Is Daylight Saving Time Bad For You? 333
Hugh Pickens writes "According to experts on circadian rhythms, the hour shift in sleep schedule from Daylight Saving Time can have serious effects on some people's health, particularly in people with certain pre-existing health problems. One study found that men were more likely to commit suicide during the first few weeks of Daylight Saving Time (DST) than at any other time during the year, and another study showed that the number of serious heart attacks jumps 6% to 10% on the first three workdays after DST begins. Dr. Xiaoyong Yang, an assistant professor of comparative medicine and cellular and molecular physiology at Yale University, theorizes that shifts in biologic rhythms could trigger harmful inflammatory or metabolic changes at the cellular level, to which these individuals may be more susceptible."

How does this compare to people who travel one time zone over, let alone multiple time zones? Aren't these people (millions) in worse shape?

To solve the problem is VERY simple, but the politicians don't like it. When you move to summer time, move the clocks 1/2 hour forward instead of 1 hour... and then LEAVE them there. No more going forwards and backwards wasting time changing countless clocks and gadgets, and no more bickering about moving the timezone multiple hours forward like the UK had recently just to please some European fascists.

If it's really a health issue, why adjust your sleep schedule to match the changing clock? Can't you simply get up an hour earlier during winter?
DST == Get Your Ass Out Of Bed Earlier (Score:3, Insightful)
Daylight Savings Time is just getting your ass out of bed earlier while pretending you're not. If you like to have light in the afternoon after you get out of work, go to work earlier and leave earlier. You're probably a techie like most of us, so you can probably work flexible hours like most of us. It's different if you're a factory assembly line worker and everybody has to be there at once for the line to roll, or a schoolteacher who's got to be there when class starts. (It's also different if you're a farmer and your cows are going to get up at dawn whatever time the clock says, but since most small farmers tend to also have town jobs, having dawn be later is a real pain.)
So stop messing with everybody else's clocks and get your ass out of bed earlier if that's what you want to do. Real morning people do it anyway (as do people with little kids.) Non-morning people don't want to get up anyway, and often don't. It's only you half-assed morning people who insist on adjusting the clocks to pretend you're not getting up as early as you are.

Sure it's trivial that the number of physical hours of daylight in a 24 hour period doesn't change by changing the clocks, but that's never been the reason to do so. The reason is that people's lives are regulated by clocks. They get to work at 9, and leave at 5, or whatever the hours are. That also means they sleep during the "night" that's defined by those clocks.
The point of daylight savings is that the work hours and night hours are shifted, so that during the period when they are awake and working and living, the amount of daylight is, actually, truly, increased. Also, during the period when the clocks say it's time to sleep, the amount of darkness is increased.
Daylight savings is a great idea, and will continue to be a great idea for as long as human societies are using clocks to synchronize economic activity.
It didn't used to be like that. In medieval or ancient times, people's days started at dawn and ended at sunset, and that was the economic regulator. They didn't have appointments at ten, meetings at two, eight working hours etc. Instead they had longer work days in summer, shorter work days in winter, and meetings around midday, plus or minus a few hours.
I can't believe I have to spell this out on slashdot.
