Cognitive performance of undergraduate students increased at an air temperature of approximately 23.3°C, with an initial mean BP of 93.33 mmHg and a 60 bpm HRmax.

Do temperature changes in classrooms affect blood pressure, heart rate, and cognitive performance in university students?
Optimal cognitive performance in students occurs at an air temperature of approximately 23.3°C, interacting with baseline mean blood pressure and maximum heart rate.
BACKGROUND: The increase in air temperature has been associated with human deaths, some of which are related to cardiovascular dysfunctions, and with the reduction of physical and cognitive performance in humans. OBJECTIVE: To analyze the relationship between blood pressure (BP) and heart rate (HR) and the cognitive performance of students who were submitted to temperature changes in classrooms. METHODS: The university students answered a survey that was adapted from the Battery of Reasoning Tests over 3 consecutive days at different air temperatures while their thermal state and HR were measured. During those 3 days, BP and HR were evaluated before and after the cognitive test. RESULTS: The average and final HR increased at high temperatures; the tests execution time was reduced at high temperatures; and the cognitive tests was related to Mean BP at the beginning of the test, the maximum HR during the test and the air temperature. CONCLUSIONS: The cognitive performance of undergraduate students in the field of engineering and technology will increase while performing activities in a learning environment with an air temperature of approximately 23.3°C (according to their thermal perception), if students have an initial MBP of 93.33 mmHg and a 60 bpm HRmax.
