🔬 Pre-Bump Biology  

Cut the oxidative hits, then add a redox-boost. Disinfection by-products (HAAs/THMs) and metals can sap sperm mitochondria, dent oocyte yield, and trim implantation odds. Meanwhile, a light resistance circuit (RPE 5–6) improves insulin signaling and antioxidant defenses. Together, you protect egg/sperm quality and nudge implantation in your favor.

🧬 Protocol Drop  

Today’s Allopathic Protocol:
Install an NSF/ANSI-53 carbon block plus NSF/ANSI-58 RO at your kitchen tap. Drink/cook 2–3 L/day from this source. Make all coffee/tea with it. Keep hot showers short and well-ventilated to curb inhaled THMs. Replace cartridges on schedule.

Today’s Holistic Protocol:
Do a 20-minute light strength circuit (RPE 5–6), 5–6 days/week, 1–6 hours after waking. Two to three rounds, 45 s work / 15 s transition: body-weight squats → banded hip hinge → split squats → banded rows → glute bridge → lateral band walk → Pallof press → dead-bug. Stay sub-maximal; finish non-exhausted.

📚 Glossary Pop  

Haloacetic acids (HAAs): A family of chlorine by-products formed when disinfectants react with organic matter in water. At common exposure levels they’re linked to lower oocyte yield and reduced implantation/live birth proportions in IVF cohorts; carbon block + RO meaningfully lowers intake.

Tag your partner: one installs filters, the other runs the circuit. Two levers, one goal—conception.
P.S. Tomorrow Teaser
You can’t optimize what you don’t measure—or unwind what you never relax. Tomorrow we’ll pair the environmental audit (tap water, radon, hidden disruptors) with a nightly progressive muscle relaxation ritual that trains your nervous system to release before conception even begins.
