The U.S. Senate passed a bill last week that would make daylight saving time permanent. If it gains full congressional approval, the change would take place in fall 2023 and would keep evenings lighter year-round, eliminating the seasonal adjustments of springing forward and falling back to move in and out of standard time.

Many rejoiced. Others pointed out that a two-year shift to daylight saving time was attempted in the 1970s but quickly repealed. The scientific consensus is that standard time — which most of the nation currently observes from November through March — is actually better for our health and circadian rhythms. Erik Herzog, a professor of biology and neuroscience at Washington University, told St. Louis on the Air that the effects of switching to daylight saving time are both immediate and long-lasting. Click here for full story.
