Harvard professor Dr. Jack Shonkoff has long studied this area of research at the Center on the Developing Child at Harvard’s Chan School of Public Health.14 He has defined three possible ways we can respond to stress: positive, tolerable, and toxic. As described below, these terms refer to the stress response system’s effects on the body, not to the stressful event or experience itself: A positive stress response is our built-in biopsychosocial skills that enable us to deal with daily stressors. Indeed, this positive stress response is akin to how we’ve been characterizing good anxiety—a brief increase in heart rate and mild elevations in hormone levels. A tolerable stress response is marked by an activation of the body’s inner alarm system provoked by a truly frightening or dangerous encounter, the death of a loved one, or a big romantic breakup or divorce. During such intense stress, the brain-body can offset the impact through conscious self-care, such as turning to a support system. The key here is that the person’s resilience factor is already stable enough to enable the recovery. If, for instance, someone is faced with a life crisis and they don’t have a strong resilience factor, then they will be less able to recover and bounce back. A toxic stress response occurs when a child or adult undergoes ongoing or prolonged adversity—such as poverty, abject neglect, physical or emotional abuse, chronic neglect, exposure to violence—without sufficient support in place. This kind of prolonged activation of the stress response systems can not only disrupt the development of brain architecture and other organ systems of the child but also lingers well into adulthood, robbing people of their ability to manage any kind of stress.
