Recently, a study has been published linking daylight savings to heart problems, more specifically heart attacks. The most recent data suggest that after the world has set their clock one hour forward this year the rate of heart attacks dropped with 5%. Scientists believe that this is because people can now sleep more and considering that sleep deprivation is closely related to people suffering from heart disease it all seems pretty logical.

This is not only good news as Swedish researchers pointed out that when we need to adjust our clocks in spring the opposite effect takes place.

As it turns out it is all related to sleep and how people perceive the notion of time linking it with the time to rest. In spring there is the feeling that one hour has been stolen from our sleeping time and the latest study shows that this directly affects people with cardiac issues.

Scientists have shown that, generally, sleep deprivation is bad for the heart as there is a tendency in the body for high blood pressure and high heart rate which can lead for dangerous clots to form.

The study focused on the heart attacks that occurred in the following seven days after clocks were changed from 1987 to 2006. The results are crystal clear: daylight savings, moving our clocks forward or backwards definitely has an effect on the rate of heart attack hospitalization. In spring heart attacks have the tendency to occur more often as when we change our clocks in October heart attack rates go down.
