Turning clocks forward an hour for daylight saving time in the United States is followed by a spike in heart attacks on the Monday afterward, according to a study.
 
But when clocks fall back and people gain an hour of sleep, there is a drop in heart attacks on the Tuesday, said the research, presented at the American College of Cardiology conference.
 
The findings showed no change in the total number of heart attacks during the entire week following any clock change, indicating the spike seen on Monday is levelled out in the days that follow.
 
But knowing that a surge in patients can be expected in the emergency room could help doctors better prepare, said lead author Amneet Sandhu, cardiology fellow at the University of Colorado in Denver.
 
 
 
"It may be that we, as people, are very sensitive to the loss of even one hour's sleep," Dr Sandhu told reporters.
 
"It may mean that people who are already vulnerable to heart disease may be at greater risk right after sudden time changes."
 
The study was based on a database of hospitals in Michigan.
 
There was a 25 per cent jump in the number of heart attacks occurring the Monday after the spring time change - or a total of eight additional heart attacks - and a 21 per cent drop the Tuesday after the fall return to standard time.
 
 
Monday is traditionally the day when most heart attacks occur, previous research has found.
 
But by looking at hospital data over four consecutive years, researchers saw a consistent 34 per cent increase in heart attacks from one week to the next at the spring time change.
 
There were an average of 93 heart attacks the Monday before compared to 125 the week after the start of daylight saving time across those four years.
 
Daylight saving time in the US - implemented to save energy during World War I - is controversial and some believe it is not needed anymore.
 
Dr Sandhu said future research should compare the Michigan findings to heart attack trends in Hawaii and Arizona, which do not have daylight saving time.

Don't mess with biological clocks. They evolved without DST and don't like its imposition.

DST creates more trouble that offset the benefit that whatever 'saving' it suppose to do.

Killing people from heart attacks and lack of sleep apparently.

Daylights waste of time, should just be always on or always off.  It serves no real purpose other than lighter out later in the time that it is on, thus more people shop later.  The energy savings is not really a valid argument in this day and age.

Why do old people have more sex the day following the start of daylight saving time?

Murrica!

 

If I had to guess, I'd say it was because they spent the previous day gorging on pancakes, bacon and other high calorie foods and then flipping channels from the couch all day long.

FYI - DST is not just a US practice, and its purpose varies, so your "Murica!" comment begs for some some education,

Oh I know DST is not US specific, we observe it here too, but high obesity rate among children and heart attacks on Monday after losing an hour of sleep just might be. ;)

How is saving energy no longer important?

Aren`t we all moving towards greener lives?

Maybe I dreamt all that stuff about the environment and ozone layer, not as if the polar ice caps are melting or that....

Are we really that fragile? One hour sleep (more or less) can be a matter of life and death? I never sleep the same amount of hours.

Move the clock an hour forward when you wake up, if your body is not capable of handling one hour less sleep.

Yes, our internal rythms can be that "fragile." Ever travel and get desynchronosis (jet lag)? It's a similar stressor that over time can cause an increased risk of cancer, infertility, and heart disease. So says the NIH. Now add any cardiac risk facorrs you may have and....

The bottom line is that regular sleep patterns can be very important. Ignore at your own risk.

It's probably the stress of having to ask everyone whether the clocks go forwards or backwards.

Exactly. Totally ridiculous blaming that one hour difference for all the heart attacks. Do people normally sleep for exactly the same amount of hours every night? Do they go to bed and wake up at exactly the same time every day? I think not.

Just so you know, the US does not have the highest obesity rate in the world. That would be Mexico.

It depends on each person. Some people are VERY fragile and some doesnt matter if they sleep 1 or 8 hours.

Also, note that most people are drugged during their day various times (caffine), so that affects their sleep as well, while others are drug free.

The trouble is that the majority of people DON'T get enough sleep per night - "I'm fine with six and half hours of sleep [after a coffee]", but little do they know about the risks their taking. I personally don't drink or need coffee.

 

I'm in with the abolish daylight saving group.

Bit insane to imply that an increased rate of attacks is a direct correlation of daylights saving, but im very much of the opinion, that sleep is very important and regular patterns, even with slight fluctuation for the individual is very, very important.

There`s an absolute plethora of sleep related mental health issue`s out there, and that`s before we even get into the physical ones.

Best example I can give is the "fight or flight" mechanism. This can be triggered in such a way by sleep deprivation or pattern deviation that you can have some pretty serious panic attacks. These also lead to a form of shock in which the brain wont shut down despite the body`s utter need for rest. (Starting to think maybe there`s a tiny correlation, but not as big as suggested.)

I know this as I onced stayed up for around 5 days in my younger party days, needless to say the feeling you WILL die if you go to sleep is horrific and I ended up being taken to A&E to be sedated.

Totally agree with you.

 

I can actually backup what you said about the fight or flight feelings. I suddenly started suffering from severe agoraphobia and panic attacks from the age of 21 and i can vouch for the fact it's very much like the feelings you get when you lack sleep to a dangerous level.

How does DST save energy? For a couple weeks, we're back to having to turn the lights on when we first get up, and turn them on a little later in the evening  . . . Yay?

 

I hate the fact that it's finally light out when I get up for work, and then after DST kicks in, it's suddenly dark again. Very depressing.

 

I don't know that it ever actually saved any energy, and it certainly doesn't these days.

in some area/homes they even use light sensor to automaticaly turn on/off lamps, based on day brightness rating, DSTrick needed at that?
