Digital diet

● Have a non-tech lunch hour. Turn off your phone, put it in a drawer and enjoy your lunch without it.

● Schedule set times to look at social media, so it doesn’t become your default “brain snack” whenever you’re not doing something else.

● Batch your emails and only tackle them at certain times of day. “This is a calm inbox,” reads Brewer’s email postscript. “You will generally get a reply within 24 hours on business days.” ● Try phone-fasting. In his latest book, The Stress Solution, Dr Rangan Chatterjee recommends a 4:1 approach — putting your device in flight mode for one hour of every four that you are awake.
