Timezone Shift Readiness Tracking

Timezone shift readiness tracking compares HRV, sleep, and energy to your baseline after zone changes—expect temporary dips before judging training off one morning.

Timezone shift readiness tracking compares HRV, resting heart rate, sleep efficiency, and subjective energy to your personal baseline—not population norms—during the five to seven days after crossing zones. Expect temporary suppression; panic-tweaking training off one bad morning misreads travel noise.

Track trends and tag trip direction.

Common questions

  • How long should readiness stay suppressed after travel?

    Often three to seven days depending on zones, direction, and sleep quality. If metrics stay flat beyond ten days, review light timing, evening caffeine, and late naps—not just training load.
