During the six-month DST period, the country is divided into five time zones.

Daylight saving time is observed from the first Sunday in October when the clocks turn forward and the clock ends on the first Sunday in April when the clocks turn back an hour.

Most smartphones and computers update the time automatically but other devices such as analog clocks, alarm clocks, cars and microwaves will need to update manually.

Some experts warn that shifting the time by an hour can affect sleep and circadian rhythms for longer than just an hour lost overnight.

Dr Sveta Postnova, University of Sydney School of Physics, said: ‘Experimental data indicate a cumulative effect of sleep loss lasting at least a week and sometimes longer. 7 news.

A recent survey by ResMed Sleep Health shows that one in four Australians actually don’t get enough sleep and nearly half of the adult population has trouble sleeping three or more nights a week.

“Spring ahead can actually represent major sleep health issues for some of us,” said Dr. Carmel Harrington of ResMed.

“We may get another hour of daylight, but our bodily clock is not very quick to adjust and we will find it more difficult to fall asleep before that hour and more difficult to wake up at that hour early.”

She recommends getting up and going to bed earlier on Saturday to help tune your body to the time difference and to make the bedroom bright to help wake up.

“It will reduce energy use, increase economic activity and provide most people with a better quality of life,” Dr. Preirao told the AAP last year.

Despite these benefits, some medical experts have called for the abolition of daylight saving time with concerns that shifting clocks forward could have a negative health impact.

Paul Zimet, a professor in Melbourne in Monash University’s department of diabetes, has raised concerns that the health risks associated with missing an hour of sleep going forward may be exacerbated by the Covid-19 pandemic.

“In terms of the scientific evidence, which we’d like to stick to right now, there are more heart attacks right after daylight saving time, more road accidents, and then there are workplace accidents, car crashes and their aftermath,” he told 3AW last year.

Daylight saving time was first introduced in some parts of the world during World War I under the idea that it would save fuel by using less electricity.

Research has shown that any effect of summer savings on energy consumption is not significant.

Experts say daylight saving time can disrupt sleep cycles for a week or more, with some calling for an end to the change to daylight saving time due to health concerns linked to the hours ahead.
