Permanent Daylight Saving Time: Doctors Warn of Health Risks

Five prominent medical organizations have called for permanent standard time, directly opposing the House's Sunshine Protection Act, which favors permanent daylight saving time (DST). The medical community emphasizes that standard time better aligns with the body's natural circadian rhythm, synchronized by morning light. Permanent DST, conversely, would shift sunrise later by social convention, leading to widespread "social jet lag." This condition, defined as a discrepancy between biological and social time, is associated with serious health risks including metabolic disorders, cardiovascular strain, and mood disturbances. This is not the first time the US has considered permanent DST; a similar measure enacted in 1974 was repealed within a year due to negative public reaction to darkened winter mornings. While the current bill has bipartisan support, the medical consensus favors permanent standard time for public health and safety.
