Red light Effect

The benefits of near-infrared light wavelengths: Near-infrared light (NIR)wavelengths are longer than red light wavelengths, and measure between 700 nm and1,100 nm. They penetrate deeper into the tissue to deliver energy to the body’s cells and can pass through bone to assist with healing deep wounds, muscle aches, nerve injury or joint pain.

One recent study even demonstrated that when near-infrared light is delivered at the appropriate fluence or dose, the wavelengths can penetrate to a depth of 3cm to alleviate symptoms associated with traumatic brain injury, offering neuroregenerative benefits. Further clinical research found that NIR can help reduce headaches, anxiety, sleep disturbance and cognitive impairment.

In the diagram below, you can see that deep red and near-infrared light wavelengths between 650 and 950 nm penetrate deeper than any other wavelength on the spectrum.
