The benefits of red light therapy for health and skin come from using the red light wavelength in the 600 nanometer range. In this article, we will explain the color and wavelength of red light, the spectrum, and which wavelength of red light is most suitable for phototherapy treatment.
What is the wavelength of red light
The wavelength of red light is in the range of 620 to 750 nanometers on the electromagnetic spectrum, which is the full spectrum of visible and invisible light from the sun reaching the Earth.
Red Light Wavelength, Color, and Visible Spectrum
Light is energy from the sun that exists in different wavelengths and colors. The sun emits full-spectrum light, including all colors and waves on the electromagnetic spectrum.
The visible spectrum includes the following colors and wavelengths:
Violet light (380-450 nm)
Blue light (450-495 nm)
Green light (495-570 nm)
Yellow light (570-590 nm)
Orange light (590-620 nm)
Red light (620-750 nm)
What is the optimal wavelength for red light therapy
What are the wavelengths of red light and red light therapy? Effective red light therapy devices like Sgrow use wavelengths in the mid-range of 600 nanometers. These wavelengths have been tested and studied in peer-reviewed clinical research and have been found to be safe and beneficial for various aspects of human health, including skin, pain, and overall physical performance.
What is the difference between red light and near-infrared light (NIR)
Red light is easily absorbed by surface tissues and cells, potentially enhancing skin health and healing capabilities.
Near-infrared light, which is invisible to the human eye, can penetrate deeper into tissues and may enhance recovery and support inflammation.
Red Wavelengths in Sgrow Light Therapy Treatments
Due to advances in LED technology, Sgrow is able to isolate specific wavelengths of red and near infrared light that are most effective for overall health and wellness. These are red wavelengths in the mid-600 nm range and near infrared wavelengths in the mid-800 nm range, which are the most extensively studied and tested wavelengths. When you turn on the Sgrow device, you can choose between visible red light and/or near infrared light that is invisible to the human eye.
Red Light Wavelengths and Blue Light Wavelengths
Blue light wavelengths are in the 450 to 495 nanometer range and have a higher frequency (or shorter wavelength) than red light. Blue light is also much brighter than red light, which is why when you absorb too much blue light from screens and artificial lighting at night, it can cause sleep problems and headaches.
Red light therapy is a great way to combat blue light, especially with features like Sgrow’s Ambient Mode. Ambient Mode provides a lower intensity light that’s perfect for nighttime use.
Conclusion: Red Light Wavelengths Have Been Proven to Work
Red light therapy works because red light wavelengths have a positive impact on human cellular health, potentially benefiting the skin, muscles, and joints. Red light wavelengths range from 620 to 750 nanometers, but for effective light therapy treatments, isolated red light wavelengths in the mid-600 nanometer range are best. The Sgrow device delivers these specific frequencies of red light, which have been clinically proven to improve health and wellness.
