US parents urged to protect babies during extreme heat waves

Intensified heat waves across much of the United States, driven by human‑caused climate change, have raised concerns for infants and toddlers. Pediatricians Dr. Katherine Williamson of Rady Children’s Health in Orange, California, and Dr. Debra Langlois of the University of Michigan Health System warn that children are more vulnerable because they sweat less, have higher metabolism and a larger surface‑area‑to‑mass ratio.

Signs of heat‑related illness include lack of tears, fewer wet diapers, fatigue, flushed skin and increased irritability. Parents are advised to avoid the hottest parts of the day, dress children in loose, light‑colored clothing, apply sunscreen, keep them well‑hydrated with water‑rich fruits such as watermelon and strawberries, and limit outdoor exposure. Blankets or other covers on strollers should be avoided because they trap heat.

The guidance aims to help families keep infants safe as heat domes and longer, stronger heat events become more common.
