The Ultimate Guide to Red Light Therapy
1.2 How RLT Targets
Pain and Inflammation
One study explored how RLT using red or near-infrared light might help reduce pain and inflammation.

The
researchers used mice to test whether this light treatment could ease different types of pain and swelling.
They found that shining red LED (light emitting diode) light on mice for just 60 seconds before inducing pain
had some impressive effects:

sensations.
The study also looked at how this light therapy might work. It appears to interact with several systems in the
body that are involved in sensing and processing pain signals.

For example, it affects how the body responds
to glutamate, a chemical messenger involved in pain signaling.
Additionally, the red LED light showed promise in reducing ear swelling and decreasing the number of
inflammatory cells that typically rush to an irritated area.

Inflammation is the body‘s natural response to
injury or infection. It causes redness, pain, swelling, and warmth.
While these results are exciting, the researchers caution that more studies are needed to fully understand
how and why red LED therapy works to reduce pain and inflammation.

This research provides a foundation
for future studies that could lead to new pain management treatments using light therapy.
