Long-haul flights have become my yearly ritual, and I've noticed that jet lag hits me harder now than in my twenties, even though my sleep habits haven't changed much. A recent trip from New York to Tokyo left me groggy for four days, which makes me wonder if age really does worsen our ability to reset the circadian clock. Sure, I've tried melatonin, timed light exposure, and adjusting my sleep schedule pre-departure, but nothing seemed to shortcut that recovery period. Do you think jet lag gets genuinely harder to shake as we age, or is it just that we accumulate more life stress and less flexible routines? I lean towards it being biological, but I'm open to hearing how others in their forties and fifties have coped on similar routes.
