What is Daylight Savings?

Discover the history and effects of Daylight Savings, how it impacts our lives, and why we have it. Learn about the benefits and drawbacks of DST.


Daylight Saving Time (DST) is the practice of setting the clocks forward by one hour during the warmer months to make better use of daylight. Here’s a closer look at what DST is and how it impacts our lives.

History of Daylight Savings

The idea of DST was first proposed by Benjamin Franklin in 1784 as a way to save candles by making better use of daylight. It was later implemented during World War I as a way to conserve energy. Today, many countries around the world observe DST, although not all do so.

Why Do We Have Daylight Savings?

The main reason for DST is to make better use of daylight and save energy. By moving the clocks forward in the spring, people can enjoy more daylight in the evenings, which reduces the need for artificial lighting and saves energy. It also has other benefits such as reducing traffic accidents and promoting outdoor activities.

How Does Daylight Savings Work?

Typically, DST begins in the spring when clocks are set forward by one hour and ends in the fall when clocks are set back by one hour. This shift in time can disrupt our internal body clock, leading to feelings of grogginess and decreased productivity. However, it also means longer days and more time to enjoy outdoor activities.

Effects of Daylight Savings

While DST has some benefits, it also has its drawbacks. Studies have shown that the time shift can disrupt our sleep patterns, leading to an increase in accidents and health issues. It can also affect productivity and mood, as our bodies struggle to adjust to the new time.

Case Studies

  • In a study conducted by the University of Colorado Boulder, researchers found that the risk of heart attack increased by 25% on the Monday following the start of DST.
  • In another study by the University of Michigan, researchers found that workplace injuries increased by 5.7% in the week following the spring time change.


While DST has its benefits, it also has its drawbacks. It’s important to be aware of how the time shift affects our bodies and to take steps to minimize its impact. Whether you love it or hate it, Daylight Saving Time is here to stay.
