Is Infrared the Same as Red Light Therapy?: Understanding the Differences in Light Therapy

No, infrared therapy and red light therapy are not the same, though they’re related and often used together in wellness and beauty treatments. Both are forms of phototherapy, meaning they use specific wavelengths of light to produce therapeutic benefits for the body. Here’s a closer look at their differences and similarities:

Red light therapy uses visible red light, typically in the range of 620-700 nanometers. It’s absorbed mainly by the skin’s superficial layers and is most commonly used for skin rejuvenation, boosting collagen production, reducing inflammation, and aiding in healing surface wounds.

Infrared therapy refers to the use of wavelengths longer than visible light—specifically, near-infrared (700-1400 nm) and far-infrared (3,000 nm and beyond). Infrared light penetrates deeper into tissues, reaching muscles, joints, and even bones. It’s commonly used for pain relief, muscle recovery, improved blood circulation, and reducing deeper inflammation.

So, while both red and infrared therapies use light to deliver benefits, the primary difference lies in their wavelengths and how deeply they penetrate. Many modern devices actually combine red and near-infrared light for a more comprehensive treatment.

As a designer, I often consider how lighting—including therapeutic types like red and infrared—affects the comfort, functionality, and atmosphere of a space. For example, when planning AI Interior Design projects that integrate wellness features, understanding the placement and specification of light therapy devices ensures users enjoy both beauty and health benefits seamlessly in their environment.

Tips 1:

If you’re designing a home wellness space or spa, consider both the functional needs (like easy electrical access and ventilation) and the aesthetics (calming colors, soft materials). Position therapy devices where users can comfortably and safely access them, and look for multi-modal units that combine red and infrared light for versatility.

FAQ

Q: Is red light therapy the same as infrared therapy?

A: No, red light uses visible red wavelengths, while infrared uses wavelengths outside the visible spectrum, penetrating deeper into tissues.

Q: Can I use both red and infrared lights together?

A: Yes, many devices combine both for complementary benefits—red targets skin, while infrared reaches deeper muscles and joints.

Q: Which is better for skin issues?

A: Red light therapy is typically better for surface skin concerns like aging and inflammation.

Q: Does infrared therapy help with pain relief?

A: Yes, infrared light penetrates deeply to help with muscle and joint pain.

Q: How should light therapy devices be incorporated into interior design?

A: Ensure they are easily accessible, have safe installation (considering power and ventilation), and that their style fits with the overall room design for a cohesive, relaxing space.
