What is the best wavelength for red light therapy?
However, the bulk of clinical literature suggests that light in the mid-600 nm range and low- to mid-800 nm range is the most effective. That is because these wavelengths have the greatest effect on the cellular respiration process.
How many nanometers is red light?
WAVELENGTHS OF VISIBLE LIGHT As the full spectrum of visible light travels through a prism, the wavelengths separate into the colors of the rainbow because each color is a different wavelength. Violet has the shortest wavelength, at around 380 nanometers, and red has the longest wavelength, at around 700 nanometers.
What nanometer is red?
The visible spectrum
| colour* | wavelength (nm) | energy (eV) |
|---|---|---|
| red | 650 | 1.91 |
| orange | 600 | 2.06 |
| yellow | 580 | 2.14 |
| green | 550 | 2.25 |
What does red light do to the brain?
The theory is that red light wavelengths stimulate the production of melatonin. Melatonin is a naturally occurring hormone that helps you sleep. Your brain releases more melatonin as darkness falls and tends to release less when you’re exposed to light.
Is red light bad for your eyes?
Conclusion: Red Light Helps Protect and Heal Your Eyes. Red light therapy treatments, with both red and near infrared wavelengths, aren’t just safe for eyes. They’re also a proven way to help heal eye injuries, reduce inflammation, and protect against vision loss, as shown in numerous peer-reviewed clinical studies.
What does red light do for humans?
Red light therapy (RLT) is a treatment that may help skin, muscle tissue, and other parts of your body heal. It exposes you to low levels of red or near-infrared light. Infrared light is a type of energy your eyes can’t see, but your body can feel as heat. Red light is similar to infrared, but you can see it.
What is red light made of?
Red Light. All light is made up of different wavelengths on the electromagnetic spectrum. Visible light ranges from red, which has longer wavelengths, to violet, which has shorter wavelengths. Each wavelength corresponds with a different color of the rainbow.
Can red light hurt your eyes?
Red light therapy is a safe, natural way to protect your vision and heal your eyes from damage and strain, as shown in numerous peer-reviewed clinical studies.
Are red LED lights bad?
Short answer is because human eyes don’t respond well to the color red, so it’s a very poor color choice for illumination purposes. Longer answer is the whole idea of having lights at night is to be able to see things at night.
