Jet lag comes from your circadian rhythm lagging behind local time. You can't eliminate it, but you can cut recovery from 7 days to 2. The secret is light, food, and caffeine timing — not just sleep.
Key Tactics
Shift your sleep 1-2 hours toward destination time 2-3 days before flying. On arrival, stay awake until local bedtime even if it hurts. Get bright morning sunlight immediately — it's the strongest circadian cue. Skip alcohol on the plane (it wrecks sleep quality).

What to Avoid
Avoid long naps the first day (keep under 30 minutes). Don't use melatonin before checking current research — low doses (0.5mg) at destination bedtime help, high doses often backfire. Avoid heavy meals at the wrong time — eat according to local schedule.
Frequently Asked Questions
Does the 'Jet Lag Rooster' app help?
Yes — Timeshifter and similar apps give personalized light/dark schedules. Backed by research and effective if followed.
Is melatonin actually useful?
At low doses (0.3-0.5mg), yes — especially for eastbound travel. At high doses (5-10mg), results are inconsistent. Consult a doctor for personalized advice.
How long does jet lag last?
Typically one day of recovery per time zone crossed. Eastbound is harder than westbound.
