|
|
Because the cabin pressure of the plane causes drowsiness.
|
|
|
Because flying at high altitudes causes you to breath thinner air making it difficult to get oxygen into your blood stream.
|
|
|
Because internal circadian rhythms do not match external environmental cues.
|
|
|
Because moving at high speeds causes your body work harder to pump blood which can induce tiredness.

Detailed explanation-1: -Your body has its own internal clock, called circadian rhythms. They signal to your body when to stay awake and when to sleep. Jet lag occurs because your body’s internal clock is synced to your original time zone. It hasn’t changed to the time zone of where you’ve traveled.
Detailed explanation-2: -This changing rate of activity over each 24-hour period is called the circadian rhythm (’circadian’ means approximately one day). Travelling to a different time zone disrupts the circadian rhythm. Lack of sleep before and during travelling can also contribute to jet lag.
Detailed explanation-3: -During jet lag, the various oscillatory components of the circadian system are likely out of phase with the central clock in the SCN and consequently with each other. This disorganization of the circadian system leads to a cluster of symptoms including sleep disturbances and suboptimal cognitive performance.
Detailed explanation-4: -When you travel across more than two time zones by plane, your body’s “internal clock” (or circadian rhythm) needs time to adjust to the new sleep and wake cycles at your destination. Jet lag is a type of circadian rhythm sleep disorder.
