Coles is planning on making shopping easier for people with autism by introducing ‘Quiet Hour’ at 68 supermarkets around the country from Tuesday.

For one hour each week, the stores will switch off the radio, dim the lighting by 50 per cent and reduce register volume in a move to help shoppers who struggle with heightened sensory environments.

The initiative saw an overwhelmingly positive response from Victorian shoppers during trials earlier in 2017.

No trolley collections will take place during Quiet Hour, while announcements will only be made in emergencies.

The 'Quiet Hour' will take place between 10.30am and 11.30am every Tuesday.
