A Guide to Red, Blue and Green Light Therapy for Healing

The Complete Guide to Color Light Therapy

Light is a powerful tool for healing. Specific wavelengths of light can interact with cells and stimulate beneficial biological processes in the body. Harnessing these effects is known as photobiomodulation, or more commonly, light therapy.

Light therapy has traditionally involved red light and near-infrared light. But more recently, blue and green wavelengths have also shown therapeutic potential.

Let's explore the science behind color light therapy and all the ways it can improve health, healing, and overall wellbeing.

Red Light Therapy

Red light therapy involves exposing the body to low-level red and near-infrared light between 600-950nm wavelengths. These wavelengths penetrate several millimeters into the skin where cells can absorb and use the light.

The light stimulates mitochondria in cells to produce more ATP energy. This powers healing processes and provides benefits throughout the body. Studies show red light can:

• Reduce inflammation and joint pain
• Improve wound healing
• Rejuvenate skin complexion and reduce wrinkles
• Stimulate hair growth
• Enhance testosterone and muscle recovery
• Protect brain function

Red light is perhaps the most researched and widely used light therapy. But other colors also offer therapeutic effects.

Blue Light Therapy

Blue light ranges from 415-520nm wavelength. It has mild antimicrobial effects that can help treat and prevent acne. Blue light penetrates pore-clogging sebum oil and kills acne bacteria like Propionibacterium acnes.

In wound healing, blue light reduces inflammation and has been shown to treat ulcers and stimulate collagen production. It may also relax muscles and ease arthritis pain.

However, too much blue light exposure from electronic devices at night can disrupt circadian rhythms and cause eye strain. Use blue light therapy carefully.

Green Light Therapy

Green light from 500-600nm activates cells to enhance healing. It has been studied for treating migraines, chronic pain, and skin conditions. Green light penetrates hemoglobin and myoglobin especially well to stimulate healing.

Research shows green LED light can reduce swelling and inflammation, accelerate wound closure, and even improve recovery from spinal cord injuries.

When combined with red light, green light therapy demonstrates greater anti-inflammatory and therapeutic effects compared to either alone.

Choosing a Light Therapy Device

Light therapy devices include:

• Red light therapy panels
• Handheld wands
• Blue and green acne masks
• Infrared saunas

Consider these factors when selecting a therapeutic light device:

Wavelengths

Match the wavelengths to your intended use. Red light panels designed for skin rejuvenation differ from pain-relieving infrared devices. Know your goal before choosing wavelengths.

Power Density

This measures light intensity or strength. It's measured in watts per square meter (W/m2). Higher power density penetrates deeper and triggers greater effects.

Look for at least 30mW/cm2 for red light and 10 mW/cm2 for blue/green light. Beware manufacturers listing total power instead of power density.

Treatment Area Size

Larger treatment areas allow you to expose more of the body at once. Multi-panel full body devices are more efficient for overall wellness compared to small wands.

Manufacturer Reputation

Seeking out reputable brands ensures device safety, quality, and results. Try to avoid cheap devices from unknown companies.

Your dermatologist or chiropractor may also offer clinical light therapy treatments in-office if you prefer professional application.

How to Use Light Therapy Devices

Using your light therapy device properly optimizes results. Follow these tips:

Protect Your Eyes

Always wear provided safety goggles. Never look directly at the light. Most devices automatically shut off when facing the eyes as a safety feature.

Clean Your Skin

Cleanse skin before red or blue light acne treatments to remove oil, makeup, and debris blocking pores. Avoid creams or gels that may scatter light.

Shave Treatment Areas as Needed

Hair can block light from reaching the skin. Shave treatment areas if needed, but avoid irritating skin.

Adjust Distance

Place light panels the recommended distance from your body, usually about 6 inches. Handheld wands should hover just over skin.

Use Consistently

Light therapy works cumulatively and benefits are seen over weeks of use. Aim for at least 3-5 sessions per week.

Cover Reflective Surfaces

Remove or cover metal jewelry and reflective surfaces to prevent scattering light. Light should penetrate skin directly.

Are There Any Side Effects?

When used correctly, light therapy is very low risk. Some minor side effects may include:

• Headache or eyestrain from improper eye protection
• Skin irritation from poor hygiene or increased pigmentation
• Feeling overly energized if used before bedtime

Using lower intensities can reduce side effects. Speak to your doctor about any concerns.

Should You Try Color Light Therapy?

Light therapy is an emerging treatment option for various conditions without the side effects of medications. The non-invasive technology carries little risk when safety guidelines are followed.

While results vary by individual and condition, most people can benefit from red and near-infrared light for skin rejuvenation, pain relief, and enhanced healing. Blue and green wavelengths show promising niche applications as well.

Speak to your healthcare provider to see if light therapy may be worthwhile incorporating into your wellness routine. The future looks bright for this innovative therapy!
