Why Does Jet Lag Occur? Why Is Jet Lag Worse

Question

Examlex · Accepted Answer

The Answer is Jet lag occurs when our internal body clock, also known as the circadian rhythm, is disrupted due to rapid travel across multiple time zones. Our bodies are naturally programmed to follow a 24-hour cycle, and when we travel quickly across time zones, our internal clock becomes desynchronized with the external environment.

Flying eastward typically causes worse jet lag than flying westward because traveling east means losing time, which goes against our body's natural circadian rhythm. This can lead to a more severe disruption of our internal clock, as it becomes more difficult for our bodies to adjust to a shorter day. In contrast, flying westward means gaining time, which is more in line with our natural body clock and can be easier for our bodies to adapt to.

Additionally, the direction of travel affects the timing of exposure to natural light, which is a key factor in regulating our circadian rhythm. When traveling east, we may be exposed to light at times when our body is not naturally expecting it, causing further disruption to our internal clock. Flying west, on the other hand, may align more closely with our body's natural exposure to light, making it easier for our internal clock to adjust.

Overall, jet lag occurs due to the disruption of our internal body clock caused by rapid travel across time zones, and it is typically worse when flying eastward due to the mismatch between our natural circadian rhythm and the direction of travel.
