Jetlag Control

A precise plan for light exposure, sleep, caffeine and meals — reset your body clock before or after the flight.

Step 1 — Flight route

Enter times in the local time of each airport.

Step 2 — Your profile (optional)

Step 3 — Adaptation strategy

How does jetlag control work?

Based on your flight route, travel direction and chronotype, we generate a daily schedule of light exposure, sleep, caffeine, meals and melatonin that gradually shifts your body clock to the new time zone. This is general chronobiology guidance, not medical advice.
