Listen to the story

Twice a year, clocks change in many countries. This includes the move to solar time, also called 'winter time'.

Experts compare this change to a jet lag, which usually happens after long flights. Even though the clock only moves one hour, it can confuse the body's internal clock.

This internal clock controls sleep, energy, and mood. A small change can still cause tiredness or trouble sleeping for a few days.

In Italy, this topic is also political. A member of the Lega party, Barabotti, spoke about the issue. The Camera, Italy's lower house of parliament, voted. All members agreed to end the system of changing clocks twice a year.

This kind of vote is called unanimous, meaning everyone agreed. However, it is not yet clear when this change will fully happen.

People are also asking simple questions. When does solar time start? Do clocks move forward or back? These questions come up every year before the change.

Health experts suggest preparing a few days before the change. Going to bed a little earlier or later can help the body adjust more easily.
