The History of Daylight Saving Time (and How It Still Impacts Us Today)

​Learn the history, surprising facts, and tips to adjust smoothly this fall.

☀️ A Tradition That Started with Energy Efficiency
Daylight Saving Time (DST) was first introduced during World War I as a way to conserve fuel by maximizing daylight hours. The idea was simple: if people had more daylight in the evening, they’d use less artificial light — saving energy for the war effort.

The U.S. officially adopted DST in 1918, repealed it after the war, and brought it back again during World War II for the same reason. In 1966, the Uniform Time Act standardized the start and end dates nationwide, though some states like Arizona and Hawaii still choose not to observe it.

🕯️ Does Daylight Saving Time Really Save Energy?
While DST was once effective for reducing electricity use, modern studies show the savings are now minimal. With air conditioning, electronics, and year-round activity, our energy habits have shifted.

A U.S. Department of Energy report found that DST reduces total energy use by only 0.5% per day, but the benefits today are more about lifestyle and safety than power savings.

🚗 The Safety Connection: Why It Still Matters
Interestingly, adjusting the clock impacts more than just our schedules — it can also affect accident and crime rates.

• Evening daylight means fewer car crashes and pedestrian accidents after work hours.
• Extra light can deter certain types of crimes during early evening hours.
  However, studies also show a short-term increase in accidents the week following the time change, as people adjust to the new schedule.

😴 Health and Sleep: Adjusting to the Change
The switch may seem small, but losing or gaining an hour can temporarily disrupt your body’s circadian rhythm.

To adjust smoothly:

• Start shifting your bedtime by 15 minutes a few days before the change.
• Get morning sunlight exposure to reset your internal clock.
• Keep your evening routine calm and screen-free for better rest.
