Clocks Change This Weekend—Here's What You Need to Know!

This weekend, people across Ireland, along with many other countries, will turn their clocks back by one hour as daylight saving time (DST) ends. While this adjustment may seem routine, it significantly affects our health, productivity, and lifestyle. Understanding these factors can help us navigate the transition more smoothly.

The origins and purpose of daylight saving time

Daylight saving time has a long history, first proposed by New Zealand entomologist George Vernon Hudson in 1895 and popularised by British builder William Willett. The aim was to shift an hour of daylight from the morning to the evening, reducing reliance on artificial lighting and conserving energy. Widely adopted during World War I as a fuel-saving measure, DST has continued in various forms across many countries, including Ireland.

However, as society evolves, the original rationale for DST—optimising energy use—has come under scrutiny. Modern lifestyles, technological advancements, and flexible working patterns have diminished its relevance, leading to ongoing debates about its necessity.

Health impact of the clock change

While turning the clock back grants us an extra hour of sleep, even this small adjustment can disrupt our circadian rhythms. Our internal clocks, which regulate sleep-wake cycles, can be sensitive to changes in time. Though the autumn shift is generally less jarring than the spring transition, some individuals may still experience altered sleep patterns, mood swings, or reduced alertness.

Research has shown that the spring clock change can lead to an uptick in traffic accidents and heart issues, primarily due to the abrupt loss of sleep. Although the autumn transition tends to be easier, it's essential to be aware of how any shift in routine can affect our well-being.

Effects on productivity and daily Life

The change in time also influences our daily lives. While the extra hour of morning light can be beneficial, earlier sunsets mean shorter evenings, which can limit outdoor activities and reduce productivity after work or school. For those who depend on natural light for their work, such as farmers and builders, the shorter days can be challenging.

Additionally, commuting home in darkness can feel more draining, and the reduction in daylight may lead to a more sedentary lifestyle during winter months. Seasonal Affective Disorder (SAD), a type of depression linked to decreased daylight, can be exacerbated by the clock change, making it harder for some to cope with the longer nights.

The debate over daylight saving time

Calls to abolish DST are growing. Critics argue that the disruption to our natural rhythms outweighs any benefits, and in the European Union, discussions about ending the biannual clock change have gained traction.

Proponents of permanent daylight saving time argue for longer evenings to encourage outdoor activities, while standard time supporters emphasise brighter mornings' benefits for safety and overall well-being.

Preparing for the change

As we prepare for the clock change, consider how to make the transition smoother. Gradually adjusting your bedtime in the days leading up to the change can help your body adapt. Reducing screen time before bed and ensuring exposure to natural light in the mornings can also assist in regulating your sleep patterns.

For families with young children, slowly shifting bedtime routines can help minimise disruption during this transition.

As the clocks go back this weekend, it’s more than just an extra hour of sleep. Whether daylight saving time continues to be observed remains a topic of debate, but understanding its impact can help us better navigate the seasonal shift. Don’t forget to adjust your clocks, and enjoy that extra hour of rest!
