- Childhood stress can have lasting impacts on brain development and health. Stress in children is often exhibited through physical, emotional, or behavioral signs. Common causes of childhood stress include parental stress, schoolwork, friendships, sibling rivalry, abuse, illness, and overly packed schedules. Parents can help reduce stress in children by providing a calm and stable home environment, spending quality time together, being attentive listeners, building their child's self-esteem, and teaching relaxation techniques. When stress becomes excessive, seeking professional help may be necessary.
