Kate Quilton and Dr Javid Abdelmoneim continue their health check of the UK, enlisting 10 stressed-out volunteers, ranging from a firefighter and a paramedic to a chef, to find out if simple lifestyle changes can alleviate stress. Is it as simple as cutting back alcohol and caffeine, while taking up hobbies and practising mindfulness meditation? Kate also visits Lego, a company leading the way on employee wellbeing, Javid shows how spending time in green spaces can reduce stress levels, and there's a look at pioneering treatment for people with phobias.
