Introduction
Daylight saving time (DST) is a practice adopted by various countries around the world, where time is adjusted by an hour during specific times of the year. The purpose of DST is to extend daylight hours, saving energy and allowing people to work and carry out activities for more extended periods. The practice has both its proponents and detractors, with some people advocating more widespread use of DST, while others seek to end the practice altogether. In this article, we will explore which countries participate in DST and its global impact.
The Global Impact of Daylight Saving: Which Countries Do It?
Currently, approximately seventy countries worldwide practice DST. Countries in Europe, North America, and parts of Australia favor DST. In Europe alone, 44 countries adjust their clocks to Daylight Saving Time, while North America is split between those who participate and those who do not.
There are several reasons why countries adopt DST. One of the main advantages is that it extends daylight hours, enabling people to carry out activities for more extended periods. This is particularly important for countries with long winters and fewer hours of sunlight. The practice also saves energy by reducing the need for artificial light. For instance, studies have shown that the United Kingdom saved approximately 490,000 MWh of electricity in 2019 from DST.
However, there are also downsides to DST. One of the most significant disadvantages is the disruption to circadian rhythms, which can lead to sleep disturbances, mood changes, and even an increased risk of heart attacks. The practice can also have economic impacts, such as disrupting travel schedules and business activities. Also, some people argue that extending daylight hours during the summer negatively impacts certain industries such as farming.
Spring forward, fall back: A Guide to Daylight Saving Time Around the World
DST means advancing clocks forward by one hour during early springs and changing them back one hour during autumn fall. While the day it starts and ends is not universal, most countries begin it on the last weekend in March and end it on the last weekend in October.
While countries like the United States start DST on the second Sunday in March, Germany initiates the practice a month later, on the last Sunday in March. Australia starts DST, more specifically Eastern Australia, on the first Sunday of October and ends it on the first Sunday in April.
The practice of DST dates back to the 20th century in Europe when Germany began implementing it to save coal during World War I. Since then, several other countries have adopted the practice, although there have been periods when it has been abolished.
The Pros and Cons of Daylight Saving: Which Countries Got It Right?
While DST has its advantages, there are also some downsides to the practice. One of the notable advantages is that it saves energy, reduces road accidents, and encourages outdoor activities. On the other hand, one of the cons is that it could lead to adverse health effects, such as sleep deprivation and increased stress.
Some countries have tried to find a balance between the pros and cons of DST. For instance, in Russia, they extended the daylight saving period from six to seven months to allow businesses and retailers to adjust to the changes and reduce energy expenses. In contrast, Iceland, Belarus, and Armenia have abolished the practice altogether based on studies that show its disadvantages outweigh the benefits.
Killing Time: Which Countries are Considering Doing Away with Daylight Saving?
While many countries continue to participate in DST, some, including the European Union, are considering ending the practice. Some reasons why countries are debating whether to stop daylight saving altogether is lack of information and concerns over adverse health implications. Spain, for instance, has proposed abolishing DST since it does not see any advantages to extending daylight hours.
How Daylight Saving Affects Your Health: An International Look
Research conducted on the effects of DST on health is not conclusive. In many instances, the effects on individuals depend on circadian rhythms and genetics. Studies have shown that cardiovascular disease and incidences of myocardial infarction increased by around six percent in the first week after DST takes effect. In terms of mental health, some studies suggest that the end of DST is associated with a decrease in depression symptoms.
The Science Behind Daylight Saving: The Countries Leading the Way
Several countries all over the world have been conducting research on the effects of DST. Among these, Finland stands out for its extensive research into the health impacts of DST. Meanwhile, Chile and Brazil have embraced a rather innovative approach to DST, where the adjustment is dependent on latitude and geographical position.

DST affects different countries in unique ways based on their geography and climate. Some countries in the Southern Hemisphere do not follow the practice of DST at all, explaining that during summer, the days are already long and hot. In contrast, countries located in the higher latitudes experience fewer daylight hours during winter and have different needs when it comes to DST.
Conclusion
DST is widely adopted for its benefits, such as increased productivity and energy conservation, but negative health implications and economic effects are of increasing concern. Some countries have already done away with the practice, while others are debating the merits and disadvantages of DST. Despite the debate, the pragmatic decision in many countries seems to be sticking to the status quo. Given the complexity of the issue and unique impacts of DST, the future of DST will continue to be a subject of discussion in countries worldwide.
