Red Light Therapy

All light has some bioactive effect on the human body. The effects of light are related to each light ray’s unique wavelengths measured in nanometers (nm) and its absorption into the body.

For example, the sun produces a large spectrum of visible and invisible light. Although not visible to the human eye, UVA/UVB (100-400 nm) emits a large amount of energy that stimulates vitamin D production in the epidermis’ outer layers. Even though we can’t see this light, it’s powerful enough to burn our skin cells and leave long-lasting damage.

Another light wave that’s been extensively studied is blue light and its effects on our circadian rhythm. Blue light has been shown to suppress melatonin production, one of the primary hormones that regulate our sleep cycle.

The wavelengths of red light and near-infrared light falls between 620-800 nm, a unique therapeutic window that’s able to penetrate deep into the skin to improve cell function.

We’ve always known that there’s a lot more than meets the eye when it comes to the effects of light from the sun.

The sun is our main source for red light wavelengths. And it contributes to the mood boost we get when we spend the day outdoors.

Red light therapy devices do a lot more than emit ambient red lighting.

Remember, the wavelengths produced by the bulb are what’s important to receive health benefits.

Genuine RLT devices emit a concentrated red light energy frequency often combined with near-infrared (NIR) wavelengths to improve penetration into the skin.

NIR penetrates deeper into the skin better than any other light wavelength. Thus, this can access tissues beneath the skin, delivering benefits on a metabolic level rather than one specific area.

Effects At A Cellular Level

The mitochondria in the skin cells absorb photons. And if we can remember from high-school biology, the mitochondria is the power-house of the cell. It generates energy for the cell to perform its functions.

Boosting the mitochondrial function helps to improve:

• Electron transport
• ATP or adenosine triphosphate nitric oxide release
• Blood flow
• Increase oxygen supply

In short, cells involved in tissue repair and healing get supercharged with this form of photon energy, producing a variety of the benefits we laid out earlier including, wound healing, reduced pain, enhanced mood, reduced wrinkles, muscle repair, and more.
