 Context examples 

If rhythms in different organs are out of sync, do plants suffer from a kind of internal jet lag?

(Plants can tell time even without a brain, University of Cambridge)

This cycle runs autonomously in the cell, causing jet lag during travel, but can be regulated to retrain to changes in the light cycle.

Neurons in the brain that produce the pleasure-signaling neurotransmitter dopamine also directly control the brain's circadian center, or body clock — the area that regulates eating cycles, metabolism and waking/resting cycles — a key link that possibly affects the body's ability to adapt to jet lag and rotating shift work, a new University of Virginia study has demonstrated.
