Daylight Saving Time ends and watches will fall back an hour this weekend, giving Americans the feeling of an extra hour in the morning, which could negatively affect their health.

"Since Daylight Saving Time has been established, there has been a controversy over whether or not it achieves its goals, and if so, at what cost," said Timothy Morgenthaler, co-director of Clinic Mayo at the Medical Clinic Center . E-MAIL.

Morgenthaler looked at about 100 medical papers on how changing time could affect health.

Sleep

Acquiring or losing one hour will likely affect sleep, often for about five to seven days, Morgenthaler said. The most notable changes are those who normally do not have enough sleep. People who are deprived of sleep may struggle with memory, learning, social interactions and general cognitive performance.

"People have more changes in the way they feel sleepy feel or how they affect the quality of their sleep when we go up from when we fall back," said Morgenthaler.

Heart attack or stroke

According to a study conducted by the University of Colorado in 2014, when Americans lose one hour sleep in the spring, the risk of heart attack increases by 25%. When the clock returns sleep time, the risk of heart attack decreases by 21%. (The limited study looked at admissions to the Michigan hospital for a period of four years.)

A preliminary study presented at the 2016 American Academy of Neurology conference suggests that the clock in front or behind an hour could increase the risk of stroke. This is because the disruption of an individual's body clock may increase the risk of ischemic stroke, the most common type of stroke, according to researchers. Data showed that the risk of ischemic stroke was 8% higher two days after one year of time savings.

These studies are two of the many for these negative health effects, and they do not always paint the whole picture, said Morgenthaler.

"From several publications between 2010 and 2014, three studies have shown that DST increases the risk of acute myocardial infarction (AMI), but two others have shown that the timing (but not the incidence) of strokes and AMIs can influenced by DST "Morgenthaler emphasizes.

It crashes

Many have also studied the impact of changing time on vehicle crashes and deaths. Larger studies correcting volume and driving activity as well as time of day "do not show significant impact" on daylight saving time changes, Morgenthaler said. However, it warns to stay informed when driving or walking near a road, especially early in the morning or late at night after the change.
