Friendship makes a difference in stress regulation

ScienceDaily: Latest Science News
A nationwide Dutch study of 100 fourth graders sought to determine whether victimization and exclusion by peers were related to increases in cortisol (a stress hormone), and whether friendships moderated this association. The study found that children who were excluded by their classmates had elevated levels of cortisol at school, indicating that exclusion is stressful. Victimization by classmates wasn't associated with increased cortisol levels, suggesting that victimization is not as stressful as exclusion.
