About light spectrum

The light spectrum is made up of different colors, each with its wavelength and energy. The colors can be divided into two main categories: visible and invisible.

Visible light makes up the familiar rainbow of colors we see daily. It includes red, orange, yellow, green, blue, indigo, and violet.

Invisible light includes:

  • Ultraviolet (UV) light has a shorter wavelength than visible light but more energy. UV light is invisible to the human eye but can cause sunburns or skin cancer if overexposed.
  • Infrared (IR) light has a longer wavelength than visible light but less energy. IR light is used in night-vision goggles and thermal imaging cameras.

Red light is a type of visible light with a longer wavelength than other colors. It is often used in stoplights, brake lights, and taillights because it is the easiest color for human eyes to see.

Red LED lights are made up of tiny semiconductor chips that emit light when an electric current is applied. The wavelength of the red LED light falls within the range of infrared (IR) radiation, which makes it invisible to the human eye.

What is red light therapy and how does it work?

Red light therapy is a type of phototherapy that uses red-colored light-emitting diodes to radiate monochromatic light at 630–870 nanometers (nm).

The exact mechanism by which this happens is not fully understood. But the theory behind how red light therapy works is:

  • When the photons from the LEDs interact with mitochondria in the cells, resulting in increased production of ATP (cellular energy).
  • It, in turn, leads to stimulating cellular activity.
  • Red light therapy also helps to increase circulation and reduce inflammation.

Red light therapy has many benefits, but more research is still needed to confirm all of its claims.

Primary benefits of red light therapy

As you understand, red light has a complex approach to the body. That’s why we can expect significant benefits from this form of therapy. Below you can see some of them.

Wound healing

It is a complex process that involves different mechanisms working together:

  • The nervous system coordinates the body’s response to an injury, which releases chemicals that trigger inflammation. It increases blood flow to the area, bringing nutrients and oxygen essential for healing.
  • At the same time, the body begins to repair damaged tissue by producing new cells. This process is known as regeneration, and it’s how the body replaces lost tissue or organs over time.

Red LED light therapy can help support natural healing by participating in all these processes.

Muscles recovery

One of the most common ways people use red LED light therapy is for muscle recovery. Red LED light therapy can help reduce inflammation and promote healing after intense workouts. You’ll have significantly less muscle soreness and pain after using the red light device.

Red LED light as a pain-killer

Red LED light can be used as a pain-killer. Apparently, it works by stimulating the production of hormones that block pain signals from the brain, lowing inflammation, and supporting the healing process.
