Jet lag is caused by a mismatch between a person’s normal daily rhythms and a new time zone. It is a temporary sleep problem that usually occurs when you travel across more than three time zones but can affect anyone who travels across multiple time zones.
If jet lag is preventing you from getting through the remainder of the day, naps are something to consider. If you are going to take a midday snooze, we recommend keeping it under 30 minutes and ideally at least eight hours prior to your bedtime.
