The Study
PBK Modeling of Thyroid Hormone Circadian Rhythm: Elucidating Thyroidal and Extrathyroidal Contributions to Thyroid Hormone Chronobiology
This study is like a computer simulation that tries to mimic how thyroid hormones change during the day. It doesn’t use real people or experiments, so it can’t prove how things work — it just gives ideas about what might be happening.
Analysis score
Maximum 0 for a computational/algorithm study.
Where the score came from
Your body has a clock that helps control thyroid hormones. This study used a computer model to figure out how different parts of the body work together to make these hormones rise and fall at the right times.

Based on clinical experience or non-systematic literature reviews. The lowest level of evidence as they are most susceptible to bias and personal perspective.
Key takeaways
Summary
Based on the study abstract and findings.
- 1Yes, this helps explain how your body keeps thyroid levels in sync with your daily rhythm, which may affect health and longevity.
- 2TSH goes up first in the morning.
- 3T3 follows a bit later.
- 4T4 has a weaker rhythm.
- 5A 3-hour lead in peripheral T4-to-T3 conversion helps explain the timing.
- 6No single process explains all the patterns.

Your thyroid helps control your body's daily rhythms and hormone activity by listening to your brain and telling other hormone glands what to do.
The body’s internal system that turns one thyroid hormone into another isn’t enough on its own to explain the timing and levels of these hormones throughout the day.
Your body's daily rhythm of thyroid hormones isn't caused by just one thing—like the thyroid working on a schedule or how the hormone moves through your blood. It's more complicated than that.
There's a computer model that can mimic how our thyroid hormones rise and fall during the day, and it works by timing how the body converts one hormone into another in different places, with the body's tissues getting a 3-hour head start over the thyroid gland.
