When we translate the clock ahead to daylight saving time, it is said by some researchers, in our bodies is a violation of rhythm and minor reduction of sleep, enough to cause a heart attack in some people.
"Every cell in the body has a molecular clock that allows cells and organs to predict the day's events," - says Martin Young, Ph.D., professor at the University of Alabama at Birmingham. "When there is a change of time, such as shift work, travel with the change of time zones or daylight saving time, these cells have to" reset "their internal synchronization mechanism.
Researchers at the Karolinska Institute in Stockholm used the clock for daylight saving time as a way to study the effect of small reductions in sleep.
The researchers found a slight increase in heart attacks during the week after the clocks moved forward. Wednesday, people taking heart medications, and have low levels of cholesterol and triglycerides in the blood, the risk was more pronounced.
No statistically significant changes in the frequency of heart attacks, after the autumn "return" arrows were noted.
"Our data suggest that even a modest reduction in sleep and impaired sleep-wake cycle may increase the risk of acute myocardial infarction in the population," - the authors write. "Identification of high-risk sub-groups can afford to implement prevention strategies to reduce the risk».
Yang also noted that the majority of heart attacks occur on Monday morning. As a precaution, before switching it offers hours to set up your clock on 20 minutes in advance at intervals of a few days just before daylight saving time.
