Concepts: Physiology of Stress

• Sympathetic Nervous System (SNS): basis of fight or flight response, releasing adrenaline and nonadrenaline, priming the body for physical activity (which also shuts down proteins involved in fighting viruses)
• Stress in children leads to eosinophils, creating mucus, constrict airways and result in a shortness of breath
• Cortisol: higher production with a lack of certainty over what the future holds
