With the threat of Covid hanging over the New Zealand summer, clinical psychologist Dr Sarb Johal's new book looks at how to keep mentally well during a crisis.
His new book is Steady: Keeping Calm in a World Gone Viral and it covers how stress and anxiety created by the pandemic's uncertainty can be overcome.
He joins Kathryn to talk about why humans are bad at dealing with threats - and especially extended ones - and what New Zealanders should be doing to minimise the Covid risk.
