Sleep disturbance occurs, with poor sleep upon arrival or sleep disruptions such as trouble falling asleep (when flying east), early awakening (when flying west), and trouble remaining asleep.
Scientists define jet lag as the effect on the human body of traveling across different time zones. Our bodies have biological clocks programmed into almost every cell in the body, according to ...

Jet lag disorder – Jet lag disorder is a type of circadian rhythm sleep disorder that results from rapid travel across multiple time zones. Individuals experiencing jet lag may encounter symptoms such as excessive sleepiness, fatigue, insomnia, irritability, and gastrointestinal disturbances upon reaching their destination.
A circadian rhythm is an entrainable, endogenous, biological activity that has a period of roughly twenty-four hours. This internal time-keeping mechanism is centralized in the suprachiasmatic nucleus (SCN) of humans, and allows for the internal physiological mechanisms underlying sleep and alertness to become synchronized to external environmental cues, like the light-dark cycle.

Jet lag is what happens when you travel to a different time zone “at a faster pace than the body is capable to adapting,” said Dr. Richard Dawood, a travel medicine specialist at Fleet Street ...
The most easily observed of these is the propensity for sleep and wake; thus, people with non-24 experience symptoms of insomnia and daytime sleepiness (similar to "jet lag") when their endogenous circadian rhythms drift out of synchrony with the social/solar 24-hour day, but they conform to a conventional schedule. Eventually, their circadian ...
