Key Takeaways
Few people are currently aware of the power of the colors that surround us, however, they have a significant impact on our lives. Through scientific research, it has been proven that color (as a wave) is not only perceived by the eye, but also by all cells of the human body. Presented as a beam of colored light, it can influence our emotional state and physiological reactions.

Chromotherapy is a concept
The basic premise of chromotherapy is that the colours of the electromagnetic spectrum are capable of supporting the treatment of diseases. The generated light pulses carry with them energy that stimulates or suppresses biochemical and hormonal processes, depending on the desired therapeutic effect.
Chromotherapy physiological mechanisms of action
When monochromatic light reaches our eyes, it stimulates the photoreceptors of the retina, which in turn transmits a nerve impulse to the brain, and some parts of that organ are sensitive and respond to the colors of the visible light spectrum, and the proper functioning of the human body is largely dependent on the action of the subcutaneous tissue, the brain vessels and the spinal cord.
Chromotherapy therapeutic use
Nowadays, color therapy is a treatment method that is developing very rapidly and is increasingly being used in various fields. It is widely used in cosmetology and increasingly in medicine. Chromotherapy supports the treatment of pain of various origins, depression, and even diabetes.
The effects of colored light
The physiological impact of colored light correlates with precise electromagnetic wavelengths: Red light (longer wavelengths) stimulates peripheral microcirculation, enhances mitochondrial ATP synthesis, and elevates vitality. Blue light (shorter wavelengths) exerts notable soothing, antimicrobial, and anti-inflammatory effects, lowering heart rate and promoting calm. Green light serves as an autonomic equalizer, soothing tension and fostering recovery, while yellow light stimulates digestive enzyme production and cognitive focus.
