When you are travelling abroad you pass through new time zones. After you landed you would feel very tired and very sleepy. This is due to a condition named jet lag. Do you know why you feel tired and sleepy when crossing time zones? It is mainly due to the disruption in the circadian rhythm. You have a biological clock inside which regulates you sleep and wakefulness. When you cross time zones your internal clock and the external time becomes desynchronized. So, your body needs to get on the rhythm of the new time zone. This makes you tired.
