It's summer and many people are planning a stress-relieving trip, while for many parents the school holidays are themselves a stressful time. But are we close to having a way for people to measure their own stress levels, and is this a good idea?
Everyone knows someone who is stressed out, whether it's over job worries, money concerns or personal problems.
Stress is notoriously difficult to define but measuring it could soon become official practice. The Office for National Statistics has been asked by Prime Minister David Cameron to assess the well-being of the population and has published details of a survey into what people think wellbeing embraces. It includes relationships with friends and family, job satisfaction, health and the state of the environment.
But aside from public policy, people can already measure their own stress without going to the doctor. Entrepreneurs are making money out of people's desire to test their stress levels. Devices are on sale that measure hormones, blood pressure or pulse rates.
