Host Hermione Cockburn is joined at Kings Langley Secondary School by stress expert Dr Angela Clow, who reveals the results of hormone testing on the teachers as part of an investigation into work-related stress.
Dr Clow explains that levels of cortisol, a strong indicator of stress, increase when teachers are at work compared to when they are relaxed.
A team of scientific experts continue to monitor teachers in the classroom. Dr Clow helps Hermione analyse the biometric data that is being collected.
Kings Langley is taking part in the experiment to monitor and evaluate the stress levels of the workforce and to help answer the question: how stressed is your school?
