The Truth About Daylight Saving Time

Twice every year, Americans change their clocks—but should we?

Should the United States eliminate Daylight Saving Time? More importantly, if we do, should we adopt permanent Daylight Saving Time or permanent Standard Time?

As Congress debates the Sunshine Protection Act, Karin Johnson, MD discusses the health, safety, and productivity implications of our current system, the scientific evidence behind permanent Standard Time, and what citizens can do if they want to influence future legislation.

In this episode of SleepTech Talk, we sit down with Dr. Karin Johnson, one of the nation's leading sleep medicine experts and advocates for permanent Standard Time, to discuss the growing national debate surrounding the Sunshine Protection Act.

Dr. Johnson explains the science behind our circadian rhythms, why many sleep medicine organizations support permanent Standard Time instead of permanent Daylight Saving Time, and what everyday citizens can do to make their voices heard.

In this episode you'll learn:

• The difference between Daylight Saving Time and Standard Time
• The pros and cons of ending the twice-yearly clock changes
• Why many physicians believe permanent Standard Time is healthier
• How time changes affect sleep, productivity, mood, and public safety
• Where non-healthcare professionals can learn more
• How you can contact your elected officials about the issue

Dr. Karin Johnson serves as Vice President of Save Standard Time and co-chairs the Coalition for Permanent Standard Time, representing leading medical organizations including the American Academy of Sleep Medicine and the National Sleep Foundation. She has also testified before the U.S. Senate regarding the health implications of permanent Daylight Saving Time.
