Does Red Light Therapy / Red Light Therapy Work?

Light therapy 'or technically called photobiomodulation' is on the rise to become a popular form of therapy in the field of health. Many clinical studies have already proven this.

If you are reading this you have probably heard of red light therapy and its supposed natural health benefits. But does it really work? This article answers that question by examining the extensive basis of clinical research on red and shortwave infrared light therapy.

Photobiomodulation is a form of light therapy. Photobiomodulation promotes the self-healing capacity of human cells. This is done with the help of light with a specific wavelength and intensity. As soon as this light enters the cells, the mitochondria are activated. These are the energy suppliers of the cell. Activation of these mitochondria promotes the cell's self-healing ability. And those cellular changes, in turn, can lead to improving your health.

Light Therapy: Legitimate Medicine or Not?

NASA had that same question in the early 1990s and got to work. After they discovered that the red light therapy activated the natural growth of plants in space, they began to investigate medical applications for humans. NASA's findings showed health benefits with specific wavelengths of red light provided by light emitting diodes (LEDs).

Medical science has noticed this, and extensive clinical research has been conducted over the past three decades into the various medical applications of red light therapy. The results are extremely encouraging for those seeking natural, non-invasive treatments for a wide variety of medical conditions.

The impact of light is most recognizable in the form of pigment development due to UV from the sun or tanning bed. The fact that you can tan so quickly with light shows how sensitive the body is to these frequencies. Many women are also familiar with removing hair with IPL or Laser, so light is strong enough to remove hair under the right conditions. Other forms of light therapy such as UV-B light therapy have also been used in hospitals and clinics for decades.

How does LED Red Light Therapy work?

Natural red light nourishes the cells. A light therapy lamp such as a NorahLux delivers red and shortwave infrared wavelengths directly to your body with powerful LEDs. Emission concentrated by means of special lenses amplifies light. So strong that it contains a tremendous amount of energy. The positive effects of photobiomodulation are around 650nm and 850nm. The light of the leds cause photo-biochemical reactions in cells. The word 'photo' actually means light: (Gr. Φῶς, gen. Φωτός (phôs, phôtós) = light).These photons of natural therapeutic light produce a chemical reaction in your cells' mitochondria that stimulates energy production and regeneration.

Photobiomodulation is painless and should not be confused with 'High Level Laser Therapy'. The latter form of laser therapy uses heat to enter the body. And that can be painful in some cases. The light used for photobiomodulation is much weaker, but strong enough to reach the body cells. In the article 'How does Red Light Therapy work?'you can read a lot more about this.

LEDs make the difference

Highly efficient medical grade LEDs are by far the best way to deliver the specific wavelengths of light and intensity needed for optimal whole-body light therapy. LEDs are able to deliver a specific wavelength of light with high efficiency, with almost no heat. They last 25 times longer than incandescent bulbs and they are durable and unlikely to break. LEDs have revolutionized lighting over the past two decades and have made it possible for individuals to use safe, effective light therapy in their own homes at a reasonable cost.
NorahLux light therapy lamps use LEDs that deliver 3 watts each through a 30 degree (angle) lens. The frequencies of the lenses are 660nm and 850nm in order to meet the scientifically proven best effect of Red Light Therapy. As described above, the angle of the lens ensures that the light is bundled extra strongly so that the light is not lost before it hits your body.

A large 2013 study of light therapy conducted by researchers at Harvard and MIT praised light therapy for its

"non-invasive nature and almost complete absence of side effects."

The two main effects of Red Light Therapy are:

More ATP energy: light therapy reduces oxidative stress and increases adenosine triphosphate (ATP) production. Produced by cellular respiration, ATP is a crucial molecule that all living things need to make usable energy for your body. It is often referred to as "the energy molecule of life". This is cellular biochemical energy. ATP causes several positive physiological responses, such as an increase in cellular metabolism, which stimulates the body's self-healing ability.
This means, among other things, more energy and a general better health which are the basis for all other physical promotions.

Improved cell signaling: specific wavelengths of light help create a better oxidative environment in your cells. This results in the activation of numerous intracellular signaling pathways, increased protein synthesis, enzyme activation and improved cell cycle progression.

Health benefits of red and shortwave infrared light therapy

Thousands of peer-reviewed clinical studies and research on red light therapy have been conducted over the past 3 decades and published in major scientific journals. The evidence is overwhelming in favor of its effectiveness and safety, and the FDA has approved light therapy for the treatment of joint pain, wrinkle reduction, and many other conditions. [1,2,3,4,5,6]

Here is an overview of some of the most important, clinically proven health benefits of red light therapy:

Inflammation and joint pain

One of the main responses to red light therapy is a strong reduction in inflammation and oxidative stress, with significantly lower joint pain. [7,8] Red Light in this form of therapy helps reduce inflammation and improve cells, and as a bonus, blood flow is improved which promotes additional healing.


Treat winter blues or depression with Red Light Therapy

In recent years, a number of studies have been done or it could be shown that NIR (Near infrared light / Shortwave infrared light) in particular between 800nm ​​and 950nm by means of laser or LED can improve the brain structure in a way that improves depression. . Research has also been conducted on multiple forms of depression such as Seasonal Affective Disorder (wind depression / winter blues), comorbid depression, anxious depression, and others such as more common mild to severe depression. Many studies conclude that these forms of light therapy improve depression and that more specific research is needed in the coming years. In the database above, a large number of these studies can be found under the heading 'Depression'.

skin, collagen and anti-aging

Red light therapy feels so rejuvenating because it is the production of collagen, which gives the skin its elasticity, gives your hair its strength, and gives connective tissue its ability to hold everything together. [4] Numerous studies and investigations have shown that light therapy improves skin color and texture, reduces signs of aging and accelerates the healing of wounds and scars. [1,5]

Female Intimate Zone Problems

Light therapy can also help with many types of vaginal and uterine complaints. Especially for this we have the LiYonic developed. For more information where Red light therapy and in particular the LiYoni can help you can read the following articles: Intimate zone light therapy en Light therapy for fungi.

Training and muscle recovery

Numerous studies and research have shown that light therapy helps your body produce more cellular energy and reduce oxidative stress, helping tired and damaged muscle to recover more quickly. [9]

Recent 2016 research published in the American Journal of Physical Medicine and Rehabilitation, shows that the application of light therapy also promotes the growth of healthy muscle tissue, naturally increasing muscle size and volume, as well as strength. [4]

Ben GreenfieldVoted America's best personal trainer, he also swears by red light therapy for his health and performance, in addition to sex drive and other male-specific things. He wrote an important guide and answered frequently asked questions about red light therapy at the end of 2018 with a lot of good information, as well as his personal experience with his red light lamp.

Melatonin and sleep

Most people are exposed to a lot of unhealthy artificial light that disrupts your circadian rhythm and makes it more difficult to sleep. Red and Shortwave Infrared do the exact opposite and help protect your internal clock. Clinical studies show that light therapy also increases natural melatonin production for healthier sleep. [10]

Bulletproof Founder Dave Asprey swears by red light therapy for healthy sleep and even spends a chapter from his book on sleep, Game changers, to the use of red light therapy for a better circadian rhythm instead of unhealthy blue light. An article from NorahLux about blue 'junk' light can be found here.


Safe, non-invasive and drug-free

Unlike most conventional treatments, red light therapy is safe, non-invasive, uses no chemicals or drugs, and is not associated with harmful side effects. Red light therapy simply takes advantage of the natural healing and rejuvenating benefits of a specific range of therapeutic natural light and delivers this targeted energy at a higher level than the sun, without harmful UV rays. The lack of sunlight because we spend too much indoors is therefore made up for in a short time.


Dimensions for optimal handling:

Size is important in light therapy. The more surface you can cover, the better. Full, even and consistent coverage provides optimal treatment benefits, at least when it comes to your general and overall health. (For more information on which sizes are suitable for which purposes read here.)

You can undergo light therapy at specialized light therapists or salons. However, it is often time consuming to go to a salon and the costs will also add up. Why not choose to undergo light therapy in your own home? Time and cost savings! In addition, your family can also use it.

You can also watch your objective is to do light therapy. Do you only want to treat your face or your entire body?

Many customers will start with just the face but will later realize that a light therapy lamp can do so much more. That is why there are various sizes for sale so that you can choose the right LED lamp for your purpose. Depending on your objective, you can discover the benefits of the Norahlux LED lamps in 5-10 minutes a day.
