Climate models predict that the global average temperature of Earth will rise in the
future. Studies show that high classroom temperatures can a ect the ability of the student to learn
and function. It is important to understand the impact that heat will have on the health, wellbeing,
and academic performance of learners, as they spend a significant amount of time in classrooms
compared to any other environment. A follow-up panel study among 20 public primary schools in
the Gauteng province (South Africa) will be carried out, in which Grade 4 learners will be selected
to complete an hourly heat-health symptom questionnaire. A Cambridge Neuropsychological Test
Automated Battery (CANTAB) test will be used to determine their memory and attention span.
A nursing practitioner will measure body weight, height, and temperature. Lascar data loggers will
be used to measure indoor classroom temperature. School principals will complete a questionnaire on
existing school coping mechanisms and policies in place that help deal with hot weather conditions.
This is the first study to quantitatively assess the e ects of heat on learners’ health, well-being and
school performance in South Africa. The outcomes of this study will enable policymakers and public
o cials to develop appropriate school heat adaptation and mitigation measures and will assist in
channeling their resources where it is most needed.
