However as a result of flying west primarily lengthens a day, that helps these with longer-running physique clocks beat jet lag sooner. “[But] if somebody’s acquired a shorter-than-24-hour physique clock – consider that as excessive, early morning varieties – they journey a bit simpler to the east,” says Cunnington.
