Daylight Saving Time Ends This Weekend

MINNEAPOLIS (WCCO/CBS News) -- This weekend, everyone is going to get the opportunity to take an extra hour of sleep. As the saying goes, "fall back, spring forward."

Daylight saving time ends at 2 a.m. this Sunday, so don't forget to turn those clocks back.

The City of Minneapolis said that daylight saving time is also the perfect moment to change your batteries in your smoke alarms and carbon monoxide detectors.

Officials reminded that it is Minnesota law to have at least one smoke alarm per house level.

Meanwhile, British researchers report they believe children's health would improve if we didn't "lose" that extra hour of daylight.

Researchers at the London School of Hygiene and Tropical Medicine studied whether increased daylight hours would increase kids activity levels. They looked at 23,000 children ages 5 to 16 from nine countries, including the U.S.

The kids in the study wore an electronic device around their waist to measure their body movement. Scientists found when it gets dark early, children are less active.

Researchers said the extra daylight that would come from not setting clocks back could mean 2 more minutes of running around each day. That may not sound like a lot, but researchers say children only get about a half an hour of vigorous activity a day, so even a little bit would help.
