Like clockwork, Arizonans do fine with standard time

While most of the country turned back their clocks an hour for Daylight Saving Time last weekend and got an extra hour of sleep, we Arizonans greeted their gleeful Facebook posts about it with big yawns.

It’s nothing to boast about; they just got the hour back they lost in the spring, when they whined about being tired.

We don’t go in for this foolishness here.

The Arizona Legislature voted to opt out of Daylight Saving Time in 1968. (The Navajo Nation participates to keep residents across three states on the same schedule.)

Changing sleep patterns, even by one hour, disrupts our body clock, or Circadian rhythm.

The risk of heart attack goes up — some studies say as much as 25% — with the spring time change. (The extra hour of sleep they get back in fall is linked to fewer heart attacks.)

Researchers also have found increases in depression, cluster headaches and strokes associated with the time change.

I mean, why risk it?

Arizona now is two hours behind New York, one hour behind Chicago, on the same time as Denver and an hour ahead of Los Angeles.

So, we have to count off on our fingers to figure out whether it’s too late to call friends on the East Coast or Facetime Aunt Peggy in Ohio.

It’s fine. We can do the math. (Or ask Siri.)

It does mess with our TV schedules as shows on cable TV networks start later. (It’s probably more appropriate that “The Walking Dead” comes on at 10 p.m. anyway.)

And really, more people are watching shows on their own schedules these days.

So, I’ll stay up a bit later to see “The Walking Dead” but sleep soundly while the rest of the country wrestles with whether they reset their alarm clocks correctly.

There are some things you should be able to count on. Like what time it is.
