This morning (March 30), the clocks went forward 60 minutes. The purpose of this change is to push the sunset later in the day and the sunrise later in the morning. This shift will probably cause you some sleep problems for the first few weeks. However, although the nights will be shorter and you will sleep less, experiencing longer days will change your mood.

Why do we change the clocks every year?  The concept began in the United States to save energy during World War I and became a global standard in the 1960s. The idea is to push daylight hours further into the evening. So if the sun sets at 8:00 PM instead of 7:00 PM, we'll spend less time with the lights on at home, saving electricity.

Also, people will not sleep during the morning sunlight hours, as they are also pushed back an hour. This means that the sunlight hours will be productive and used effectively.

Does it really save energy? In fact, studies have found that the impact is minimal, if not nonexistent.

Is the clock change dangerous?

A little. When the clocks go forward 60 minutes, many of us lose an hour of sleep. Our biological clocks are a little out of whack. Humans are fragile beings, and the smallest change has an impact.

When it comes to the time change, many people experience it mentally and feel out of sync with the world.

Previous studies have noted an increase in car accidents the morning after the clock change, as well as workplace injuries. Others experience changes in their sense of humor and state of mind; sleep problems that easily lead to boredom, fatigue, irritability, or in some cases even depression; difficulty concentrating or headaches.

These symptoms, although felt by some people, disappear quickly. It is enough to get used to the new clock cycle and the lost hour of sleep.
