What's Worse Than Setting Clocks Back an Hour? Permanent Daylight Savings Time

'It's that time again,' writes USA Today, noting that Sunday morning millions of Americans (along with millions more in Canada, Europe, parts of Australia, and Chile) 'will set their clocks back an hour, and many will renew their twice-yearly calls to put an end to the practice altogether...'

Experts say the time changes are detrimental to health and safety, but agree that the answer isn't permanent DST. 'The medical and scientific communities are unified... that permanent standard time is better for human health,' said Erik Herzog, a professor of biology and neuroscience at Washington University in St. Louis and the former president of the Society for Research on Biological Rhythms...

Springing forward an hour in March is harder on us than falling back in November. The shift in spring is associated with an increase in heart attacks, and car accident rates also go up for a few days after, he said. But the answer isn't permanent daylight saving time, according to Herzog, who said that could be even worse for human health than the twice-yearly changes. By looking at studies of people who live at the easternmost edge of time zones (whose experience is closest to standard time) and people who live at the westernmost edge (more like daylight saving time), scientists can tell that health impacts of earlier sunrises and sunsets are much better. Waking up naturally with the sun is far better for our bodies than having to rely on alarm clocks to wake up in the dark, he said.
Herzog said Florida, where [Senator Marco] Rubio has championed the Sunlight Protection Act, is much less impacted by the negative impacts of daylight saving time because it's as far east and south as you can get in the U.S., while people in a state like Minnesota would have much more time in the dark in the morning.

The article also reminds U.S. readers that 'No state can adopt permanent daylight saving time unless U.S. Congress passes a law to authorize it first.' Nevertheless...
Oklahoma became the most recent state to pass a measure authorizing permanent daylight saving time, pending Congressional approval, in April. Nineteen other states have passed laws or resolutions to move toward daylight saving time year-round, if Congress were ever to allow it, according to the National Conference of State Legislatures...

Only two states and some territories never have to set their clocks forward or backward... [Hawaii and Arizona, except for the Navajo Nation.]
