A long flight can be completed successfully, but the traveler's body can continue to function according to the country's schedule from which it is headed.
This situation is known as wet jet and particularly affects people who travel through several time zones.
According to the U.S. Centers for Disease Control and Prevention, CDC, rapid change in hours can cause insomnia, sleep during the day, fatigue, and difficulty in focusing.
The main reason is noncompliance between the biological clock of the body and the local destination schedule.
The CDC recommends that travelers try to adjust sleep schedules gradually a few days before the trip.
Exploration to natural light at the right time is another factor that can help the body adapt.
During flight, hydration and restriction of alcohol can help prevent symptoms from getting worse.
After arriving, experts recommend avoiding long sleep during the day, while short holidays can help cope with fatigue.
However, the ideal time for exposure to light varies according to the direction of travel and the number of time zones passed.
For short business trips, the full adjustment to destination schedule may not always be necessary.
Sleep planning can be as important as hotel booking, especially when the traveler has appointments or activities immediately after his arrival.
