PSA: Daylight Savings Will Begin Tonight

After the clocks wind forward on Sunday for daylight saving people need to be aware of their drowsiness levels to prevent accidents, sleep experts say.

Research shows a rise in accidents during the 24 hours immediately following the time difference, highlighting the importance of getting enough rest.

"Try to get a bit more sleep in that 24-hour period when the clocks change, be mindful of alcohol and not partying too much," Dr Moira Junge from the Sleep Health Foundation told AAP.

The morning after daylight saving occurs Dr Junge encourages people to get outside or access to daylight as soon as possible to suppress melatonin levels in the body, the sleep regulating hormone.

But just like flying interstate into a new time zone, Dr Junge said, the body clock will adjust fairly quickly.

"Don't over-think it too much; while there is a shift in our body clock, it's only for a short period of time," she told AAP.

"We adapt within a matter of days."

Clocks will be turned forward one hour on Sunday 7 October from 2am in NSW, Victoria, the ACT, South Australia and Tasmania.

Daylight savings always falls on the first Sunday of October.
