A highly sensitive person (HSP) is a term for those who have an increased central nervous system sensitivity to physical, emotional or social stimuli. High sensitivity is not a 'condition', it is a normal human trait. This book explores what it means and feels to experience life as a highly sensitive person. HSPs comprise about a fifth of the human population, both male and female, although it may be less observable in the behaviour of many males because of upbringing and cultural stereotypes. One of the greatest pains for anyone is to feel thwarted in their ability to contribute and communicate.
