Cryotherapy, sleep apps and binaural beats, are just some or the more than 20 hacks Lisa Leong uses to perform her best at work. Are they useful or a complete waste of time and or money? We recruited three scientists to run the research filter over these hacks. DR SHONA HALSON is a leading exercise recovery scientist who has been part of three Olympic campaigns, she sorts the fact from fiction when it comes to cryotherapy. DR SIOBHAN BANKS, neuroscientist and sleep researcher from the University of South Australia, reviews wearable sleep apps and developmental neuroscientist from Monash University DR HANNAH KIRK debunks binaural beats for increasing focus. Lisa's fellow biohackers for high performance at work include DIANNE MCGRATH (Mars One astronaut candidate) and entrepreneur and non-executive director CATHERINE ROBSON.
