All children experience stress, including everyday concerns such as schoolwork and friendships. Experts consider this type of stress normal and potentially beneficial for growth, especially when children have support from caregivers or adults.
However, some children face toxic stress, which involves prolonged or traumatic experiences like abuse, family conflict, or living in violent or impoverished environments. This kind of stress can disrupt a child’s developing stress response system and lead to long-term mental and physical health challenges.
Research highlights that adverse childhood experiences (ACEs)—including harmful events or lack of nurturing—are common; about two-thirds of adults recall at least one ACE, and nearly one in six report four or more. ACEs have been linked to higher risks for conditions such as heart disease, diabetes, obesity, stroke, anxiety, depression, and substance use disorders.
Importantly, not all children exposed to adversity experience negative health outcomes later in life. Positive factors like safe, stable, and supportive relationships can help buffer the harmful effects of early life stress.
Scientists continue to study these dynamics to better understand how early experiences shape long-term health and to identify protective strategies that can support children facing adversity.
