Difference Between Infrared and Red Light Therapy: 1 Minute to Understand Their Unique Benefits

Infrared and red light therapy are both popular modalities in the field of photobiomodulation, a therapeutic process that uses specific wavelengths of light to promote healing, reduce inflammation, and alleviate pain. Though these two therapies often get mentioned together, they differ in terms of their wavelength, penetration depth, and applications.

Red light therapy typically operates at wavelengths between 620 nm and 750 nm, making it visible to the human eye. This therapy is primarily used for surface-level treatments, such as skin rejuvenation, wound healing, and reducing fine lines, due to its relatively shallow penetration into tissues.

Infrared light therapy, more specifically “near-infrared” (NIR), uses wavelengths ranging from 750 nm up to around 1100 nm. This light is invisible to the naked eye and penetrates deeper into the body—reaching muscles, joints, and even bones. This deeper reach is why infrared is commonly used for pain management, improving circulation, and addressing deeper tissue issues.

Both therapies work by stimulating cellular activity and promoting the production of ATP (adenosine triphosphate), the energy currency of our cells. Choosing between the two depends largely on your therapeutic goals: for surface skin concerns, red light is preferred; for deeper muscular or joint issues, infrared is typically more effective.

As a designer, I’m always fascinated by how light—whether for therapy or for ambiance—can shape our experience of interior spaces. If you’re considering integrating wellness tech into your home, thinking about their placement goes beyond aesthetics. Location near areas where you typically relax, combined with good ventilation and thoughtful spatial planning, enhances function and accessibility. In fact, when planning multi-purpose spaces or wellness corners, I often utilize a room planner to visualize natural and supplemental lighting—ensuring both therapeutic devices and design elements coexist harmoniously.

Tips 1:

When adding light therapy devices to your home, consider their recommended distance to your body and the size of their coverage area. Incorporate them into your daily routine by placing them near a reading nook or meditation corner, ensuring the devices complement your decor and don’t disrupt the flow of traffic in the room.

FAQ

Q: What is the key difference between infrared and red light therapy?

A: The main difference is penetration depth. Red light targets surface tissues while infrared reaches deeper into muscles and joints.

Q: Is infrared or red light therapy better for skin care?

A: Red light therapy is generally preferred for skin care due to its effectiveness in treating surface-level concerns.

Q: Can I use both types of light therapy together?

A: Yes, many devices combine both red and infrared light for comprehensive treatment, as they complement each other.

Q: Are these therapies safe for home use?

A: Generally, both are safe when used as directed, but it’s best to follow manufacturer instructions and consult a healthcare professional if you have concerns.

Q: Can the effects of light therapy be enhanced by room design?

A: Absolutely. Strategic placement, ambient light control, and the use of a room planner can optimize both the functional and aesthetic impact of wellness devices in your home.
