jetlag
UK: ˈdʒet.læɡ | US: ˈdʒet.læɡ
n. fatigue and disorientation caused by rapid travel across time zones
The word "jetlag" combines "jet" (referring to jet-powered aircraft, symbolizing rapid travel) and "lag" (meaning a delay or falling behind). Coined in the 1960s with the rise of commercial jet travel, it vividly captures the physiological "delay" the body experiences when circadian rhythms struggle to sync with new time zones. The term reflects modern transportation's impact on human biology.
