A study has described how prolonged exposure to heat -- especially under increased global warming -- can impact cognition of school children, affecting long-term learning and the ability to handle complex tasks.

Researchers from the Royal Melbourne Institute of Technology and University of New South Wales in Australia reviewed data from seven previously published studies involving nearly 14.5 million students from 61 countries, including India.

Findings published in the journal PLOS Climate point to impacted learning capacity of students under a long-term exposure to heat, with performance in complex tasks, such as mathematical, hit harder than that in simpler ones, including reading.
