Most Israelis call it, simply, גֶ’ט-לֶג (jet lag).

But those who work at the Academy of the Hebrew Language would call it by its official Hebrew name, יַעֶפֶת (yah-EH-fet). I haven’t looked into it thoroughly, but I think the Hebrew word somehow merges two others: עַיֵּף (ah-YEF) – tired, and לָעוּף (lah-OOF) – to fly.

The word appears on a list of 63 Modern-Hebrew additions to the language, published by the Academy: one word for each year of Modern Israel’s existence. An alumna of Ulpan La-Inyan forwarded me the list – thanks Judi!
