With all that going on in a sensitive person’s brain, we are easily overstimulated. If I’m travelling and visit a museum during the day, I don’t want to go to a night club that night. Nix to all noisy restaurants. I wear noise-cancelling headsets on planes. I love giving talks about high sensitivity but am totally exhausted afterwards. The more people in the audience, the more exhausted. I am also more sensitive to pain, as that therapist noted early on, causing me to explain that to medical staff: ‘Maybe you’ve noticed with all your professional experience that some people are more sensitive… Me!’
In 2010, after years of research, I boiled all this down to the acronym DOES: ‘Depth of processing, Overarousability, Emotionally responsive and Empathic, and sensitive to Subtle stimuli’. By this definition, about 30 per cent of people have this trait of high sensitivity – and because it is a survival strategy to observe before acting, it’s a trait seen in many. We’ve all met an especially sensitive cat, dog or horse. But there are sensitive birds, fish and fruit flies too.
