Question 1

How long does jet lag last?

Accepted Answer

Roughly one day per time zone crossed when travelling east, and one day per 1.5 time zones when travelling west. A 6-hour eastward trip may take about 6 days to fully adjust.

Question 2

Why is eastward travel harder?

Accepted Answer

Travelling east shortens your day, forcing you to fall asleep earlier than your body expects. Most people find it easier to stay up late (westward adjustment) than to fall asleep early.

Question 3

What is the best way to reduce jet lag?

Accepted Answer

Gradually shift your sleep schedule before the trip, seek bright light at strategic times, stay hydrated, avoid alcohol and heavy meals, and try to eat at local mealtimes immediately.

Question 4

Does melatonin help with jet lag?

Accepted Answer

Many travellers find low-dose melatonin (0.5 to 3 mg) helpful when taken at the target bedtime. It is available over the counter in many countries. Consult a pharmacist if unsure.

Question 5

Can I prevent jet lag completely?

Accepted Answer

For short trips (1 to 2 time zones) jet lag is minimal. For longer trips, you can reduce symptoms significantly with light exposure management and sleep schedule adjustment, but some adjustment period is usually unavoidable.
