How It Works
Another way to explain the benefits of red light is through the lens of Eastern medicine. Ask a Traditional Chinese Medicine practitioner how light helps improve health, immunity, and recovery, and he or she will likely compare it to acupuncture’s mechanism of action:
Light is a form of energy, and our bodies are just big energy systems. Light has the power to stimulate specific meridian points and chakra zones in the human body.
Red is said to stimulate the first chakra because it correlates most strongly with our survival instinct (hence why it gives us energy and makes us act quickly, in order to motivate us to pursue things like money, food, sex, power, etc.).
While acupuncture uses tiny needles to achieve bodily harmony by stimulating certain points in the body’s energy system, light therapy uses focused, visible, red wavelengths in much the same way.
Red light has been shown to be naturally energizing and correlated with improved moods by increasing self-confidence, positivity, passion, joyfulness, laughter, social awareness, conversation skills, and sensory stimulation. While results vary from patient to patient, there’s reason to believe that LLLT has mental and emotional perks in addition to physical benefits.
