As spring approaches, Italy prepares for the annual switch to daylight saving time, a practice that has been part of the nation's calendar since 1966. This year, the change will occur in the early hours of Sunday, March 30, 2025, when clocks will move forward one hour between 2 AM and 3 AM. For many, this means losing an hour of sleep, but it also signifies longer daylight hours as the country transitions into the brighter days of spring and summer.
According to Terna, the company managing Italy's national electricity transmission grid, the shift to daylight saving time is expected to yield significant economic and environmental benefits. Over the seven months that daylight saving time is in effect, Italy is projected to save approximately 100 million euros through reduced electricity consumption of about 330 million kWh. This reduction in energy use will also lead to a decrease of around 160,000 tons of carbon dioxide emissions, contributing positively to the environment.
The historical roots of daylight saving time trace back to the early 20th century, with its first implementation in Italy occurring during World War I. The practice was officially adopted in 1966 as a response to energy shortages. Since then, it has become a regular part of Italian life, aligning with the European Union's standard that mandates the change on the last Sunday of March.
However, the transition is not without its challenges. The shift can disrupt the body's internal clock, leading to various health impacts. People may experience fatigue, irritability, and difficulties with concentration as they adjust to the new schedule. Studies, including one conducted by the European Commission in 2015, indicate that changes in biorhythms can significantly affect health. Symptoms can include sleep disturbances, changes in appetite, and fluctuations in mood.
For many, the loss of an hour of sleep can be particularly jarring. Individuals who are naturally early risers or those with strict daily routines, such as children and the elderly, may find the transition especially challenging. Pets, too, can be affected by the shift in schedule, as they often rely on their owners' routines.
Experts suggest several strategies to ease the adjustment period. Gradually shifting bedtime earlier in the days leading up to the time change can help. Simple practices, such as reducing light exposure in the evening and maintaining a calming bedtime routine, can also facilitate a smoother transition.
Despite the temporary discomfort that may accompany the switch to daylight saving time, many people appreciate the longer evenings filled with natural light. This additional hour of daylight can enhance outdoor activities, improve mood, and even contribute to road safety due to better visibility during peak hours.
While daylight saving time is celebrated for its benefits, there is an ongoing debate about its necessity. Some argue that the health impacts and disruption to people's routines may outweigh the advantages. Discussions continue at the European level regarding the potential abolition of the time change altogether, but no definitive decisions have been made.
As Italy prepares for the transition, residents are reminded to set their clocks forward one hour before going to bed on Saturday night. Most digital devices, such as smartphones and computers, will automatically adjust, but it's essential for those with analog clocks to remember to make the change manually.
Daylight saving time will remain in effect until Sunday, October 26, 2025, when clocks will revert to standard time, bringing the familiar rhythm of the seasons back into sync. Until then, Italians can enjoy the benefits of longer days and the promise of warmer weather ahead.
