A Moment of Respite: Daylight Saving Time Concludes, Providing Additional Rest and Unexpected Changes
Daylight Saving Time (DST) was initially introduced to save energy by making better use of extended daylight hours during summer.

Some studies suggest that DST leads to a reduction in energy consumption, with a 0.5% decrease in daily energy use in American homes.

The overall energy savings due to DST in the United States amount to nearly 1.3 Tera Watt-hours (TWh) per year.
The impact of DST on energy consumption appears to vary based on factors such as geographic location, local climate, and changes in people's behavior.
Despite the additional rest, experts warn that bi-annual clock changes can have negative health effects.
Research indicates that these time shifts disrupt sleep routines and can lead to health consequences, as per a Harvard Health report published earlier this year
The report highlights that losing an hour of sleep in the spring is particularly disruptive to the body's circadian rhythm, which regulates sleep, mood, appetite, and other vital functions
Researchers in Indiana theorized that DST reduces household lighting demand but increases cooling needs in summer evenings and heating requirements in early spring and late fall mornings.
