Daylight Saving Time

Love it or hate it, Daylight Saving Time starts at 2:00 a.m. on March 13. Across the country, people will lose an hour of sleep in exchange for longer days through the summer. Is it worth it?

On one hand, traffic accidents increase for three days following the time change and people become more irritable and groggy upon losing sleep. Absenteeism and heart attacks also increase directly following the time people switch their clocks forward an hour.

Daylight Saving Time: More Trouble Than It's Worth?

If you’re feeling tired due to the daylight savings shift, you’re not alone. One researcher at Washington University says the time change may cause more problems than it solves.

Erik Herzog studies the biological clocks of mammals. He says several studies have shown that daylight saving is hard on us humans, especially the “spring ahead.” Effects like sleep deprivation result in increased traffic accidents for three days after the time change.

Herzog says the effect in the fall is the opposite – there are fewer traffic accidents – but that effect lasts only one day.

It's not easy to adjust to a new time zone or work schedule. Our body has a natural sleep/wake cycle and disruptions to it can lead to more than just feeling tired or exhausted.

Washington University professors Paul Gray and Erik Herzog are studying the biology behind our daily internal clock, or circadian rhythm. Sometimes referred to as the body or biological clock, Herzog defined it as "the entity within the body that synchronizes with an environmental cycle." This is not to be confused with the biological clock some refer to when thinking of a woman's desire to conceive.

Legislation in the Missouri House would permanently adopt Daylight Saving Time as the new Standard Time, but only if 20 other states also agree to do so.

House Bill 340 would create a pact with other states to “eliminate” Daylight Saving Time by renaming it the new “Standard Time.”  And once 20 or more states join the pact, they’ll spring forward one hour and permanently remain there.  It’s sponsored by State Representative Delus Johnson (R, St. Joseph).

Just a reminder to avoid any embarrassing time mixups, Daylight Saving Time ends this weekend.

So, which way to turn your clock? Go by the old adage, "Spring forward, Fall behind" - set those clocks back one hour Saturday night, Nov. 5, so you'll wake up with the right time Sunday.

The shift officially takes place at 2 a.m. local time Sun. Nov. 6.
