Episode notes
Light's Dual Nature
- Light, unlike smoke, is essential for safety and work, requiring a nuanced approach to its use.
- We must redesign our world to optimize beneficial light spectrums (blue in daytime, orange at night) while mitigating harmful overexposure.
Light Disruption
- Artificial light exposure, especially at night, disrupts sleep and circadian rhythms, leading to various health problems.
- This disruption is particularly concerning for vulnerable populations like ICU patients and premature babies.
NICU Lighting
- A study in Mexico City demonstrated that premature babies exposed to 12 hours of darkness daily grew faster.
- These babies were discharged 13 days earlier, resulting in substantial cost savings and reduced emotional burden on families.
