1Hena Khan is a ninth-grade student in Dhaka, Bangladesh.
2She struggled to keep attention on her studies last week as temperatures rose above 43 degrees Celsius in Bangladesh's capital.
3"There is no real education in schools in this punishing heat," she said.
4"Teachers can't teach, students can't concentrate. Rather, our lives are at risk."
5Khan is one of more than 40 million students who have been shut out of classrooms in recent weeks.
6Heatwaves have forced school closures in parts of Asia and North Africa.
7As the climate warms due to the burning of fossil fuels, heatwaves are lasting longer and reaching higher temperatures.
8Government officials and public health experts across the world are increasingly struggling with whether to keep students learning in hot classrooms.
9Either decision has impacts.
10About 17 percent of the world's school-aged children are already out of school, says the United Nations.
11But the proportion is much larger in developing countries.
12Test scores in the developing world also behind developed countries.
13Heat could worsen inequalities by widening learning gaps between wealthy countries and poor nations in the tropics, experts told Reuters.
14It could even worsen inequalities between rich and poor areas in wealthy countries.
15Sending children to hot schools can also make them sick.
16Earlier this spring, heat-related school closures in South Sudan affected over 2 million students.
17Temperatures rose to 45 degrees Celsius there in late March.
18Thousands of schools in the Philippines and in India closed schools in late April, impacting more than 10 million students.
19Last week, Cambodia ordered all public schools to cut two hours off the school day to avoid the peak heat at midday.
20Bangladesh has debated whether to close schools for about 33 million students.
21Temperatures there are rising to dangerous levels.
22Many Bangladeshi schools "don't have fans, the ventilation is not good, and they... (do) not provide good insulation," said Shumon Sengupta.
23He is Bangladesh country director for the nonprofit organization Save the Children.
24Even if students continue attending classes during heatwaves, their education is likely to suffer.
25High temperatures slow down the brain's functions, lowering students' ability to remember and process information.
26A 2020 study found that American high schoolers performed worse on standardized tests if they were exposed to higher temperatures in the year leading up to the exam.
27The research was published in the American Economic Journal.
28It found that a .55 Celsius degree warmer school year reduced that year's learning by 1 percent.
29Schools with air conditioning did not feel those same effects, said study co-writer Josh Goodman. He is an economist at Boston University.
30Goodman and his research partners found similar learning results tied to heat when they looked at standardized test data in other countries.
31"When (students in) these places experience a year with more heat, they appear to have learned less," he said.
32Other research suggests high heat in the tropics can also impact a child's education even before birth.
33Children in Southeast Asia exposed to higher-than-average temperatures in utero and early in life received fewer years of schooling later in life.
34That information comes from a 2019 study in the Proceedings of the National Academy of Sciences.
35Goodman said as the world warms, already hot countries that become extremely hot countries will suffer more than cooler countries.
36"Climate change will widen the learning gaps between hot and cool countries," Goodman said.
37Some developed countries are trying to find solutions to the issue.
38In March, the U.S. Agency for International Development (USAID) announced it would build 30 heat-resilient schools in Jordan by 2026, a USAID spokesperson said.
39Heat-resilient buildings can remain comparatively cool in very hot weather.
40USAID said it would spend $8.17 million on the schools.
41The schools would have special cooling systems and air conditioning.
42The number of days that schools are closed for extreme heat has been increasing in the United States.
43Few countries record such data.
44In Bangladesh last year, schools were closed for 6 to 7 days, said Save the Children's Sengupta.
45"But this year, they are saying it might be closed for 3 to 4 weeks," he said.
46May is often the hottest month in South Asia.
