What Is Green Light Therapy?

To fully grasp the concept of green light therapy, one must first familiarise themselves with the broader concept of light therapy.

As is suggested by its name, light therapy harnesses the power of various types of light. This includes ultraviolet light, known for its potential to cause sunburn and infrared light, the warmth-giving component of sunlight and the heating element in Clearlight® Saunas.

Next on the spectrum is visible light, which encompasses all colours of the rainbow, ranging from purple and blue through to green, yellow, orange, red, and everything in between.

In the realm of physics, these diverse types of light are differentiated by their wavelength, each of which has a unique effect.

For example, blue light at 480 nanometres (nm) may enhance skin health and alertness, while red light at 630nm is known to boost energy production and reduce inflammation.

Then we have green light, spanning from 500nm to approximately 570nm, which is the focus of our discussion today.

Next up, we're going to talk about green light therapy in the broader aspect of LED light therapy, and how it can enhance your wellness journey when used inside Infrared Saunas.

Green Light Therapy As Part Of LED Light Therapy

Throughout the ages, our ancestors were naturally exposed to green light via sunlight. However, in our modern world, we have the ability to harness artificial light, allowing us to expose our bodies to various light types at will.

The technique known as LED light therapy is quite versatile in its application.

Initially, you can choose green LEDs that emit light at specific wavelengths, such as 530nm or 550nm. Alternatively, you can generate light perceived as green by blending colours.

This principle of colour mixing is something many of us learned in primary school, where secondary colours are created by combining the primary colours of blue, red, and green.

The chromotherapy feature in our saunas adopts this method, emitting Red light at 660 nm, green at 540 nm, and blue at 405 nm.

By mixing these lights, you can create yellow light (red and green), violet light (red and blue), and even orange light (green and blue).

Interestingly, green light, especially when implemented through LED light therapy, has been found to have distinct health benefits.

In the following section, we'll delve into some of these health advantages:

Benefits Of Light Therapy Green Lights

Let’s consider the LED green light therapy benefits. Almost 100 studies exist on the benefits of green light therapy, and in this blog, we’ll cover the most important ones below.

What Does Green LED Light Do For Skin?

Firstly, let's explore the benefits of green LED light for skin.

Multiple studies have delved into the impact of green light on skin health (1; 2; 3; 4). It's been found that green LED light can stimulate the production of fibroblasts, which are fundamental to maintaining the structural integrity of the skin and promoting wound healing.

Secondly, the effects of green light extend directly to skin cells.

It not only facilitates the creation of new skin cells but also aids their migration to areas where they're most needed.

In some aspects related to skin health, the impact of green light therapy even surpasses that of red light therapy.

Furthermore, green light therapy enhances blood flow within the skin and promotes the formation of new blood vessels.

These additional blood vessels subsequently improve circulation, which in turn contributes to healthier skin.

The natural aging process often leads to a decline in blood vessel health and blood circulation, resulting in deteriorating skin health and appearance.

Therefore, the benefits of green light for skin health present a significant advantage.

Does Green LED Lights Help Headaches? And What About Other Pain Types?

Recent studies have revealed the remarkable potential of green LED lights in reducing headache intensity (5; 6; 7; 8). Astonishingly, even those suffering from chronic headaches and migraines can experience a decrease in the number of days affected by such discomfort through the use of green LED lights.

The outcome of these studies points towards a significant enhancement in quality of life, with no reported side effects.

Furthermore, green light has been found to elevate the levels of GABA, or Gamma-AminoButyric Acid, in the brain.

To put it simply, GABA is the brain's chief relaxant neurotransmitter, responsible for sending signals within the brain. Essentially, green light helps to calm the nervous system, thereby leading to a reduction in pain.

Additionally, some studies suggest that green light aids in releasing natural opioids, the body’s endogenously produced painkillers.

Not to mention, green light also exhibits anti-inflammatory properties. Consequently, the benefits of green light extend beyond headaches to other types of pain, including nerve pain.

While further research is required in this area, the preliminary results published to date are incredibly promising.

Just imagine the potential benefits you could reap from incorporating green light therapy into your wellness routine with a Clearlight® 2-Person Infrared Sauna!

Is Green Light Good For Sleep?

You may wonder, "Does green light therapy aid sleep?"

The answer isn't straightforward—it depends. When green light penetrates your eyes during the day, it signals to your body's internal day-night rhythm, or "circadian rhythm", that it's time to awaken (9; 10; 11).

This rhythm is primarily influenced by green and more so by blue light.

For hundreds of thousands, even millions of years, sunlight was the primary indicator for our ancestors' biological clocks to differentiate between day and night.

During the day, exposure to sunlight's blue and green light kept our ancestors alert and awake.

Conversely, at night, the lack of sunlight (and hence blue and green light) increased melatonin production in the brain, promoting better sleep quality.

So, what does this mean for you as a Clearlight® Infrared Sauna user?

Quite simply, when utilising chromotherapy features within your sauna, it's advisable to use the green light during daylight hours and possibly early evening.

Using the 540nm light provided by our chromotherapy late into the night could inhibit the production of melatonin in your brain, potentially affecting sleep quality.

Only the red light is considered safe for use late at night in this regard.

Other Green Light Effects

Indeed, the benefits of green LED lights aren't limited to those already mentioned.

Current evidence suggests that green LED light therapy can influence both fat loss and muscle mass gains. With over 100 studies published on green light therapy, the majority of which are positive, it's likely that further benefits of green light will be unveiled as more research is conducted in this field.

In conclusion, Clearlight® Infrared Saunas' chromotherapy, particularly green light therapy, offers an array of potential benefits. From skin health and pain reduction to improved sleep and potentially even fat loss and muscle gains, the possibilities are impressive.

Green Light LED Therapy Frequently Asked Questions

Let's delve into some frequently asked questions about Green Light LED Therapy that may not have been addressed in the previous blog post:

What Is The Difference Between Green And Yellow Light Therapy?

Green LED light typically falls within the 500 - 570nm range, while Yellow is often found around the 570-600nm range.

Beyond 600nm, you'll encounter red light.

There isn't a strict definition of where yellow begins and green ends; it's common to refer to the entire spectrum up to 600nm as "green light".

However, it's worth noting that light in the lower and higher 500s may have subtly different health effects.

Is Green LED Light Good For Sleep?

Indirectly, yes. Green LED light can be beneficial for sleep if used during daylight hours.

When green light below 550nm enters your eyes during the day, it signals your body to wake up and boost alertness, similar to the effects of coffee.

It's recommended to avoid using green light, even from chromotherapy, late at night before bedtime.

What Effect Does Green Light Have On Humans?

As previously discussed, green light has proven benefits for skin health, wound healing, pain relief (including nerve pain and migraines), muscle development, fat loss, and circadian rhythm regulation.

While other benefits exist, the evidence supporting these is currently limited.

Are Green LEDs Brighter Than Red LEDs?

Green LEDs aren't necessarily brighter than red ones. However, they may appear brighter at the same intensity due to our eyes being more attuned to detecting green hues.

This perceptual bias likely evolved because of the abundance of green in our natural environment, where accurate perception was essential for survival.

Is Green Light Or Red Light Therapy Better?

Both therapies offer significant benefits, so ideally, you'd want to utilise both. While there are considerably more studies on red light therapy (7,000+) than green light therapy (100+), this could suggest that many potential benefits of green light have yet to be scientifically discovered.

Is Red Light Better Than Green Light For Face?

From an evidence-based perspective, red light holds more substantial backing for facial treatment than green light.

Why Is Green Light Better At Night?

Green LED light isn't necessarily better at night, but it's less detrimental than blue light. For optimal sleep, consider using red LEDs in your home, as red light doesn't suppress melatonin levels in the brain.

Is Green Light Good For The Brain?

Currently, green light's benefits for the brain are primarily related to pain and headache relief.

However, there's a lack of extensive research exploring green light's effects on cognitive function, particularly in humans.

What Colour LED Lights Help With Headaches?

Green LED light has shown promising results in alleviating headaches and even migraines. Studies indicate a significant reduction in both the number of headache days and their intensity.

Many migraine sufferers keep a green LED light near their work desks to prevent migraines from developing. Similarly, you can use chromotherapy in your Clearlight® Infrared Sauna for headache relief.
