10 benefits of the red light therapy and near infrared therapy

It has been known for some time now that exposing yourself to the sun is the most natural and beneficial way to stay healthy. When you receive natural light, you are exposed to different wavelengths that penetrate the skin at various levels, exerting many therapeutic effects. Among these wavelengths, those of red light (600-700 nanometers) are able to reach deeper cells and tissues, giving a cascade of positive effects.

Red and near infrared wavelengths work on cellular metabolism and it is scientifically documented how, with the exposure of cells to this light increases energy production (ATP), oxygenation of cells, blood circulation in the body and the release of carbon dioxide production. But they also participate in the reduction in stress hormones, lactic acid, inflammation and free radicals. 

It goes without saying that, with all these benefits, it would be a good idea to receive red and infrared light every day by exposing yourself to the sun bare-chested for 20 minutes at dawn and dusk (hours irradiated by these orange colors). It might be easy now, during the summer, but nourishing the body with these wavelengths consistently all year round is a challenge.

It is for this reason that red and infrared light therapy machines were invented to give the light support you need. More than 50,000 scientific studies demonstrate how red light therapy and infrared light therapy is a regenerative and energetic therapy The overall well-being of the organism comes from the body’s ability to regenerate, repair itself, detoxify and increase the immune defenses. To carry out these functions, the body needs energy. Therefore, light therapy, by stimulating greater production of ATP in the cells, guarantees the energy necessary for each metabolic process to work correctly and allows the body to regenerate.

Among the countless benefits that can be achieved with red and infrared light therapy, these are the top 10 scientifically proven:

1. Treatment of arthritis

Light therapy is a great help in reducing pain and inflammation. One of the authorities on red light therapy, Dr. Michael R. Hamblin of Harvard University (Department of Dermatology) confirmed that even a single application of near-infrared (810nm) laser therapy reduces inflammation with a duration of 24 hours.

2. Support for hair growth 

Red light therapy is used extensively to stimulate hair growth. It must be constant, however, and contain the wavelength 630 nm. One study observed that light stimulates stem cells in the hair follicle, encouraging the hair follicle into an anagen, or growth phase.

3. Pain treatment

Red and infrared can relieve pain. Scientific reviews carried out in various fields demonstrate how the use of light therapy is beneficial for re-modulating the inflammation of inflammatory processes. It is also useful in treating acute pain in a short period and can immediately reduce pain in neck pain and neck pain.

4. Collagen stimulation

Light has been shown to be useful for treating skin disorders. The red wavelengths are able to penetrate the epidermis both in the superficial and deeper layers of the dermis. Right here reside collagen, elastin and other essential proteins, responsible for the beauty of the skin. By stimulating the production of elastin and collagen, anti-aging benefits can be achieved.

5. Reduction of anxiety and depression

It is well known that light has a very positive effect on our emotions and psycho-emotional well-being. Just think of the effects of a holiday in the sun, the well-being then lasts for days. Even single light therapy treatments have an anti-depressant effect that lasts for days at a time.

6. Increased brain function

The University of Texas has shown that transcranial laser stimulation increases brain function. Those who underwent treatment of this type experienced a cognitive and emotional increase. Given the results, according to the researchers, light therapy is the most powerful neurotropic substance.

7. Increased testosterone

Many studies have shown that light causes more testosterone to be produced where there is a deficiency. A study, carried out by the University of Siena and presented in Vienna at the congress of the European College of Neuropsychopharmacology, has proven how sexual desire varies according to the seasons and the variation in intensity of natural light. In fact, in winter, the increase in melatonin inhibits the synthesis of testosterone, while in summer, when melatonin decreases, testosterone increases. This shows how light has an effect not only on our mood, but also on our desire.

8. Increased bone density

Perhaps one of the best-known effects of exposure to light is its beneficial role in bone calcification, but this benefit is often associated with vitamin D and blue and ultraviolet light. In fact, red and infrared therapy also helps bone density. In fact, studies on ultra-low level laser and infrared confirm how their use accelerates bone repair time and osteoclasts in new bone formation. The therapy can make bones grow stronger and more resistant because it penetrates the tissues near the bones more deeply.

9. Acceleration in tissue healing

A review of 68 studies from three Brazilian universities observed that wavelengths, between 632 and 830nm, accelerate the repair of wounds and scars by shortening post-surgery healing times, as well as injury times. Laser light has been used in surgery for years to promote post-operative comfort more quickly.

10. Support for lipid metabolism

In 2015, a group of researchers from the University of Sao Paolo carried out a randomized double-blind study studying the effects of near-infrared light (808nm) on 64 overweight women, divided into two groups. After 20 weeks, the group that exercised three times a week and received light therapy doubled the amount of fat lost compared to the movement-only group. The study concluded that the group that did light therapy also had an increase/strengthening of muscle mass and strengthening of muscles close to the musculoskeletal system.

It is worth underlining that all this research has shown that light therapy has no side effects; it is therefore a healthy and safe treatment. However, for it to work there must be some ideal conditions. These are: the treatment space, selecting the right body part, the right type of light and distance, and the session frequency and duration.
