Imposing Permanent Daylight Savings Time Is Like Imposing Permanent Jet Lag

(p. A19) . . . when the U.S. Senate recently passed a bill to make daylight-saving time permanent, sleep experts became more alarmed.

Legislators picked the wrong time, they say.

Our internal clocks are connected to the sun, which aligns more closely with permanent standard time, says Muhammad Adeel Rishi, a pulmonologist and sleep physician at Indiana University. When the clocks spring forward, our internal clocks don’t change but are forced to follow society’s clock rather than the sun. DST is like permanent social jet lag.

Dr. Rishi is one of the authors of a 2020 position statement from the American Academy of Sleep Medicine, a professional society, supporting making standard time—not daylight-saving time—permanent.

. . .

One of the big problems with permanent DST, objectors note, is that in the winter the sun will rise later and many schoolchildren will be walking to school in the dark.

On the western edge of the eastern time zone in Indiana, for instance, the sun won’t rise in the winter until about 9 a.m., notes Dr. Rishi. “You’re basically putting these kids two hours off from their circadian biology,” he says.
