Extreme heatwaves are slowing children’s early development: Here’s how

The researchers in a recent study have found a disturbing link between scorching heatwaves and their damaging impact on childhood development.

According to findings published in the Journal of Child Psychology and Psychiatry, increasing temperatures exceeding above 86 °F (30 °C) are likely to hinder children’s learning and growth capabilities.

As per evidence, the children who inhabit unusual warm areas are less likely to achieve numerical and literacy milestones as compared to kids who live in cool environments.

According to lead author Jorge Cuartas, assistant professor of applied psychology at NYU Steinhardt, "While heat exposure has been linked to negative physical and mental health outcomes across the life course, this study provides a new insight that excessive heat negatively impacts young children's development across diverse countries.”

Given the importance of childhood development, it is hard to rule out its crucial role in lifelong learning, physical and mental wellbeing.

“These findings should alert researchers, policymakers, and practitioners to the urgent need to protect children's development in a warming world,” Cuartas added.

The study led by Cuartas and his team, examined data from 19,607 children aged three and four across six diverse, low-to-middle-income countries, including Gambia, Georgia, Madagascar, Malawi, Palestine, and Sierra Leone.

The team also used the Early Childhood Development Index (ECDI) to track the development in four key domains, such as social-emotional development, literacy and numeracy achievements, physical development, and approaches to learning.

The negative impacts were the most prominent among children belonging to economically disadvantaged households, densely populated urban areas, and homes having restricted access to food and clean water.

"We urgently need more research to identify the mechanisms…Such work will help pinpoint concrete targets for policies and interventions that strengthen preparedness, adaptation, and resilience as climate change intensifies," Cuartas added.
