Red Light Therapy: History, Benefits & Process

Red Light Therapy (RLT) is now a very well-recognized natural health procedure. From professional athletes to movie-stars and celebrities to major skin care professionals, top fitness trainers and more, everyone uses Red Light Therapy to boost their immune system, enhance their health, reduce aging symptoms and much more.

However how did red light therapy come into existence? And how did it become such a widespread, non-invasive and all-natural treatment method? We will answer here these questions and provide a practical timeline of the history as well as the main benefits and process behind it.

The Origins of Red Light Therapy

The History of Modern LED Therapy began in 1903 when a scientist named Niels Finsen earned a Nobel Prize in Medicine for developing the use of light therapy, formerly known as photobiomulation or low level laser therapy.

Solar therapy has been used for a long time by the Egyptians and the Inca and other types of light therapy were also utilized in ancient Greece, China, and India to cure all sorts of illnesses.

#1 FUN FACT: During Medieval Times in England, when Leprosy was a common disease, patients were required to sit in a room that is exposed to the sun where monks would place a red cloth onto a patient face and making him absorb all the energy from sunlights thus slowing down the infection procedure.

Since then, modern Light Therapy is now referred to as Red Light Therapy (or RLT)

And started to become widely used to relieve chronic pain, arthritis and related conditions, joint rehabilitation and soft tissue damages, as well as other medical disorders in Eastern Europe during the 1960s as research progressed. 

During that period, Red Light Therapy was also being applied in a minor part of the U.S. to equestrian activities for animals that suffered from joint and soft tissue damages.

By the 1980s, the field, while still very current, grew exponentially and more and more clinics and medical science industries took advantage of the effects provided by Light Therapy.

Extensive studies and years of use of red light therapy and infrared light therapy demonstrated that the deep tissues not only recovered, but that skin and cosmetic conditions significantly improved as well.

Additionally, numerous professional sports teams as well as athletes discovered that Red Light Therapy has the potential to treat sports-related injuries, and physiotherapists reported a recovery time 50 times quicker than without this therapy.

#2 FUN FACT: In order to figure out how to grow plants and feed astronauts in space, the NASA sought the expertise of plant biologists who turned to LED lights to come up with the solutions. After LEDs proved to be an efficient way to grow plants, NASA investigated the use of LED therapy for tissue healing also finding a number of beneficial results. Since then, LEDs were developed into innovative and powerful lights which are now being used in a wide array of aesthetic treatments.

 

Main Benefits of Red Light Therapy

Light therapy demonstrated in more than 30 years of independent study to deliver powerful, benefits for living cells. The visible red light, at a wavelength of 650 nm & 850 nm (nanometres), is absorbed into the deep tissues up to 8 to 10 mm deep.

An expanding list of applications is proven with red light therapy and with it comes an ever growing list of beneficial effects of the use of this therapy compared to the prescribed drugs.

A few highlights of what we believe to be the major health advantages of light therapy can include the following:

- It is a completely naturally occurring process. You are using the wavelengths of natural light to treat your particular health condition.

- The therapy does not involve any drugs. Which is not a bad thing, since you don't have the likelihood of developing an addiction to a prescription drugs, like many people have done over the years. With current pharmaceutical costs, red light treatment is therefore much cheaper.

- There are no toxic substances. Certain prescribed drugs often contain harmful chemicals which can have an adverse effect on your body or body functions. Red light therapy does not involve any chemicals anywhere in the treatment.

- Since this treatment consists mainly of lighting an injured area, it can easily be performed within the comfort of your home. However, before you decide to go out and get your red light back, make sure you have reviewed all the risks associated with this therapy.

- The therapy does not provoke any inconvenience. No itching, burning, pain or tingling is known to occur from red light therapy, unlike other forms of treatments.

- While more research is being conducted on red light therapy at the present time, no short- or long-term effects have been observed in people who have followed this treatment.

- It's not invasive. Luminotherapy, for the most part, is a transcutaneous and non-invasive treatment.

- It will not take over your life and hold you back. Certain medications may prevent you to drive, leave the house, eat or drink certain things. But with Light Therapy, it is possible for you to do whatever you want to do and when you want to do it, all with no side effects.Clinically Proven Benefits Light Therapy

Simultaneously, a compound known as nitric oxide is emitted, favoring blood circulation and expansion which is essential component for our well-being.

What's so special about nitric oxide?

Nitric oxide is a substance which plays a role in numerous functions in the body and in pathological events.

On top of being a powerful blood vessel widener (which can increase blood flow), It is also proven to support the functioning of the immune system and the wound healing process.

It is extremely useful as it is hard for bacteria to resist it.

In its vapor and gas state, nitric oxide is used to heal all sorts of infections.

How does Red Light Therapy work?

Red Light Therapy utilizes wavelengths of coloured visible spectrum that have specific beneficial effects on the skin. Due to aging, skin damages or traumas, our healthier skin cells are affected and unable to regenerate themselves independently.

Red Light Therapy Process

It is important to differentiate between the two types of lights used.

 Red Light 

Helps increase levels of natural hydration, reducing inflammation and redness, shrinking the look of the pores, regulating the production of excess oils, improving circulation, accelerating skin repairs as is an approved medical treatment for rosacea.

 Near Infrared Light 

It is the most profoundly absorbed wavelength, increases cell porosity and absorption, reduces lines and wrinkles, improving elasticity, reducing painfulness and inflammations, accelerating wound healing and curing diseases like acne.

As a result, a person may use the light as an energy source to fuel the repair and rejuvenate skin cells that have been damaged or, in the case of acne treatment, to eliminate bacterial growth. Such energy stimulates production of collagen and elasticity, stimulates circulation and speeds up tissue repair. While undergoing the procedure, all you need to do is lie down or even sit or stand under/in front of a light panel while the device does all the work.

Red Light Therapy Nanometers

This is what it looks like in action:

→ Light affects a group of cells at the cellular level.

→ Light causes these cells to release other cells known as cellular products.

→ These products have the effect of the dilation (opening) of capillary blood vessels in the skin.

→ The dilation of these blood vessels leads to an increase in the the blood flow.

→ An increase in blood flow carries oxygen and nutrients for the skin.

→ Light therapy restores the skin's natural appearance and promotes tissue regeneration.Skin Rejuvenation Red Light Therapy

LEDs are similar to lasers in that they can emit the same energy but they differ in the way the light energy is delivered.
Lasers are focused beams, at a single wavelength and their emitters can be intense enough to burn/cut fabric.

The LEDs do not deliver enough power to damage the skin but provide enough energy to stimulate the body's reaction to treat itself.

Apart from the big results, the best news is that Red Light Therapy hasn't had any reported side effects. This is an FDA-approved therapy.

Are there any side effects to Red Light Therapy?

There does not seem to be any significant risks or side effects. As a matter of fact, certain studies reported in the research documents that there is an " virtually total absence of side effects" linked to treatment with red light therapy.

Researchers have pointed out that it is " in general harmless to all types of skin, and even to pregnant women".

There are anecdotal reports of some people finding that red light therapy causes irritation or discomfort to their eyes, however, it is possible to remedy this by wearing tanning goggles.

Why are RedJuv lights your best bet? 

Whilst the wavelengths of red light influence the effectiveness of the treatments, many don't emphasize, that the energy efficiency of the red light therapy device also plays a major role in the effectiveness of the treatment. Currently, there is a HUGE difference among the red light therapy devices available at the moment. The majority of them emit alarmingly low levels of power intensity, even though they consume a lot of energy.

The RedJuv Therapy Lights were among the first red light therapy companies to bring the concept of power measurement to the market. 

The efficiency of an LED therapy light is called irradiance (the flow of emitted light energy by area unit) which is measured in mw/cm2. We have been helping to raise awareness of the differences between brands of LED lamps with respect to these efficiencies for many years.

RedJuv therapy lights maximize energy efficiency, ensuring you receive clinically proven red light therapy treatments. Our lamps emit more energy than any other LED lamps on the market today. Only RedJuv lamps offer more red light and near-infrared light absorption than that of any other light available.
