The shock revelation that light bulbs are wrecking your metabolism

Since the 2000s, our light exposure has changed drastically as we make our buildings more energy-efficient. Now, we’re discovering how this may mess with our mitochondria, contributing to diabetes, dementia and more

The top 3

  1. Blue Light's Dominant Role in Metabolic Dysfunction: Excessive exposure to artificial blue light, especially at night, suppresses melatonin production, disrupts circadian rhythms, and is linked to impaired glucose metabolism, insulin resistance, and increased risk of weight gain and metabolic disorders.
  2. The Protective Power of Red and Near-Infrared Light: Red and near-infrared light therapy, or photobiomodulation, may support metabolic health by improving mitochondrial efficiency, increasing ATP production, enhancing cellular energy, and reducing oxidative stress and inflammation.
  3. Warm vs. Cool White LEDs: Subtle Metabolic Differences: While all artificial light at night can be disruptive, cool white LEDs with higher blue light content may have a more pronounced negative impact on melatonin suppression and circadian rhythms compared to warmer white LEDs, which have less blue light.
