And then even if you barely get outside, you're really gonna feel the effects and they're gonna be good and your body's gonna love it and your body's gonna thank you for that.

So first step, 10 to 30 minutes, morning, unfiltered, sunlight.

Just bring those activities outside.

What he did was he isolated a specific wavelength of light, 670 nanometers, which falls underneath the red light spectrum.

So it's red light.

He shined red light on the backs of participants, of healthy adults.

And he had two groups, right?
