If you’ve heard about infrared light therapy (ILT) but aren’t sure what it is or how it works, you’re in the right place. This beginner’s guide will break down everything you need to know—from the science behind it to how you can use it at home.
By the end, you’ll understand:
✔ What infrared light therapy is (and how it differs from regular light).
✔ How it works in the body (the science made simple).
✔ Key benefits (pain relief, skin health, recovery, and more).
✔ How to try it safely (devices, timing, and precautions).
Let’s dive in!
What Is Infrared Light Therapy?
Infrared Light: The Invisible Healer
• Infrared (IR) light is part of the electromagnetic spectrum, just like visible light—but our eyes can’t see it.
• It’s naturally emitted by the sun (and even your own body as heat!).
• Unlike ultraviolet (UV) light, which can damage skin, infrared is safe and therapeutic.
Types of Infrared Light Used in Therapy
There are three types, classified by wavelength (measured in nanometers, nm):
|
Type |
Wavelength |
Penetration Depth |
Common Uses |
|
Near-Infrared (NIR) |
700–1400 nm |
Deep (muscles, joints) |
Muscle recovery, wound healing |
|
Mid-Infrared (MIR) |
1400–3000 nm |
Moderate (soft tissue) |
Circulation, pain relief |
|
Far-Infrared (FIR) |
3000 nm–1 mm |
Surface (skin) |
Detox, relaxation (saunas) |
Most at-home devices use NIR (810–850 nm) and red light (630–660 nm) for maximum benefits.
How Does Infrared Light Therapy Work?
The Science Made Simple
When infrared light reaches your skin, it’s absorbed by your cells and triggers photobiomodulation—a fancy term meaning “light stimulates healing.” Here’s what happens:
1. Boosts Cellular Energy (ATP Production)
◦ Light energizes mitochondria (your cells’ power plants), helping them produce more ATP (energy).
◦ This speeds up tissue repair and reduces inflammation.
2. Increases Blood Flow
◦ Infrared light dilates blood vessels, improving circulation.
◦ More oxygen + nutrients reach damaged areas for faster healing.
3. Reduces Pain & Inflammation
◦ Blocks pain signals and lowers inflammatory markers (like IL-6).
◦ Studies show it helps with arthritis, back pain, and sore muscles.
4. Stimulates Collagen & Skin Repair
◦ Red light (630–660 nm) boosts collagen, helping with wrinkles, acne, and scars.
Top Benefits of Infrared Light Therapy
✅ Pain Relief – Helps with joint pain, muscle soreness, and chronic conditions.
✅ Faster Recovery – Athletes use it to heal muscles and tendons quicker.
✅ Skin Rejuvenation – Reduces wrinkles, acne, and sun damage.
✅ Improved Sleep & Relaxation – FIR saunas promote deep relaxation.
✅ Enhanced Circulation – Great for people with poor blood flow.
📌 Fun Fact: NASA originally studied red light therapy for wound healing in space!
How to Use Infrared Light Therapy at Home
Types of Devices
1. Panels (Joovv, MitoRed) – Best for full-body treatment.
2. Handhelds (FlexBeam, Tendlite) – Great for targeted pain relief.
3. Saunas (HigherDOSE, Clearlight) – Detox and relaxation.
4. Masks (CurrentBody, Omnilux) – Anti-aging and acne treatment.
Beginner Protocol
• Distance: 6–12 inches from skin.
• Time: Start with 5–10 minutes per area, 3–5x/week.
• Consistency: Best results come after 4–8 weeks of regular use.
⚠ Safety Tips:
• Avoid looking directly at the light (use goggles if needed).
• Don’t overdo it—more isn’t always better!
• Check with a doctor if you’re pregnant or have photosensitivity.
Myths vs. Facts
❌ Myth: “Infrared light is the same as tanning beds.”
✅ Fact: Tanning beds use harmful UV rays, while ILT uses safe infrared/red light.
❌ Myth: “You need to feel heat for it to work.”
✅ Fact: NIR works without heat—it’s about light penetration, not warmth!
Final Thoughts
Infrared light therapy is a safe, natural, and science-backed way to support healing, reduce pain, and improve overall wellness. Whether you choose a panel, handheld device, or sauna, the key is consistency.
