Multiple independent tier-1 and primary sources (AP, Harvard, Nature, PMC review, JHU) report that the spring clock change is associated with increased heart attacks, strokes, cardiac events, mental health episodes and car crashes, so the claim's core is supported; the sources describe these as modest or small associations rather than large effects, which the claim's wording does not contradict.

A guest makes this claim. Listeners heard it, so it counts against the post, and on the guest's own record.

What was said

… And when Trump is saying there's health issues associated with the time change, he's correct, but that is because we strip away that hour in spring. That's where we see the increase in heart attack and stroke, cardiac events, mental health episodes, car accidents, all of those things. So that is correct, but that is because we're changing the time and taking an hour from people.

What we found

Supports. AP reports studies found an uptick in heart attacks and strokes right after the March time change, and that daylight saving time can usher in sleep trouble.[1]

Supports. Nature's review links clock shifts to modest elevations in cardiovascular events, traffic accidents and markers of mental dysfunction, most pronounced after spring-forward.[4]

Supports. A 2026 comprehensive review reports spring DST transitions are associated with increased cardiovascular events, traffic accidents, and short-term increases in psychiatric symptoms and suicidality.[2]

Supports. Johns Hopkins (2026) reports higher rates of vehicle crashes and a small elevation in heart attack risk in the week after the spring change; AAMC reports increased heart attacks and car crashes after spring forward.[3][5]

Context. The effects are described as small or modest in several sources, and some outcomes (e.g., mental health) rest on fewer studies; the claim does not state magnitudes, so this is a context note rather than a contradiction.[4][6]
