There are people who complain every time we switch from standard time to daylight saving time (or vice versa), whining about the change affecting their sleep pattern. I'm sorry, I don't get it.
I'll grant you that I don't have a regular sleep pattern, and never have. Some days I'm up early, other days I sleep later. Even when I worked full time, I've never had the kind of schedule that permitted going to bed at a specific time, getting a certain number of hours of sleep, and waking up at the same time every day.
So, I can't relate. But I also wonder whether the people who do keep that kind of schedule have ever changed it because they stayed up an extra hour to watch a football game on a Sunday night, or went out to a concert on a Tuesday night. What about the people who have babies that awaken them at any hour of the night? What about adults awakened by nightmares or snoring partners or bathroom visits? Do the rigid sleep schedulers never visit another time zone?
It's not like we had to move the clock back thirteen hours -- that would be a valid reason for lots of confusion. You'd wake up and not know if it's morning or evening. I know what that's like, having done enough morning radio plus afternoon naps to sometimes wake up twice in the same day in the dark and have to take a few minutes to find my bearings. But it took minutes, not an entire day.
Even worse are the people who complain about the one-hour time change when they get to work on Monday. Really? Your body couldn't adjust over the course of 24 hours? Perhaps you should consult a physician.
But don't make that appointment too early, or it'll throw off your entire month.
