Your immune age changes with the clock: new study reveals timing matters
NCT ID NCT07169721
First seen Jun 25, 2026 · Last updated Jun 26, 2026 · Updated 1 time
Summary
This study looked at whether the time of day changes a person's 'immune age' — a blood-based score that reflects how well the immune system is aging. Researchers took blood samples from 50 healthy adults aged 20 to 69 at three different times (morning, midday, and evening) on the same day. The goal was to see if the immune age score (called IMMAX) varies with circadian rhythm, which could help improve how we measure immune health.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
What this could lead to
If successful, this could help researchers understand how to measure immune age more accurately by accounting for time-of-day effects.
What could go wrong
This is a small observational study in healthy people, not a treatment trial. The findings may not apply to people with illnesses or different lifestyles.
