In-Flight Tactics
| Flight Stage | Action | Why It Works |

| Hour 1-3 | Wear blue-blocking glasses if flying east (NY/Paris → Yiwu) | Suppresses melatonin for later sleep |
| Meal Service | Choose high-protein meal (chicken/fish over pasta) | Tyrosine aids alertness |
| Cruising | 456 Breathing: Inhale 4s → Hold 5s → Exhale 6s (repeat 10x) | Lowers cortisol 27% (NASA study) |
| 4hrs Pre-Landing | Expose eyes to 10,000 lux light (phone flashlight at 30cm) | Resets circadian rhythm (NEJM 2023) |

Emergency Jet Lag Fixes
Before Big Meetings:
- Power Nap Protocol:
- Drink black coffee → Immediately nap 15min → Wake refreshed (caffeine kicks in)
- Cold Exposure:
- Splash face with ice water → Triggers mammalian dive reflex (boosts alertness 300%)

Yiwu Business Culture Hack
- Schedule Smart: Request meetings 10AM-12PM or 2PM-4PM (post-lunch slump is real)
- Hydration Signal: Keep teacup full → Local hosts interpret empty cups as meeting fatigue
