The featherlight saving time ended on Sunday. Why are we changing our clocks? And how does this affect our bodies?

When summer disappears in autumn, most Australian states and territories He will put off his clocks for an hour when the featherlight saving time and standard time resumes.

ABOUT one third The world also adapts their seasonal clocks, walking forward in spring and back in autumn (remember: spring forward; fall).

In the spring, losing the time of sleep can make us feel tired, naned and non -asynchronous, which makes it arduous to shake this long -term drowsiness in the following days.

Although the additional sleep hour in autumn may sound great, it is also not completely positive, because it moves from the time you gain or lose an hour – it can disturb our biological clock.

This is why Sleep experts and scientists who examine the body clock (Chronobiologists) They often oppose the changes of the biannic clock. They claim that we should eliminate featherlight saving time and stick to the standard time throughout the year.

So why do we first of all save daylight? And why is it controversial?

What time for featherlight?

Airy saving time was first introduced during World War I as a war means Keep your fuel.

However, up-to-date studies show that the time of saving featherlight is not significantly reduce General energy consumption. Maybe increase IT: while Australians Use less power We utilize more for air conditioning for lighting when saving daylight in warm weather.

Nowadays, saving daylight is discussed mainly due to the potential economic and social benefits, such as extended evening daylight for recreation, purchases and movement of movement, as well as for its health consequences.

What happens in our body?

People have a long -lasting, evolutionary biological or circulated clock.

Our biological clock regulates our dream and many other body functions, including when to eat and when we can achieve optimal physical and cognitive efficiency.

For everything to work smoothly, the biological clock depends on the natural daylight. The exhibition at the right time is particularly crucial for sleep. Morning sunlight helps you wake you up, and the evening featherlight signals your body so as not to fall asleep, which means that you stick later and get up later.

When we adapt time for our clocks by an hour, we change our social schedules, such as work or school times and social activities, as well as the time of featherlight exposure. When we switch our clocks to standard time, most people experience sunrise and sunset earlier in relation to their biological clock.

And vice versa, in daylight the morning featherlight is delayed, so later we meet sunlight in relation to our internal clock. This “Extremely circular“It can throw our biological clock from synchronization, adversely affecting body functions.

This is particularly problematic for people who already experience persistent non -coffee -free.Social jetlag), such as shift employees and those who prefer to remain overdue in the evening and wake up later in the morning (night owls).

Like “Spring ahead” can affect your health

Most research on changes in biian clocks historically focused on the spring switch, the transition from the standard saving of time to daylight.

Spring switch may cause lack of sleep within a week after the change of time and is associated with an boost of 5.7% Working injuries.

It is also associated with a higher risk cardiovascular and mental health problems, in research reporting an boost of 4-29% heart attack and an boost by 6% Mental health crises and improper use. They are attributed to piercing disturbances in a dream and a body clock.

Airy saving time is also related Long -term health consequencesEven after a few months.

At the standard time, the mornings are featherlight and the evenings are murky. But over time saving sunlight appears later, so you can stay later and you still have to wake up at the same time because of social duties.

When this pattern persists, it can cause long -term circular reference. This “social jetlag” was associated with worse cognitive performance AND Sanity.

How “fall” can affect your health

The autumn transition from daily time to save time to standard time is often seen as beneficial due to an additional hour of sleep.

However, some studies show Autumn passage Since the day of saving time back to standard time, it can disturb your well -being. It is connected with Increased anxiety At night, which violates sleep.

Has also been associated with growth Depressive episodes In Denmark, up to ten weeks after switching to standard time. This may result from a sudden beginning of earlier sunset, which signals the beginning of a long tiny period.

Where does it leave the debate?

. European Union AND United States They are on the path of lifting double -sided clock changes.

The EU proposal regarding the end of the two -seized clock changes was fundamentally approved and is waiting for the final agreement by all Member States.

The US Senate adopted the SUNSHINE Act, which now requires additional consent to become a law.

From the perinive health perspective, a constant standard time Align better with our biological clocks than permanently saving daylight.

But people do not have to sacrifice their lifestyle preferences to live in harmony with their biological clocks. The time of saving daylight does not provide more sunlight, it only changes the time.

Such straightforward lifestyle adaptations such as Flexible working hoursIt can allow people to start working earlier in the summer months and enjoy longer evenings, even without changing the clock twice a year.
