Anyone who has ever entrusted a troubling secret to a journal, or mourned a broken heart with a friend, knows the feeling of relief that expressing painful emotions can bring. This book presents astonishing evidence that personal self-disclosure is not only good for our emotional health, but boosts our physical health as well.

Pennebaker sheds new light on the powerful mind/body connection. Dr Pennebaker asks ordinary people to discuss their most difficult memories - including traumatic experiences they have never revealed to a soul - and traces the medical effects of this disclosure. The book interweaves the resulting data with insightful case studies on secret-keeping, confession and the hidden price of silence.Filled with information and encouragement, Opening Up explains: Why suppressing inner problems takes a devastating toll on health How long-buried trauma affects the immune system How writing about your problems can improve your health Why it's never too late to heal old emotional wounds When self-disclosure may be risky - and how to know whom to trust This book would appeal to readers interested in understanding the relationship between emotional and physical health, and in minimizing the harmful effects of stress. Written for a general audience, the book also contains much of value to practitioners and students of psychology and psychotherapy.
