Sourced jetlag Q&A · not tied to a trip
Jetlag Coach
Ask any jetlag or sleep question. The coach answers only from a curated research knowledge base, cites the authoritative sources it drew on (CDC, NHS, Sleep Foundation…), and tells you honestly when a question falls outside what it knows. General knowledge — for a plan tailored to a specific flight, build a trip.
