We’ve all heard of ultra-processed foods.
What about ultra-processed light?
Ultra-processed food drives obesity and chronic disease but ultra-processed light does the same.
→ Unprocessed light (sunlight) sets your circadian rhythm, supports mitochondrial health, improves mood, regulates hormones, and so much more.
→ Processed light (fire, candle, incandescent) is more aligned with human biology. Just like some processed foods it can be good for you.
→ Ultra-processed light (LEDs, screens, blue-rich bulbs at night) disrupts melatonin, sleep, metabolism, and hunger cues.
If you’ve cleaned up your food.
Now it’s time to clean up your light.
→ Get outside within 30 minutes of waking.
→ Work near an open window & take light breaks.
→ Avoid bright overhead LEDs after sunset.
→ Use circadian friendly low level lighting.
→ Wear blue blockers at night.
Natural light is a nutrient.
Ultra-processed light is a junk input.
If you want optimal health, eat real food and live under real light.
