2 NFL Teams Travel to Australia as Sleep Scientists Study Jet Lag

Two National Football League franchises, the San Francisco 49ers and the Los Angeles Rams, are in Australia this week for a scheduled matchup, and sleep researchers are treating the trip as a rare natural experiment in circadian disruption, according to reporting cited by SFist.

Why are sleep scientists interested in an NFL game?

Elite athletes rarely cross this many time zones in a single week under controlled, observable conditions. A cross-continental road trip involving two full rosters, coaching staffs and support personnel gives researchers a dataset that laboratory studies cannot replicate: real competitors performing under real stakes after real long-haul travel, per the report cited by SFist. The interest is not in the football result itself but in what happens to the body's internal clock when it is pushed across a large number of time zones in a short window.

What exactly will researchers be able to measure?

The report frames the trip as a chance to observe how long-haul travel and the resulting circadian disruption affect performance markers in professional athletes, though specific data-collection methods were not detailed in available reporting. In general circadian science, researchers typically look at sleep timing, reaction speed and recovery markers before and after a time-zone shift — the categories of interest flagged in coverage of this matchup.

What does the travel disruption look like for the two teams?

Rough shape of the trip

• Departure phase: Both organizations leave North America for Australia in the days before kickoff.
• Adjustment window: Players and staff have a limited number of days on the ground before the game to adjust sleep and training schedules.
• Game day: The 49ers and Rams compete on Australian soil, the event drawing scientific attention specifically because it is unusual, per the cited report.
• Return phase: Teams travel back across the Pacific afterward, adding a second disruption to the same data window.

That sequence — departure, short adjustment, competition, return — is what gives researchers two distinct disruption points to study rather than one.

Why does this matter beyond one NFL week?

Jet lag and travel fatigue are recurring concerns across international sport, but researchers rarely get a matchup involving two full professional teams making the same extreme trip at the same time. That symmetry — two teams, one shared travel shock, one shared kickoff — is what the cited report describes as the draw for scientists rather than fans or bettors.

What happens after the game?

Available reporting does not specify a publication timeline, a research institution, or named scientists attached to the study, so it remains unclear when — or whether — formal findings will be released. HTT News World Desk could not independently verify additional details beyond what is described in the cited report and will follow up if researchers publish results.
