Daylight Saving Time (DST) is a widely practiced global ritual in which people adjust their clocks to strategically utilize daylight. With seasonal changes, DST becomes more necessary as it aims to extend daylight during warmer seasons by an extra hour during late afternoons and evenings. Over 70 countries actively participate in this practice, adhering to varied schedules. However, countries closer to the Equator, where there are minimal fluctuations in daylight hours between seasons, do not observe DST. This includes India, which doesn’t implement DST.
Origin of Daylight Saving Time
The initiative of DST was first implemented on July 1, 1908 in Port Arthur, Ontario, by a group of Canadians. They set the precedent by turning their clocks forward by an hour. Following their lead, other Canadian locations soon adopted this practice. The concept of DST garnered global attention when Germany and Austria introduced it on April 30, 1916. Their rationale behind this adoption was to curtail the use of artificial lighting, thereby saving fuel amidst World War I.
Does Daylight Saving Time Contribute to Energy Conservation?
When DST was initially introduced, added hours of daylight translated into lowered reliance on artificial light. However, with the technological advancements in contemporary society, our dependence on energy-consuming appliances has escalated significantly. As such, the energy saved from reduced usage of artificial light during DST has become rather insignificant. Moreover, practicing DST is not without drawbacks. A notable downside includes the disruption of the human body clock or circadian rhythm.

Understanding the Circadian Rhythm
The circadian rhythm plays a crucial role in regulating our sleep patterns, eating habits, and other vital physiological processes. It is essentially a 24-hour cycle that interacts with environmental cues such as sunlight and temperature to dictate our energy levels throughout the day. Disruptions to this cycle, as can be caused by DST, can significantly alter these rhythms, potentially leading to feelings of fatigue or restlessness.
This biological clock doesn’t go unnoticed in the scientific world. In fact, Jeffrey C. Hall, Michael Rosbash, and Michael W. Young received the Nobel Prize in Physiology or Medicine in 2017 for their extensive research into the molecular mechanisms controlling these rhythms.
