Moving the clock forward or backward by an hour may not seem like much, but research shows it disrupts circadian rhythms and eating patterns.
In the days following daylight saving changes, people sleep less deeply and experience more fragmented rest.
There is also an uptick in late-night snacking, likely due to hormone shifts that regulate appetite.
Public health researchers advocate for abolishing daylight saving altogether, noting its contribution to grogginess, poor nutrition, and increased car accidents.
