Sleep Hygiene for Hormonal Health: The 10-3-2-1-0 Rule

Topic: Lifestyle protocol

Sleep is when your hormones reset.

• Growth Hormone: Surge happens in deep sleep.
• Cortisol: Should be lowest at midnight.
• Insulin: Sensitivity is restored.

If you are sleeping poorly, you cannot balance your hormones. Period. Here is the 10-3-2-1-0 Rule to protect your rest.

10 Hours Before Bed: No Caffeine

• Why: Caffeine has a half-life of 5-8 hours. A coffee at 4 PM means 50% of it is still in your brain at 10 PM.

3 Hours Before Bed: No Food / Alcohol

• Why: Digestion raises body temperature. To sleep, body temperature must drop. Eating late leads to shallow sleep. Alcohol fragments sleep (causes micro-wake-ups).

2 Hours Before Bed: No Work

• Why: Answering emails keeps your brain in “Beta Waves” (Alert). You need to shift to “Alpha Waves” (Relax). Close the laptop.

1 Hour Before Bed: No Screens

• Why: Blue light suppresses melatonin.
• The Swap: Read a book, stretch, or talk to your partner.

0: The Number of Times You Hit Snooze

• Why: Snoozing fragments your REM cycle, leaving you groggier (Sleep Inertia). Get up when the alarm rings.

It is rigid. But so is biology.
