How light hits your brain — and what happens next

Your body doesn't just see light — it reads it like a clock. Sunrise red sets your cortisol. Mid-morning UV drives serotonin. Midday blue signals peak alertness. Your indoor environment is broadcasting those same signals at night, and your biology can't tell the difference. Click any wavelength below to see what it triggers inside your body.

What this means for your biology

Your home's light environment has never been measured.

Most people don't know what artificial light patterns their home is generating at night. We bring calibrated instruments to assess spectrum, flicker, and blue light exposure in the areas where you sleep and recover.
