Daylight Saving Time is not just about setting your clock one hour ahead before going to bed on Saturday night.

Safety officials are using this moment of the year to remind us another important task that may be related to “spring forward.” So, don’t forget to check batteries in your smoke detectors. It may save your life in case of an emergency.

Firefighters say that alarms and detectors save lives if they work properly. They advise people to replace their smoke alarm every ten years and the carbon monoxide detector every five to seven years.

Most of the US moved to Daylight Saving Time at 2 a.m. Sunday, except for Arizona, Puerto Rico, Hawaii, the U.S. Virgin Islands and American Samoa.

More than 1.5 billion people turn their clocks forward in the spring and backward in the fall. Studies have noted that the lack of sleep associated with the springtime shift may affect people, adding an increased risk for several heart attack risk factors including high blood pressure, inflammation and obesity.

According to a study conducted last year by researchers at the Karolinska Institute in Stockholm, in the week after “spring forward,” there was a 5 percent increase in heart attacks, with a 6 percent bump on Monday and Wednesday and a 10 percent increase on Tuesday. The effect was more pronounced in women. The phenomenon may be attributable to the lack of sleep and the adverse effects of sleep deprivation on cardiovascular health.
