Episode notes
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.
Circadian Rhythm Disruption
- It's not just light exposure itself but the disruption of circadian cycles that is dangerous to our health.
- Circadian rhythms are internal timetables that regulate various biological processes, impacting sleep, mood, hormone production, metabolism, and more.
SCN and Light Input
- The SCN, our master clock, receives light input exclusively through the eyes.
- Skin photoreceptors might regulate local clocks, but their impact on the master clock remains inconclusive.
