I’m no fan of arbitrary adjustments to time, but I’m actually somewhat more ambivalent about Daylight Saving Time (note: “saving,” not “savings”) than a lot of people I know. But I should probably rewind a bit.
I’m an insomniac. Anything that messes with my ability to get enough sleep is unwelcome in my life. Changing the clocks by an hour twice a year always messed me up pretty badly, to the extent that I’d sometimes even fall asleep at work during the first week of DST. For the same reasons, I’m pretty badly affected by jet lag, and whenever I travel across time zones I now try to prepare a few days early so I’m already better-adjusted to the new time before I even arrive.
So a few years ago when DST started I tried something new: I didn’t reset my clocks. I’d been going through a rough stretch with the insomnia and it was just One More Thing to deal with, and I announced to my manager at work that I was probably just going to be late for a week, since the alternative was worse.
A curious thing started that week, though: I had quit using an alarm the week before in an attempt to reset my body clock, and I kept not using it that week. I slowly came into line with the rest of the world, and I never turned the alarm back on. And for the most part, years later, I still haven’t turned the alarm on for daily use.
My sleep cycles are more regular without an alarm clock than they ever were with one. I now have a so-called “dawn simulator,” an alarm clock that uses light instead of noise, and I use it when I have to get up earlier than usual (for me), but my mornings are almost entirely free of wretched beeping. Not everybody can go without an alarm, but it has worked better for me than any other single approach to sleep regulation.
Anyway, back to Daylight Saving: by common practice and law, we all agree to set our clocks forward by an hour in the Spring and set them back an hour in the Fall. What this means for the alarm users among us is a lost hour of sleep and several days of, well, jet lag. What happens when you’re jet lagged? Your reactions are slower, your mind is fuzzier, you’re a little bit clumsier, and you probably have more coffee than usual in an effort to perk up. This is supposed to save energy, but it turns out that the difference is within the margin of error, and all the best guesses were estimated anyway. So if we’re not actually saving energy, why are we losing sleep over it?
