Jet lag from London to Istanbul

Direction matters almost as much as the number of hours. Travelling east, as on this route, means going to bed and waking up earlier than your body is used to, which most people find harder than staying up late — this is why the recovery estimate above runs longer than the raw hour difference. The return trip from Istanbul to London goes the opposite direction and can feel noticeably different even though the hour gap is identical.
To plan around it, check the exact time zone difference between London and Istanbul before you book calls or activities, and see the flight time for London to Istanbul to work out your best arrival window. Landing in the early evening local time and staying awake until a normal bedtime is one of the simplest ways to speed up adjustment on this route.
