Jet lag is your circadian rhythm fighting your new time zone. Your body wants to sleep, eat, and be alert at the times it expected, not the times locals do. The rule of thumb: 1 day of recovery per time zone crossed. Here is how to compress that recovery and minimize jet lag impact.

Strategy 1: Adjust before you travel

Start shifting your bedtime 30-60 minutes toward your destination time, 2-3 days before flying. Even partial adjustment cuts jet lag duration.

Strategy 2: Use light strategically

Light is the most powerful circadian signal. Going east (Europe from US): Get bright light in the morning at your destination. Avoid evening light. Going west (Asia from US): Get bright light in the evening. Avoid morning light. Light at the wrong times keeps your old rhythm.

Strategy 3: Time meals to local schedule

Eating reinforces circadian timing. Start eating at destination meal times immediately, even if you are not hungry. Avoid heavy late-night meals.

Strategy 4: Use melatonin (carefully)

0.3-1 mg of melatonin taken 30 minutes before your new bedtime can speed adjustment by 1-2 days. See dosage guide. Skip if you take certain medications.

Strategy 5: Get outside

Outdoor daylight is 10,000-100,000 lux. Indoor lighting is 100-500 lux. Outdoor exposure is dramatically more effective at shifting circadian rhythm.

Strategy 6: Manage caffeine and alcohol

Use caffeine to fight afternoon sleepiness at your destination, but cut off 6-8 hours before bedtime. Avoid alcohol on the flight (worsens sleep quality).

Jet lag recovery time estimates

Time zones crossed	Direction	Typical recovery
3-4 zones	Either direction	2-3 days
5-7 zones	East	5-7 days
5-7 zones	West	3-4 days
8 plus zones	Either direction	7-10 days

Why eastward travel is harder

Your circadian rhythm naturally drifts a bit later (toward westward). Pushing it earlier (eastward) fights this drift. Westward travel just lets your rhythm extend, which is easier.
