The Unique Benefits of Red and Near-Infrared Light
Among the five types of bioactive light, red and near-infrared (NIR) light stand out for their profound effects on cellular function and overall health. These wavelengths offer a promising approach to addressing some of the health issues associated with our modern light-deficient lifestyles.
Let's have an overview of red light therapy benefits.[1]
How red and NIR light penetrate human tissue
One of the key advantages of red and NIR light is their ability to penetrate human tissue:
- 🔴 Red light (620-750 nm): Can penetrate about 8-10 mm into the skin
- 🟣 Near-infrared light (750-1200 nm): Can reach depths of up to 5 cm
This deep penetration allows these wavelengths to affect not just the skin, but also:
- Muscle tissue
- Bone
- Blood vessels
- Even the brain (through the skull)
Interesting fact: While most light is absorbed or reflected by the skin, red and NIR light can reach into the body, making them uniquely suited for "photobiomodulation" - the use of light to stimulate, heal, and regenerate body tissues.

Historical exposure to red and NIR light
Our ancestors were exposed to significant amounts of red and NIR light through two primary sources:
- Sunlight: The sun emits a full spectrum of light, including ample red and NIR wavelengths.
- Fire: Evening gatherings around fires provided additional exposure to these beneficial wavelengths.
"We used to be exposed to far more light and of the right wavelengths because our ancestors spent hours each day working under the sun and spent evenings around the fire, both of which emit ample red and near-infrared light."
This historical context helps explain why our bodies respond so positively to red and NIR light - we evolved with regular exposure to these wavelengths.
In our modern indoor environments, however, we're often deficient in these beneficial light wavelengths:
- Most artificial lighting lacks significant red and NIR components
- Windows filter out much of the NIR light from sunlight
- Urban lifestyles often mean less time outdoors during daylight hours
This deficiency may contribute to various health issues and explains why targeted red and NIR light therapy can have such profound effects.
Key takeaway: Red and near-infrared light offer unique benefits due to their ability to penetrate deeply into our tissues and positively influence cellular function. Understanding these benefits helps explain why red light therapy has emerged as a promising tool for addressing various health concerns in our light-deficient modern world.
