Heat Risks for Infants and Young Children
Human-caused climate change is lengthening and intensifying heat waves across the United States, most recently producing a nationwide “heat dome.” Pediatric experts explain that babies and toddlers are especially vulnerable because they sweat less, have higher metabolic rates, and possess a larger surface-area-to-mass ratio that accelerates heat absorption. Their tendency to spend more time outdoors further raises the risk of dehydration, irritability, fatigue, flushed skin, and, in severe cases, heat-related illness.
Pediatric Recommendations
Dr. Katherine Williamson of Rady Children’s Health in Orange, California, advises parents to avoid the hottest parts of the day, dress children in loose, light-colored clothing, apply sunscreen, and ensure frequent fluid intake—including water-rich fruits such as watermelon and strawberries. She notes that a lack of tears or wet diapers can signal dehydration, while increased irritability may indicate overheating. Dr. Debra Langlois of the University of Michigan Health C.S. Mott Children’s Hospital adds that limiting outdoor time is prudent, though she does not recommend staying strictly indoors.
Vehicle Heat Safety
Even in shade, parked cars can reach dangerous temperatures within minutes. The National Highway Traffic Safety Administration reports that 31 children died of heat stroke in vehicles in 2025. Caregivers are urged to leave a personal item or a stuffed animal on the passenger seat as a reminder not to leave a child inside, to use sun shades, pre-cool the interior with air conditioning, and to check that metal car-seat components are not too hot before placing a baby in them.
Key Statistics
- 31 child heat-stroke deaths in vehicles (2025, NHTSA).
