Lagging reactions is one of the downsides of long-distance travel. While crossing multiple time zones has its advantages in visiting new countries and exploring other parts of the world, feeling disoriented and overwhelmed after traveling for too long can spoil the fun (at least for a few hours or days).

Fatigue and sleep disturbance are the most important annoyances for people suffering from jet lag. But that’s not all. A recent study led by Jonathan Johnston of the University of Surrey suggests that changes in our daily routine can disorientate the body’s internal metabolism.

The study explored how even the smallest temporary shifts can affect the body. Jet lag is often associated with long commutes and multiple time zone shifts. But sometimes even minor events can cause us to feel discord, albeit temporarily.
Why does jet lag happen?
The human body works on the basis of a circadian rhythm, which regulates sleep patterns, hormone production, and even general metabolism. It is controlled by the suprachiasmatic nucleus, a tiny region of the brain that responds to environmental cues such as light and dark cycles to adjust the body’s rhythm accordingly.

Research results:
The study was conducted on 14 participants (8 men and 6 women), who were asked to shift their daily routine by five hours. The research team monitored their daily routine, including meal times, lighting and sleep schedules. Their metabolism was recorded, including the time it takes the body to process food, changes in blood sugar and fat levels, and energy burn.
The results showed that even a five-hour change in daily routine can affect a person. Slow digestion, changes in blood sugar and a shift in metabolism have been reported. Participants also showed less efficiency in generating heat from the food they consumed.

Can the body adapt to the new schedule?
However, their bodies adapted to the new schedule within 48-72 hours, showing remarkable flexibility. This further explains how people adjust to the new time zones over several days. But the results showed the impact of frequent time shifts on health and how it can affect daily metabolism. While the body adapts to it, it may not be ideal to put it through the ordeal multiple times.
