What Is Travel Chronotherapy?
Travel chronotherapy is the careful adjustment of your sleep-wake cycle before, during, and after a long flight. This helps reduce jet lag. For Nigerian travelers going to far-off time zones, like the U.S., Asia, or Australia, this approach can significantly speed up how quickly your body adapts to local time.
Why Nigerians Should Care About Jet Lag
Whether you’re traveling for work, school, or medical reasons, jet lag can:
- Weaken your focus and productivity
- Disrupt your immune system
- Lead to insomnia or digestive problems
- Reduce enjoyment on short trips
How Travel Chronotherapy Works
1. Adjust Sleep Times Gradually
Start shifting your sleep schedule 3 to 5 days before your trip:
- Traveling east (e.g., Nigeria to UAE, India)? Go to bed earlier each day.
- Traveling west (e.g., Nigeria to Canada, U.S.)? Go to bed later each day.
2. Control Light Exposure
Use light carefully:
- Expose yourself to light in the morning at your destination to reset your body clock.
- Avoid bright screens or daylight when it’s nighttime there.
3. Consider Melatonin Supplements
Melatonin, a hormone that helps regulate sleep, can assist you:
- Take 0.5 to 5 mg an hour before sleep (use it carefully and talk to a doctor).
Chronotherapy Timeline Example

Travel day: Sleep on the plane according to Tokyo’s nighttime
During the Flight
- Set your watch or phone to your destination’s time as soon as you board.
