Conquering Jet Lag: A Science-Based Recovery Plan

Conquering Jet Lag: A Science-Based Recovery Plan


Jet lag can ruin the first few days of your trip or make returning home miserable. But with the right strategy, you can minimize its effects significantly.


Understanding Jet Lag


Jet lag occurs when your internal circadian rhythm is out of sync with the local time at your destination. Your body is still operating on your home timezone while the sun and social cues say otherwise.


The Direction Matters


**Traveling East (harder)**: You need to advance your sleep schedule, which is more difficult for most people.


**Traveling West (easier)**: You need to delay your sleep schedule, which aligns better with our natural tendency to stay up later.


Pre-Flight Preparation


3-4 Days Before


Start shifting your sleep schedule:

  • **Going East**: Go to bed 1 hour earlier each night
  • **Going West**: Go to bed 1 hour later each night

  • Day of Travel


  • Choose flights that arrive in the evening at your destination
  • Stay hydrated (avoid alcohol and excess caffeine)
  • Set your watch to destination time immediately

  • Upon Arrival


    First 24 Hours


    1. **Get sunlight exposure** at the right time:

    - Traveling East: Seek morning light, avoid evening light

    - Traveling West: Seek evening light, avoid morning light


    2. **Stay awake until local bedtime** (even if exhausted)


    3. **Eat meals on local schedule** to help reset your circadian rhythm


    Days 2-3


  • Continue seeking light at optimal times
  • Take strategic 20-minute naps if needed (not after 3 PM)
  • Maintain local meal and sleep times strictly

  • The Role of Melatonin


    Taking 0.5-3mg of melatonin 30 minutes before your destination bedtime can help:

  • Signal to your body it's time to sleep
  • Accelerate circadian adjustment
  • Improve sleep quality during adjustment

  • Consult your doctor before using melatonin supplements.


    Recovery Timeline


  • **1-2 time zones**: 1 day to adjust
  • **3-4 time zones**: 2-3 days to adjust
  • **5+ time zones**: 3-5 days to adjust

  • The rule of thumb: one day of adjustment per time zone crossed.


    Special Strategies


    For Short Trips (< 3 days)


    Consider staying on home time if possible. This avoids the double adjustment of going and returning.


    For Business Travelers


    Schedule important meetings for times when you'll be most alert based on your home timezone for the first day or two.
