The fellowship answer

Children feel climate heat first and hardest. In clinic, that means two jobs at once. First, prevent and treat heat illness: know the spectrum from cramps to heat stroke, and when mental status changes cool immediately — cold-water immersion when you can, then ABC and hospital care. Second, counsel families and schools for heat waves, sports acclimatisation and “never leave a child in a car,” while naming climate change as a child-health equity issue, not a political aside. [1] [3] [5] [6] [7]

Overview & Definition

A coach calls from the sideline: a 15-year-old collapsed in the first week of preseason training. The air is humid. The child is confused. That is not “just dehydration.” That is heat stroke until you prove otherwise, and the clock is running on brain and organ injury. [6] [7]

Climate change raises the frequency and intensity of heat extremes and stacks other child-health threats on top — worse air quality days, wildfire smoke, shifting infections, food and housing stress, and disaster displacement. The American Academy of Pediatrics (AAP) frames this as a paediatric emergency across the life course, from fetal life through adolescence. [1] [2] [3] [4]

Heat illness is the clinical spectrum of body-temperature stress: cramps, heat syncope, heat exhaustion and heat stroke. Heat stroke is the emergency end: hyperthermia plus central nervous system dysfunction after heat exposure or exertion. You treat the syndrome, not a single thermometer reading in isolation. [6]

This page teaches the bedside ladder, the cool-first algorithm, and the preventive and advocacy work that keeps the next child off that ladder. [5] [13]

What you say in clinic or on the field

"If a child is confused, seizing or collapsed in the heat, we cool first — ideally in cold water — then move to hospital care. For every family before summer: drink often, use shade, cut hard sport in extreme heat, and never leave a child in a parked car." Then ask what their school or club actually does on a 38 °C day. [5] [7]
