All of that mental exertion might actually wear a body down: research shows an association between keeping an emotionally charged secret and ailments ranging from the common cold to chronic diseases . Other evidence in favor of disclosure includes multiple studies showing that writing about a traumatic experience can boost the immune system , and the finding that teens who confide in a parent or close friend report fewer physical complaints and less delinquent behavior, loneliness, and depression than those who sit on their secrets
