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.
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.
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.
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.
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.
气温升高与人类死亡有关，其中一些死亡与心血管功能障碍有关，还与人类身体和认知能力的下降有关。
分析教室温度变化时学生的血压（BP）、心率（HR）与认知能力之间的关系。
大学生连续3天在不同气温下回答一份改编自推理测试组合的调查问卷，同时测量他们的热状态和心率。在这3天里，认知测试前后评估血压和心率。
高温下平均心率和最终心率增加；高温下测试执行时间缩短；认知测试与测试开始时的平均血压、测试期间的最高心率和气温有关。
如果工科和技术专业本科生的初始平均血压为93.33 mmHg，心率最大值为60次/分钟，那么在气温约为23.3°C（根据他们的热感知）的学习环境中进行活动时，他们的认知能力将会提高。
