This image captures a young woman sitting on the floor of an airport with her head in her hand, visibly tired and overwhelmed—classic signs of jet lag. Jet lag is a temporary sleep disorder that occurs when the body’s internal clock is out of sync with a new time zone, especially after long-haul flights crossing multiple time zones. Symptoms include fatigue, insomnia, headaches, poor concentration, and digestive discomfort. The image effectively represents the physical and mental toll jet lag can take on travellers, especially during international travel.
