Cool, Dark, and Disconnected: The 90-Day Fertility Reset

Code to Conception

Daily micro-protocols for the 90-day miracle window

Day 25 of 90

| November 4, 2025 |

🔬 Pre-Bump Biology  

Heat quietly sabotages sperm by spiking oxidative stress and damaging DNA, while nighttime RF signals and screen pings fracture sleep—the hormonal scaffolding of conception. Today, you’ll lock down two high-leverage moves: protect spermatogenesis over the next 90 days and harden your sleep environment to support eggs, sperm, and implantation.

🧬 Protocol Drop  

Today’s Allopathic Protocol:
For the next 90 days, avoid all saunas and hot tubs. Keep any bath ≤37 °C (98.6 °F). If you or your partner develop a fever ≥38.0 °C (100.4 °F), treat promptly with acetaminophen as first-line (per obstetric guidance). Prioritize a cool bedroom (16–19 °C) and skip heated car seats.

Today’s Holistic Protocol:
Run a bedroom EMF audit tonight: move phones/tablets/watches out of the bedroom (or set to airplane mode ≥2 m from the bed), and turn off or relocate the Wi-Fi router ≥5 m from where you sleep. Use a $10 analog alarm and avoid overnight charging in the room.

📚 Glossary Pop  

Fecundability: The probability of getting pregnant in a single menstrual cycle. When a study reports a fecundability ratio (FR) of 0.60, it means couples were 40% less likely to conceive in a given cycle compared with the reference group.

Forward this to your partner and sync your heat + bedroom audit tonight. Conception is a team sport.
P.S. Tomorrow Teaser
Trade your blue light for moonlight—just twenty minutes of walking and stretching after dinner can calm cortisol and balance reproductive hormones. Then, keep your bedroom at a steady 65–68 °F to deepen sleep, regulate melatonin, and prime your body for conception.
