It’s time to set the clocks again as daylight saving time begins on Sunday | Community alert


Texas and most of the rest of the United States “spring” into this annual rite of spring, adjusting clocks – and smoke detectors – for daylight saving time.

At 2 a.m. Sunday, 48 states will move the clocks forward one hour — the same way they have done most springs and autumns for the past 104 years. It was first enacted in 1918 to add another light hour to produce armaments during World War I, then during the Great Depression and again during World War II, when it was commonly referred to as light time. war.

The US government says the history of DST is tied to energy conservation, which, given current world events, couldn’t be more timely. Put simply, daylight saving time means that in the summer there’s an hour’s delay to turn the lights on in the morning and off in the evening – and excuses for putting off until tomorrow what should have been done. yesterday.

Since 2007, daylight saving time begins on the second Sunday in March and ends on the first Sunday in November. Critics of DST claim that changing clocks twice a year disrupts sleep schedules, increases car accidents as well as the risk of heart attacks, seasonal depression and other health problems.

In 2008, the U.S. Department of Energy said that sticking to a single period all year could save the entire country 0.5% in electricity consumption per day, or enough to supply 100,000 households for one year. Another report indicates that the energy required to change the clock leads to a 25% increase in heart attacks in the days following the change.

And a 2009 study by the American Psychological Association indicated the adverse effects of daylight saving time in the workplace. He said that immediately before the start and just after the end of DST, employees slept 40 minutes less and had 5.7% fewer workplace injuries. But it led to 67.6% less work time due to injuries outside of the workplace (the study used data from the mining industry between 1983 and 2006).

For years, the American Academy of Sleep Medicine has advocated a permanent switch to standard time, saying “there is ample evidence of the short-term negative consequences of seasonal time changes.” The AASM recommends these tips for managing the time change:

• Sleep at least seven hours (for adults) or eight hours (for teenagers) a night before and after the clock change.

• Gradually adjust your sleep and wake times. Shift your bedtime 15 to 20 minutes earlier each night for a few nights before the clock change.

• Adjust other daily routines, such as meal times, to match your new schedule before the time change.

• Advance your clocks one hour on Saturday evening March 12 and go to bed at the usual time.

• Go outside to enjoy the sun on Sunday morning. The bright light will help set your biological clock, which regulates the rhythm of sleep and alertness.

• Get enough sleep on Sunday night to ensure you are rested and ready for the week ahead.

Arizona’s independence from daylight saving time can cause a lot of confusion for residents and visitors. This means that the state is in the same time zone as Denver from November through March, but then falls behind Denver time in Los Angeles from March through November. This confused Indiana, the most recent state to begin observing daylight saving time in 2006.

The most important aspect of Daylight Savings Time — aside from losing that hour of sleep — is that it’s a reminder to change the batteries in household smoke detectors. Most smoke detector batteries last up to 10 years, as most are now hardwired with backup batteries in the event of a power outage. But don’t forget to press the test buttons to make sure.

NBFD is still doing detector checks for residents, especially seniors, who call the department at 830-221-4200. In the meantime, know that sleep-deprived folks can rejoice when standard time returns to 2 a.m. on Sunday, November 6.
