Episode Details

Most circadian advice stops at blackout curtains and putting your phone down. But the biology was never the hard part — the hard part is that no single body treats light and time as public infrastructure. Drawing on a listener's thought experiment, this episode works through the real evidence: a 2025 NHANES analysis linking the lowest quartile of circadian synchronization to 70% higher all-cause mortality, the 2026 Physiological Reviews cardiovascular case, and the melanopic EDI standard that explains why a light can look dim and still be biologically loud. Then the two levers — working hours and outdoor lighting — and why their evidence bases are nowhere near equal. California SB 328, CIE light-trespass limits, dark-sky ordinances, and the equity question almost nobody asks: who gets access to darkness?
