Daylight saving time is about to start, and an interesting thing that you might not realize is how such a small shift in our time can have a large impact on our body clock and our health. These negative impacts of daylight saving time even cost us real money in lost productivity.
DST starts at 2 a.m. (the clock gets turned forward to 3 a.m.) on the second Sunday in March and ends at 2 a.m. (the clock gets turned back to 1 a.m.) on the first Sunday of November. That means our clocks spring forward an hour this Sunday, March 9. This is the "bad" time change, since it means we lose an hour of sleep over night.

It was enacted during World War I to decrease energy use. Benjamin Franklin first advocated for the practice in 1784 because he noticed that people used candles at night and slept past dawn in the mornings. By shifting time by an hour during the summer, they would burn fewer candles and not sleep through the morning sunlight.
The debate still rages as to whether this time-switch does save energy, but along the way we've seen signs that it has negative effects on our health and the economy.
Surprising Health Impacts
Transitions associated with the start and end of DST disturb sleep patterns and make people restless at night, which results in sleepiness the next day. This is true even during a "fall back" period, since when we fall back, we might have trouble adjusting to going to sleep "later" after the time change.
One pretty obvious study in Neuroscience Letters found that when people were transitioning their schedules after "springing forward," the quality of their sleep decreased and they slept an average of an hour less per night.
The resulting sleepiness leads to a loss of productivity and an increase in "cyberloafing," in which people muck around more on the computer instead of working. That finding was from a 2012 report in the Journal of Applied Psychology.
During the first week of DST (in the late winter) there's a spike in heart attacks, according to a study in the American Journal of Cardiology (and other previous studies). That's because losing an hour of sleep increases stress and provides less time to recover overnight. The opposite is true when we gain an extra hour of sleep. The end of daylight saving time causes a decrease in heart attacks.
Deadly car crashes decrease during DST (the spring, summer, and fall), because it's more likely to be light out when there are more people on the road, for example going to and returning from work or school.
But that's not likely true on the Monday after DST starts. Groggy people driving in the dark are more prone to accidents. Getting some extra sun in the morning, going to sleep earlier, or sleeping in slightly could help.
Research has found that having DST all year round could decrease deaths from traffic accidents even more—saving up to 366 lives, according to a 2004 study in the journal Accident Analysis & Prevention.
Accidents at work happen more often and are more severe after springing forward, according to a study of miners published in the Journal of Applied Psychology in 2009.
A study published in 2008 in the journal Sleep and Biological Rhythms found an uptick in suicides in Australian men during the first weeks after daylight saving time.
The impacts of DST are likely related to our body's internal circadian rhythm, the still-slightly-mysterious molecular cycles that regulate when we feel awake and when we feel sleepy, as well as our hunger and hormone production schedules.
Light dictates how much melatonin our bodies produce. When it's bright out, we make less. When it's dark, our body ramps up synthesis of this sleep-inducing substance. Just like how jet lag makes you feel all out of whack, daylight saving time is similar to scooting one time zone over for a few months.
The problems with DST are the worst in the spring, when we've all just lost one hour of sleep. The sun rises later, making it more difficult to wake in the morning. This is because we reset our natural clocks using the light. When out of nowhere (at least to our bodies) these cues change, it causes major confusion.
Like anytime you lose sleep, springing forward causes decreases in performance, concentration, and memory common to sleep-deprived individuals, as well as fatigue and daytime sleepiness.
Night owls are more bothered by the time changes than morning people. For some, it can take up to three weeks to recover from the sleep schedule changes, according to a 2009 study in the journal Sleep Medicine. For others, it may only take a day to adjust to this new schedule.
That's Not All
All of these impacts have economic costs too. An index from Chmura Economics & Analytics, released in 2013, suggests that the cost could be up to $434 million in the U.S. alone. That's an estimated total of all of the health effects and lost productivity mentioned above.
Other calculations suggest this cost could be up to $2 billion—just from the 10 minutes twice a year that it takes for every person in the U.S. to change their clocks. (If you calculate 10 minutes per household instead of per person this "opportunity cost" is only $1 billion.)

I do not understand why we still do this. There is no good reason for it. And by that, I mean "I like an extra hour of daylight at night" is not a good enough reason to offset all the negative affects.
Yeah, it was great having daylight until almost 8:00 o'clock last night, but then, we had longer darkness this morning when everyone has to get up and get to work and school.
It needs to be abolished. LIVES are not worth it. And economically, it's not worth it.

I would like it much better if we made the change around the second weekend in April. Going from sunrise at 6am. to sunrise at 7am. wouldn't seem so bad. (At least, to me.)
Without DST, Summer would be awful. I couldn't imagine sunrise at 5:20am. and sunset at 7:40pm. in June.

That would suck. JMHO.
Why? Why is that different than any other time of the year? Heck - I don't care, leave it ahead. Just stop changing it. Pick a time!

Old Indian proverb
"Only a white man would cut a foot off the bottom of a blanket, sew it to the top, and then tell you that it's a longer blanket."
A side funny...I had a customer relate a conversation she overheard at a local beach.
Woman A: We change time this weekend.
Woman B: Yes, I can never remember if I change the clocks forward or back.
Woman A: All I know is that the sun rises in the west starting then.

I cannot find the cartoon, but it was back in the 70's, of Nixon cutting a blanket and sewing back. What I found is it was done by Pat Oliphant.
I don't under stand the logistics of it. We may have an extra hour of sun, but we have bed time an hour earlier.

The energy savings idea is:
In the summer with Daylight Savings people will come home and use lights less. With DST you get home and turn on your lights an hour later.
In the morning you will be asleep anyway. With DST sunrise could still be at 5:30am, without DST at 4:30am. Most people will sleep during the light hours in the morning.
I like DST and wish they would just leave it this way all year round. As it is we are only on standard time for 4 months anyway. I love having it light later in the evening so I can go out after work and not feel like it's bedtime at 7:00pm.

Before kids I would walk when I got home and DST was good for that. I don't care if they keep it all year long. I just don't see why they have to switch it up twice a year.

When the kids still have to go to bed so they can get enough sleep for school, it's difficult to get them to go to sleep when it is still light outside at 8:30 and hard to get them up when it's still black as pitch in the morning.

But I don't want sunrise at 4:00am.
And I don't want sun set at 6-7pm in the summer! When it's nice out, I want to be outside. That's hard to do if it's dark. Especially if it's dark as soon as you get home from work. I like it getting dark later in the evening.
I think those of us who live in climates where you can only go outside a few months of the year need it more than those who can enjoy outside activites any time of year.

Someone just tell the sun to rise at 6:00 am every day and set at 8:30 pm everyday, everywhere around the world.

It depends on how far west you are. Here in MN it's daylight until about 10pm and I love it! So do the farmers who need to see to tend to their crops. In Ohio, in summer, it's never daylight past 8:30-8:45 where I grew up. It was always dark by 9. So moving further west had its advantages!

In the heat of Summer you can't be outside until after dark any way.
After about 1 it's just too hot. You have to find a big shade tree and something cold to drink. If your lucky there is a stream you can wade in.

I actually think north and south is affected, too. I'm straight south of Michigan now, and we are not light as late as they are. I think northern cities stay light longer.

Yes. Because if you remember your science, the earth isn't straight up and down. It's tilted on its axis and the north is closer to the sun than the south. The south is in the shade, even though it's warmer.

Yep, days are longer in the summer, shorter in winter, in the north.
LOL, back to MM's point, we live just over a hundred miles from Mountain Time Zone, so yeah, Central Time Zone has a huge difference for sunset time compared to the eastern edge of the same time zone. Same amount of actual sun time, just different setting and rising times.

Exactly. How much daylight and when you get it depends a whole lot on where you are geographically. North, south, east, west. The sun hits different places at different times.
Because of this, I don't think you'll ever please everyone. No matter what you do, someone's not going to like it.

Someone just tell the sun to rise at 6:00 am every day and set at 8:30 pm everyday, everywhere around the world.
It depends on how far west you are. Here in MN it's daylight until about 10pm and I love it! So do the farmers who need to see to tend to their crops. In Ohio, in summer, it's never daylight past 8:30-8:45 where I grew up. It was always dark by 9. So moving further west had its advantages!
You lost me on this, MM.
I actually think north and south is affected, too. I'm straight south of Michigan now, and we are not light as late as they are. I think northern cities stay light longer.
Yes. Because if you remember your science, the earth isn't straight up and down. It's tilted on its axis and the north is closer to the sun than the south. The south is in the shade, even though it's warmer.
The position of the earth, in it's orbit, is also closer to the sun during winter, but the earth is tilted away from the sun. During our summer, when the northern hemisphere is tilted toward the sun, the earth is farther away from the sun. A bit of an oval orbit, since it's not perfectly circular.
