beating jet lag before you even board

cdc's own travel guidance, minus the medical hedge language. three days out, not zero

Three days out: start shifting sleep and meals toward destination time

even 30-60 min a day adds up, way less brutal than trying it in one jump

Two days out: get bright light at the time that matches destination morning

if you're flying east this is the annoying one, you're chasing light before your body wants to be awake

Day of: set your watch to destination time the second you board

sounds silly but it starts the mental shift immediately

On the plane: time meals to destination schedule, not departure city time

On the plane: sleep only if it's nighttime at your destination

napping through a daytime-arrival flight just moves the problem to later

First day: get outside within a few hours of landing

light exposure resets the clock faster than anything else, including melatonin

First night: melatonin at destination bedtime, not before

taking it too early just makes you groggy at the wrong time

First 48 hours: eat on local schedule even if you're not hungry yet

your stomach lags behind your brain by about a day

Short trips under 2 days: don't bother adjusting at all

stay on home time, it's less disruptive than a fake reset for 36 hours
