What are the penetration depths of infrared light therapy?

The correct penetration depth for infrared light therapy typically ranges from 0.8 mm to 2 mm into the skin tissue. This range is significant because infrared light operates at a wavelength that allows it to be absorbed by the deeper layers of the skin. The therapeutic effects, such as increased circulation, reduced inflammation, and pain relief, are attributed to the ability of infrared light to penetrate beyond the superficial layers and reach deeper tissues.

When assessing the effectiveness of infrared therapy, understanding the penetration depth is crucial as it determines how deeply the light can interact with biological tissues to elicit a response. This information guides practitioners in optimizing treatment protocols for conditions requiring deep tissue penetration, thereby providing better therapeutic outcomes.
