Your body doesn’t run on time. It runs on light 🌞 Blue light is not the enemy — it’s a signal. In nature, blue wavelengths from sunlight tell your brain: “Wake up. Produce cortisol. Focus. Move.” That’s how your circadian rhythm—your internal 24-hour clock—keeps every system in balance. The problem is that modern light isn’t natural. It’s isolated blue light from screens, LEDs, and fluorescent bulbs—high in stimulation, missing the balancing red and infrared light that sunlight always provides.
