Concept
Stress in early childhood
Summary
Early childhood is a critical period in a child's life that includes ages from conception to five years old. Psychological stress is an inevitable part of life. Human beings can experience stress from an early age. Although stress is a factor for the average human being, it can be a positive or negative molding aspect in a young child's life.
A certain amount of stress is normal and necessary for survival. A few stressors can be manageable for young children; stress can be beneficial by helping children develop skills needed to adapt to a new set of circumstances and deal with dangerous and intimidating situations. Some experts have theorized that there is a point where prolonged or excessive stress becomes harmful and can lead to serious health effects. When stress builds up in early childhood, neurobiological factors are affected. In turn, levels of the stress hormone cortisol exceed normal ranges. This theory however is based on animal studies and cross-sectional studies in humans, and the proposed impacts on brain centers have not been found in a landmark twin study and studies where neurobiological factors were measured in humans prior to stress or trauma exposure.
Researchers have proposed three distinct types of responses to stress in young children: positive, tolerable, and toxic. These labels are based on theorized differences in lasting physiological changes occurring as a result of the intensity and duration of the stress response.
Stress is caused by internal or external influences that disrupt an individual's normal state of well-being. These influences are capable of affecting health by causing emotional distress and leading to a variety of physiological changes. Internal stressors include physiological conditions such as hunger, pain, illness or fatigue. Other internal sources of stress consist of shyness in a child, emotions, gender, age and intellectual capacity. Childhood trauma has lifelong impact.
