Green Light Therapy

Green light therapy is a cutting-edge, non-invasive treatment that uses specific wavelengths of green light to promote healing, reduce pain, improve mood, and restore natural sleep rhythms.

Unlike harsher forms of light exposure, green light is gentle on the eyes and body, yet clinically shown to deliver powerful therapeutic effects—making it an ideal option for individuals suffering from chronic migraines, fibromyalgia, circadian rhythm imbalances, or mood disorders.

With no known side effects and growing support from peer-reviewed research, green light therapy offers a safe, natural alternative to medication-based interventions.

 
 
 

Discover the Healing Power of Green Light Therapy

Green light therapy is an emerging, drug-free solution offering profound benefits for people struggling with pain, migraines, poor sleep, and mood disorders. Backed by a growing body of clinical and neuroscientific research, this gentle yet powerful therapy harnesses specific wavelengths of green light (typically around 525nm) to rebalance your body’s natural rhythms and ease discomfort—without side effects.

What Is Green Light Therapy?

Green light therapy involves exposure to a controlled spectrum of green light emitted from LED sources. Unlike conventional white or blue light, green light has been shown to stimulate the brain and body in unique, beneficial ways. It works through both visual and non-visual pathways—interacting with the brain’s internal clock (circadian system), pain processing centres, and mood-regulating structures.

Proven Benefits of Green Light Therapy

1. Pain Reduction Without Drugs

  • In a University of Arizona clinical trial, fibromyalgia patients reported significant pain relief after just 10 weeks of daily green light exposure—with no side effects.

  • Green light was shown to increase natural opioids in the body and reduce neuroinflammation, making it highly promising for chronic and post-surgical pain.

2. Migraine Relief

  • Chronic migraine sufferers experienced up to 12.9 fewer headache days per month following green light therapy. Pain intensity scores dropped from 8.0 to 3.2 on a 10-point scale.

3. Enhanced Mood and Circadian Rhythm Balance

  • Green light influences the brain's mood-regulating centres such as the hypothalamus and prefrontal cortex through non-visual retinal pathways.

  • It helps realign the circadian clock—improving sleep quality, alertness, and overall emotional well-being.

4. No Known Adverse Effects

  • Across multiple studies, green light therapy demonstrated a strong safety profile with no measurable side effects—even with daily use.

Is It Right for You?

Green light therapy is suitable for:

  • Individuals with chronic pain (e.g. fibromyalgia, migraines, arthritis)

  • People experiencing poor sleep or irregular circadian rhythms

  • Those seeking a natural, non-pharmacological mood support tool

  • Patients with post-operative pain looking to reduce reliance on opioids
