What is Red Light Therapy?

Red light therapy EU is a relatively new treatment option that has been gaining rapid popularity. Upon first hearing about the approach to light treatment, you are probably plagued with a wide variety of questions. With so many scientific terms and hard-to-pronounce words such as ‘Photobiomodulation,’ you’re likely scratching your head.

Don’t worry. We’ve got you covered in this deep dive into red light therapy. We’ll cover exactly what red light therapy is, the science of how it works, and who can benefit from it.

How Do You Define Red Light Therapy?

So, what is red light therapy? It’s a process in which red and near-infrared light is applied to various parts of the body. It is an entirely safe, painless, and natural treatment for a wide variety of ailments and physiological concerns.

It’s also generally referred to as low-level laser therapy (LLLT) and photobiomodulation therapy. Despite the differences in names, each of these therapy treatment options are very closely linked to one another.

Red light therapy involves using a tool that emits these wavelengths with particular LED light bulbs. These specially created light instruments can range in size from handheld to large enough to emit light that would cover your entire body. Depending upon what part of the body needs treatment, various red light therapy tools are available. The variety of tools available means that devices can target the patient’s specific needs and provide the best results possible.

This treatment process was first discovered in 1967 by Endre Mester at the Semmelweis University in Budapest, Hungary. Mester had pondered if lasers could cause cancer. To his surprise, his results yielded a shocking discovery that later became known as “laser biostimulation.” Mester had conducted a study on two groups of shaved rats, one of which he exposed to lower-powered red light. In the group exposed to the laser, not only did they not get cancer, but their fur actually grew back faster.

What are the benefits?

Since its initial use, red light therapy before and after physical activity has been an increasingly popular treatment, primarily due to its quick and painless results. In order to better understand why this treatment has become so popular, here are some of the many red light therapy benefits:

 

Stimulates healing for quicker, faster recovery
Aids in pain reduction
Helps with neurological issues such as Alzheimer’s and Parkinson’s
Elevates mood and sense of well-being
Boosts the immune system response
Helps with signs of skin tissue aging

The science that supports the technology used for therapy

With such a vast and diverse range of benefits, red light therapy has seen massive increases in the number of scientific studies to understand better how and why it works so well. As of today, there have been over ten thousand scientific studies completed.

With their research, there is a mountain of evidence to support their claims. To better understand why red light therapy works, we’ll further dive into how low light therapy works and how cells respond when provided with this therapy.

How does Red Light Therapy work?

Red light therapy is also commonly referred to as low-level light therapy (LLLT). Both photobiomodulation therapies utilize the science of red light but in slightly different ways. One uses LED lights, and the other uses lasers. To understand the difference, consider this, the Sun emits light at all frequencies. LED lights emit the same wavelength of colour but in a non-coherent way. Laser lights emit only one wavelength of light in a coherent way.

Red light therapy is commonly associated with therapy techniques that utilize LED lights affixed to a device. For any therapy to be considered LLLT, it must use only laser lights. These laser lights only emit between 600 and 1000nm and are less powerful than surgical lasers. Neither the red light therapy LED lights nor the LLLT lasers will generate heat.

A red light therapy device is specially outfitted with LED light bulbs that emit only specific bands of wavelengths. These LED lights only produce red and near-infrared wavelengths. The wavelengths these devices emit are measured in nanometers (nm). They can range from 620 to 660nm for visible red light and 810-850nm for near-infrared light.

The higher wavelength light bulbs are more typically used in offices for their ability to deliver more therapeutic results. It is imperative that only specific wavelengths of light can be emitted from these devices. This ensures that the laser lights are non-invasive and completely safe to use.

The lack of heat generated by both the LED red light therapy devices and LLLT lasers means cells do not increase in temperature. In addition, no adverse side effects have been discovered from utilizing this therapy. Red light therapy is very safe for patients seeking treatment.

What happens to the body when exposed to light therapy?

When effective treatment is used, the body’s cells will improve their metabolism and experience a reduction of inflammation. Cells in the body respond to light therapy via a photochemical response. When red and infrared light is applied to a treatment sight, the light will increase cellular adenosine triphosphate or ATP in that area. ATP is made in the cell’s mitochondria. You may remember from biology class, “The mitochondria is the powerhouse of the cell!”

When our cells are stressed out, our ATP does not work as well as it should. Nitric oxide molecules will bond to the ATP, and as a result, our cells do not perform as well. As light is penetrated into the cell’s mitochondria, the nitric oxide molecules that are inhibiting the ATP will detach from the ATP and instead bind to oxygen molecules. As a result, the mitochondria and ATP resume working effectively.

When the nitric oxide molecules pass out of the cells, they behave like a vasodilator. Blood flow is then encouraged to the treatment site and surrounding areas. As this happens, the communication between the cell’s nucleus and the rest of its parts begins to signal at optimal rates.

Photochemical reactions within cells somewhat resemble the photosynthesis of plants. Photochemical responses at the cellular level aid cells in working at their total capacity. As a result, this increases the cell’s energy. The result of increased blood flow to the area allows for inflammation and pain to be reduced.

Who can experience the benefits of using Red Light Therapy?

Red light therapy can benefit everyone as a pain-free solution to a myriad of health ailments and mood conditions. It is ideal for anyone looking to reduce pain and inflammation and increase their body’s ability to heal itself. Red Light therapy is also a fantastic choice for people who are seeking treatment outside of pharmaceuticals or surgery options. You can even undergo red light therapy before and after physical activity to maximise its benefits.

While the following list does not include all the individual categories of people who have seen the benefits of red light therapy, this list does boast some of the patient groups that have all seen success and health benefits after starting this type of treatment.

Conclusion

Red Light therapy is supported by science and has thousands of scientific research studies to support its claims. As a non-invasive treatment, it is an ideal option for anyone looking to better their health. From chronic inflammation to mood disorders, red light therapy can help benefit everyone. With targeted treatments available, you can expect to see results quickly.

LLLT works by increasing cellular regeneration and improving the cell’s ability to function. These improvements allow for various improvements in health and wellness. With no downtime associated with treatment, it is an easy way to better your overall health and wellness. If you’re looking for a science-supported treatment option that does not require invasive surgery or pharmaceutical medicines, then red light therapy is the solution you are seeking.
