Here's a snapshot of the biological insult from international travel. It takes your body over two weeks to fully recover.
It's a big price tag.
One international trip per quarter is a reasonable balance.
Time to recover:
> sleep duration: 2 days
> grip strength: 5 days
> mood: 1 wk
> cortisol: 9 days
> sleep quality: 2 wks
> blood glucose: 2 wks
