteoblasts, keratinocytes, fibroblasts, muscle cells, neural cells, and so forth. In this way, red and near infrared light therapy has the potential of healing a wide range of medical conditions or mitigating their symptoms. Furthermore, mitochondrial function and structure have been suggested in this study as agents of stem cell competence, including stem cells and induced pluripotent stem cells. The picture below demonstrated different structure types and number during the development of dynamics of mitochondrial morphology during reprogramming and differentiation. 

 Red Light Therapy

What is necessary to mention is the biphasic response of red light irradiation. Contemporary theories support the idea that the mitochondrial membrane potential (MMP) can decline back to the baseline and even be lowered below it after having reached a maximum at the optimum dose if excessive doses of light are applied, because the reservation of ATP within the cells begin to be depleted by the production of excessive reactive oxygen species (ROS), the release of excessive free NO, and the activation of a cytotoxic mitochondrial signaling pathway leading to apoptosis. 

What to expect from red light therapy

Red light therapy is a phototherapy treatment that uses red light to treat various disorders. The common benefits of red and near infrared light therapy that have been concretely proven by scientific research and that you can expect from it include: 

1) Red light therapy boosts circulation:

Good blood circulation can bring more benefits than you may think. It’s not just vital for healthy skin, but the detoxification function and support flow of oxygen and nutrients. Blood circulation dysfunction holds a key to treating a variety of diseases, such as alopecia, arthritis, pain relief, wound healing, and so on. 

2) Red light therapy for wound healing

Red light therapy can speed up the natural repair process, which has benefits for healing wounds, clearing up acne vulgaris, and so forth. 

3) Red light therapy for collagen production

Red light therapy can stimulate collagen and fibroblast proliferation, which has been long applied in numerous clinical trials of various types of skin rejuvenation. Through this property, red light therapy can also improve the skin’s complexion and feel. 

4) Red light therapy for inflammation reduction

Red light therapy can help with the suppression of pro-inflammatory cytokines and gene expression in nuclear transcription, which makes it an effective treatment for a lot of diseases of chronic inflammation, such as rosacea, psoriasis, arthritis, back pain, and other neuropathies. The anti-inflammatory function of red light therapy can also benefit pain relief, muscle repair and recovery, wound healing, and acne vulagris. 

5) Infrared light therapy for nervous system

The nerve cells are specially reactive with infrared light therapy, which also helps with mood conditions, seasonal affective disorder, neurodegenerative diseases, peripheral neuropathies, and so forth. 

Bestqool: The best at home red light therapy devices for you

Red light therapy is a popular treatment for a variety of health conditions. Home red light therapy devices offer convenience and control over the treatments. Choosing true medical-grade, professional red light therapy devices is undoubtedly important for desired therapeutic effects. That Bestqool is credited as the best option is not out of thin air but from the following reasons:

 Red Light Therapy

1) Long-enaged in the advanced LED manufacturing technology. 

One has to be clarified is that not every simple LED panel has therapeutic effect and what barriers the applications of LED light therapy before the success of NASA experiment is to control the range of emitting wavelengths. The LED manufacturing is in fact more sophisticated than you may expect. Only the sufficiently narrow band of target specific wavelengths with therapeutic effects can product desired effects. Bestqool is able to produce devices that focus on the most suggestive and effective wavelengths within the narrow band (red light at 660 nm and near-infrared light at 830 nm), which are based on numerous clinical trials. The irradiance levels and distribution pattern of LED light therapy devices are also critical for a successful treatment. Numerous studies have shown that the linear reciprocity of irradiance output and accumulated positive effect can just present from 1 to 100 mW/cm^2. The irradiance level out of this range can’t produce therapeutic effects mostly even if the treatment time is accumulated. Bestqool products are able to produce irradiance levels to reach medical-grade and optimal therapeutic effects. Using 10 minutes of Bestqool devices is just equal to 20 minutes of others. 

2) Investigation in the field of medical devices

As FDA Class II medical devices, all Bestqool products ensure the effectiveness and safety of therapy. The investigation in this medical field helps Bestqool produce more professional light therapy devices. For example, the unacceptable heating of human tissues is in fact dependent on the wavelength parameters, and the distribution of LED light beam profiles can also greatly affect the actural energy dose of cells at the peripheral spot and in the exact center of beams, as explained in this scientific research. 

3) Longest warranty in the market

All Bestqool products come with a three-year warranty, which is currently the longest in the market, to ensure the success of your light therapy. Bestqool highly values the real feedback from our clients and patients’ satisfaction and does our best for your health.
