A new study from Vrije Universiteit Brussel indicates that one million children in Guatemala are facing significant health risks due to extreme heat. The research highlights the vulnerability of this population to high temperatures. These elevated temperatures pose a direct threat to children’s well-being, potentially leading to heatstroke, dehydration, and other health complications. The study underscores the impacts of climate change on vulnerable populations. Guatemala is increasingly experiencing more frequent and intense heatwaves. This situation requires urgent attention and preventative measures to protect children's health from the worsening effects of climate change.
