Clock changes linked to health risks: Stanford research reveals permanent solution

A new study by Stanford medical researchers has confirmed long-term hazards to our annual clock change from Standard time to Daylight Saving Time.

The researchers compared the three different time policies — permanent Standard Time, permanent Daylight Saving Time, and the current biannual change practiced by most U.S. states — to see how they could affect people’s circadian rhythms.

Circadian rhythm is the body’s innate, roughly 24-hour clock, which regulates many physiological processes.

Daylight Saving Time will end this year on at 2 a.m. on Nov. 2. The research found that avoiding the change would benefit most people’s health.

In fact, the researchers estimated that permanent Standard Time would prevent about 300,000 cases of stroke per year and result in 2.6 million fewer people h
