For a game in Melbourne on Thursday night, the San Francisco 49ers traveled a week before the game while the Los Angeles Rams will fly out the day before. Dr. Cathy Goldstein of the University of…

So when we cross time zones, just because the clock on the wall changes in our destination, it doesn't mean that our body clock changes immediately.

And that's because we have an internal timing system, our biological clock called the circadian rhythm.

So what happens is when you travel to a new time zone and Your body is trying to align.

And during that alignment process, you end up with a misalignment between your internal circadian rhythm and external time.

This results in sleep disruption, problems with performance, problems with digestion, metabolism.

And what's the time zone change from Melbourne to L.A.? If it's 17, they're going to need at least 17 days to fully align.

And it's not just that internal circadian misalignment with the time in Melbourne.

while they're training and trying to recover and optimize themselves for the game the week ahead.

What the Rams are doing, so this is in complete contrast to the 49ers, they're going out right before.

So what that means is their body clock is going to remain aligned to L.A. time, Leading up to the game, they're going to be sleeping normally, training normally.

And I personally think this is a much better strategy to address this massive change in time zones.

10.35 a.m. in Melbourne is around 5 p.m., we said, right, on L.A. time and Pacific Standard Time.

So the late afternoon, early evening, that is the body's time of peak physical performance.

So we know and they've actually studied this based on Monday night football.

So if they stay on that Pacific Standard Time with no attempts to convert, they are giving themselves the best opportunity to perform at the highest level.

They did the same thing where they just flew over the night before, played the game, and it was the right strategy because they won the game over the Jacksonville Jaguars that week, and then they came straight back.
