Frequently Asked Questions
Everything you need to know about jet lag, circadian rhythms, and how to recover faster.
What is jet lag?
Jet lag, also called desynchronosis, is a temporary sleep problem that can affect anyone who quickly travels across several time zones. Your body has its own internal clock (circadian rhythms) that signals when to stay awake and when to sleep. Jet lag occurs because your body's clock is still synced to your original time zone, instead of the time zone where you've traveled.
How long does it take to recover from jet lag?
Generally, it takes about one day for each time zone crossed to adjust. If you travel across six time zones, your body will typically need about six days to fully adjust to the local time. However, recovery time varies depending on the direction of travel and individual factors.
Why is traveling East harder than traveling West?
Traveling East is usually harder because you are 'losing' time, which requires your body to advance its circadian rhythm (go to sleep earlier). Most people find it easier to stay up later (delaying the rhythm) than to go to sleep earlier (advancing it).
How does light exposure help?
Light is the most powerful tool for resetting your internal clock. Exposure to bright light at specific times can help shift your circadian rhythm. For eastward travel, you generally need morning light at your destination. For westward travel, you need evening light.
Should I use melatonin?
Melatonin is a hormone that tells your body it's time to sleep. Taking it at the right time can help signal to your body that it's night in your new time zone. However, timing is critical, and taking it at the wrong time can actually make jet lag worse. Our planner helps you time your melatonin intake correctly.
What are the common symptoms of jet lag?
Common symptoms include fatigue, insomnia, digestive issues, mood changes, and difficulty concentrating. These symptoms usually peak 1-2 days after arrival and gradually improve as your body adjusts.
