Daylight saving time (DST) has been reported to have been used for the first time in 1908 in Thunder Bay, Canada.

It was created to save energy and to be more productive.

Daylight saving time is when clocks in parts of countries like Canada and the United States of America (U.S.A.) are set an hour back.

Setting the time back is done to correlate with more sunlight being in the morning than later in the day, like during the spring and summer seasons.

Experts like Rebecca Robbins, Ph.D., a scientist at Brigham and Women's Hospital and an assistant professor at Harvard Medical School, have stated on ABC News that having standard time is safer for children as they will have more light to get to school.

Also, Rebecca Robbins, PhD, stated that sunlight may help to stop melatonin, which is associated with sleep, and enhance the circadian rhythm, which is linked to being awake. This may contribute to a better start to the day.

Melatonin is a hormone produced by the brain as it reacts to darkness.

Circadian rhythms are the changes living things undergo during a 24-hour cycle.

Inna Rabinovich-Nikitin, a post-doctoral fellow at St. Boniface Research Center, has realized from research that having a healthy circadian rhythm helps to prevent diseases and may impact the outcome after a heart attack.

There is no consistent evidence that shows that daylight saving time saves energy or improves productivity.

According to the Chmura Economics and Analytics study titled ‘ Estimating the Economic Loss of Daylight Saving Time for U.S. Metropolitan Statistical Areas,’ the total cost of lost hours was over $400 million.
