Near-Infrared (NIR) Light Therapy

Light therapy (phototherapy) refers to the use of light at specific frequencies and intensities in order to affect our physiology. In most cases, the effects of light therapy are not mediated through eyesight, but rather by the lights directly affecting the target cells.

Infrared light therapy is a form of light therapy, which involves getting exposed to sufficient intensity of infrared light to experience health benefits. The infrared spectrum is the invisible light with frequencies below that of the red light. It is why we feel gentle radiant heat when we are exposed to the sun because infrared creates heat in our tissues. However, the infrared spectrum also affects our physiology in other ways.

Here's a video from an independent party who provides useful details on NIR Light Therapy.

In my experience, NIR light therapy indeed does help with muscle and joints pain.  I have also experienced other benefits.

I purchased, used and recommend the Joovv Go - NIR (as opposed to Red).  Aside from convenience, I personally don't see the additional benefits or the need to buy a more expensive unit.
