How Much is Too Much Red Light Therapy?

You know how plants use sunlight to make energy? Well, your cells can do something similar with a specific type of light: RED LIGHT.

Red light therapy uses low-power lasers or LEDs. When this red and near-infrared light hits your skin, it’s absorbed by the mitochondria.

Think of mitochondria as the tiny batteries in your cells. The red light gives them a boost, helping them produce more energy. This can help with recovery, skin health, and even sleep!

But here’s the key: you need the right dose. It’s like a supplement.

Too LITTLE? You might not see any benefits.

Too MUCH? You could actually reduce the effect or irritate your skin. The “sweet spot” is usually short, consistent sessions, and some people say every other day is best, though the science on this still remains scarce.

So how do you find your personal sweet spot? See what works for you. How do you feel? If you want to take a more scientific approach, track your red light sessions and confounders in Health Genius to see how it links with health outcomes such as sleep.
