jet lag is an expression in English that does not have a defined translation in the Portuguese language, but is used to characterize a "time imbalance" caused in an individual when changing time zones.
In some cases, the word jet lag can be translated as a synonym for insomnia.
Etymologically, the word jet lag is formed by the union of terms jet ("jet" or "airplane" in English) and lag ("delay" or "delay" in English). It represents a change in a person's biological rhythm when making long international trips, characterized by physical and psychological problems. Among the main disorders is the disturbance in the sleep cycle, with changes in hormones, especially hydrocortisone.
O jet lag it happens because the human body is normally adapted to having a certain routine in a 24-hour period (waking up, eating, studying, having dinner, sleeping, etc.). This routine is known as the "Circadian Rhythm" and when a person drastically changes the ambient time zone, it breaks the sync of the body, making it quite confused.
Nausea, irritation, fatigue, insomnia, constipation, and other physiological problems can be some of the symptoms caused by jet lag.
