Detailed Treatment & Solutions
1PRE-TRAVEL ADJUSTMENT
Start shifting sleep 30-60 minutes earlier (eastward) or later (westward) a few days before. Adjust meals and light exposure too.
2DURING FLIGHT
Stay hydrated. Avoid alcohol (dehydrates, disrupts sleep). Limit caffeine. Adjust watch to destination time. Sleep if it's nighttime at destination.
3LIGHT EXPOSURE
Most powerful tool. For eastward travel, seek morning light, avoid evening light. For westward, do opposite. This shifts your clock toward destination time.
4MELATONIN
0.5-3mg melatonin can help. Take at local bedtime at destination. More useful for eastward travel. Consult doctor about timing and dose.
5UPON ARRIVAL
Get outside in natural light. Stay active. Don't nap more than 20 minutes. Go to bed at local time even if not tired. Avoid heavy meals late.
6RECOVERY TIME
Allow one day per time zone for full adjustment. Don't schedule demanding activities first day after long flights. Be patient with your body.
Important: Always consult a healthcare professional before starting any treatment regimen. The solutions above are for educational purposes and may not be suitable for everyone.

Frequently Asked Questions about Jet Lag
Click on a question to see the answer.
Your circadian clock naturally runs slightly longer than 24 hours, making it easier to stay up later (as in westward travel) than go to bed earlier (eastward). Eastward travel requires "advancing" your clock, which is harder. Allow extra adjustment time for eastward trips.
Yes, evidence supports melatonin for jet lag. It's most helpful for eastward travel and when crossing 5+ time zones. Take 0.5-3mg at local bedtime at your destination. It helps signal sleep time to your body. Timing is more important than dose.
