I would bring attention to this article available online,
It says some of the same things I have brought up before, but it is a
fact that is growing in awareness and confirmation, rather than going
away for lack of evidence. It will be at some time that policies will
have to reflect knowledge of this.
Is Daylight Saving Time Bad for Your Health?
The yearly change is sure to cause more than a few missed brunch
dates, and perhaps some confusion over why the alarm is going off an
But the hour shift in sleep schedule could also have more serious
effects on some people's health, according to experts on circadian
rhythms, particularly in people with certain pre-existing health
Dr. Xiaoyong Yang, an assistant professor of comparative medicine and
cellular and molecular physiology at Yale University, says "for some
groups of people — people who have depression or a heart problem —
there's some research that suggests that [they] have a higher risk of
suicide and heart attack."
An Australian study study published in 2008 in Sleep and Biological
Rhythms 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.
Another 2008 study, published by Swedish researchers in the New
England Journal of Medicine, found that the number of serious heart
attacks jumps 6% to 10% on the first three workdays after DST begins.
In other words, people who are already vulnerable to certain health
problems may experience more severe effects of their body-clock
disruption. Why that's so is still unclear, but Yang theorizes that
shifts in biologic rhythms could trigger harmful inflammatory or
metabolic changes at the cellular level, which these individuals may
be more susceptible to.
Problems to health that this article mentions can also have relation
to deprived sleep, that many people are affected by. I promote
getting adequate sleep, too.
