23.10.2026 · 11 Min.

Shownotes

About this episode:

In addition to making you feel a bit jetlagged, the semiannual practice of moving our clocks forward and back can have health impacts. And while many Americans agree that we should "lock the clock," there's a growing debate about whether the clock should be fixed to daylight saving time or standard time. In this episode: Sleep expert Vadim Zipunnikov discusses the biology behind changing clocks and why many scientists—himself included—are on team standard time.

Guest:

Vadim Zipunnikov, PhD, MS, MA, is a professor of Biostatistics at the Johns Hopkins Bloomberg School of Public Health.

Host:

Lindsay Smith Rogers, MA, is the producer of the Public Health On Call podcast, an editor for The Uptake, and the director of content strategy for the Johns Hopkins Bloomberg School of Public Health.
