CT Leg: Oppose HB-5877 (Amend to Eastern Standard Time)
Open letter to the Connecticut General Assembly, Government Administration & Elections Committee, submitted 2021 March 4. Citations and visual aids appear at the end.
Dear Honorable Legislators,
Please oppose HB-5877 and recommend its amendment to permanent Eastern Standard Time (75°W). Atlantic Standard Time (60°W) is permanent Daylight Saving Time (DST) at Connecticut’s longitude (73°W). Permanent DST is more harmful than clock change. Only longitudinally correct Standard Time can improve viral immunity with better sleep, can protect school and work start times with morning sunlight, and is pre-approved by federal law.
Scores of organizations representing thousands of scientists/doctors and millions of teachers/parents oppose permanent DST and endorse permanent Standard Time. Among these are the National PTA, National Safety Council, American Academy of Sleep Medicine, American College of Chest Physicians, American College of Occupational & Environmental Medicine, Start School Later, and Society for Research on Biological Rhythms.[AASM][CSC][ESRS][SRBR]
Sleep is essential to viral immunity (including COVID),[Meira][Panda][Ray] and for years the CDC has classified sleep deprivation as an epidemic.[Jin] Springing clocks forward to DST acutely deprives sleep. Leaving clocks forward on DST chronically deprives sleep (at an estimated average of 19 minutes nightly). Artificial delay of sunrise by one hour (such as by DST) manifests as statistically significant increases in accidents, illnesses, diseases (certain cancers up 12–36%), and healthcare costs, and as statistically significant decreases in alertness, learning, productivity, and wages (down 3–5%). It’s not just clock change that harms. Longitudinally correct Standard Time preserves morning sunlight, when human biology needs it most.[AASM][Borisenkov][CSC][Curtis][Gibson][Giuntella][Gu][Juda][Roenneberg][SRBR]
The US Uniform Time Act of 1966 permits permanent Standard Time and forbids permanent DST. Scientific polling shows strong public support to end clock change, with slight preference for Standard Time.[AP] History shows support for permanent DST reverses to strong opposition once its dark mornings are experienced.[BBC][Ripley][Yorkshire]
Permanent DST (AST) would delay Connecticut’s sunrises to 8:21am, and past 8am up to 2.3 months. It would undo the benefits of starting school later, and it would disrupt parents’ work schedules.[Cell][Skeldon] Eastern Standard Time keeps your sunrises before 8am, when most work and school starts,[CDC][Silver] for healthier sleep, mood, alertness, immunity, and productivity.
Please oppose HB-5877 until it is amended to permanent Eastern Standard Time — as is federally pre-approved and is best for health, safety, education, and economy.
