Why the DC to London red-eye is rough

Seven hours. Five time zones. A 7am landing into a 2am body.

Takeoff is 6–10pm Washington. London is already past 1am. The cabin dinner arrives while London sleeps. You get maybe four hours of useful sleep before the cabin lights come up. You land into a 7am London that feels like 2am to your body. Short flight, sharp jet lag.
