Red Light Therapy: What It Actually Does (No Hype)

Red light therapy has been showing up everywhere — Instagram, TikTok, Amazon bestseller lists. But what does it actually do, and is it worth your money?

Here's the no-hype version.

Red light therapy uses specific wavelengths of light (typically 660nm red and 850nm infrared) that penetrate your skin and reach your muscle tissue. The light stimulates your cells to produce more energy, which speeds up recovery and reduces inflammation.

What it's been shown to help with:
- Muscle soreness after exercise
- Joint stiffness
- Surface-level inflammation
- General recovery time

What it's NOT:
- A miracle cure for chronic pain
- A weight loss tool
- A replacement for medical treatment

The research is real but still developing. Most studies show modest but consistent benefits for recovery and inflammation. It's not going to fix a torn rotator cuff, but it may help you recover faster between workouts.

A red light therapy belt that combines heat and vibration with red light gives you three recovery tools in one. At $50-70, it's a fraction of what clinical red light panels cost.

Our take: worth trying if you're serious about recovery, not worth expecting miracles from.
