The staff at Kings Langley Secondary School have their blood pressure monitored as part of an investigation into work-related stress.
Host Hermione Cockburn is joined at the school by blood pressure expert Dr Nadia Wager. Nadia shows how she has been remotely monitoring teachers' blood pressure while they are teaching to discover how a stressful job can lead to heart problems.
Dr Mark Hamer helps analyse the biometric data that is being collected by a team of scientific experts at the school.
Meanwhile, two staff members at Kings Langley show how they respond to the pressures of teaching.
