🔬 Pre-Bump Biology  

Evening light and kitchen plastics both hit the same bullseye: oxidative stress and hormone noise that torpedo egg quality, sperm integrity, and implantation. Tonight we protect melatonin (your ovary/testis antioxidant switch). Today we slash BPA (an estrogen-mimic tied to fewer oocytes and lower sperm counts). Two simple moves, one powerful fertility lift.

🧬 Protocol Drop  

Today’s Allopathic Protocol:
Order urinary total BPA (first-morning void) at Day 0 and Day 30. Act until you’re < 11.5 ng/L (EEA HBM-GV). Implement a kitchen purge: no cans, no polycarbonate (#7 “PC”), no heating plastic; replace with glass/steel/ceramic. Re-test at Day 90.

Today’s Holistic Protocol:
From 8 p.m. (≥3 h pre-bed), keep melanopic EDI ≤10 lx (aim ≤5 lx). Wear high-density blue-blocking glasses (mDFD ≥ 1), set all screens to max warm at the lowest usable brightness, and use ≤2200 K lamps below eye level. During sleep, keep the bedroom ≤1 lx mEDI; next morning get ≥250 lx mEDI outdoors for 30–60 min.

📚 Glossary Pop  

Melanopic EDI (mEDI): A way to measure how much biologically active blue-weighted light hits your eyes. Lower mEDI in the evening preserves melatonin (sleep and reproductive antioxidant hormone); higher morning mEDI anchors your body clock.

Text your partner: “Blue glasses on at 8. Kitchen plastics out by dinner.” Stack these and own your 90-day window.
P.S. Tomorrow Teaser
Heavy breakfast before 10 a.m.; glass and steel only in your kitchen. Together, they stabilize hormones all day long.
