Health Experts Favor Standard Time Over Permanent Daylight Saving as Congress Debates
CBS News—A renewed national debate over whether to permanently adopt daylight saving time is drawing opposition from health researchers who say standard time is better for human biology. Medical experts argue that permanent daylight saving time would shift light exposure in ways that disrupt circadian rhythms and increase risks including sleep disorders and cardiovascular stress. Airlines have separately flagged logistical complications, noting that permanent DST would significantly complicate international flight scheduling coordination. The debate remains unresolved with Congress having previously considered but not passed legislation.
