The aim of the present study was to analyze the impact of surgical mask use in cognitive and psychophysiological response of university students during a lesson. We analyzed 50 volunteers university students (age 20.2 ± 2.9) in two 150 min lessons. i. personal class using a surgical mask and ii. online class with student at home without the mask. Blood oxygen saturation, heart rate and heart rate variability, mental fatigue and reaction time were measured before and immediately after both lectures. We found how both lesson produced an increase in mental fatigue, reaction time and autonomous sympathetic modulation, being heart rate significantly higher (77.7 ± 18.2 vs. 89.3 ± 11.2 bpm, not mask, mask respectively) and blood oxygen saturation significantly lower (98.4 ± 0.5 vs. 96.0 ± 1.8%, mask, not mask respectively) using the surgical mask. The use of surgical mask during a 150 min university lesson produced an increased heart rate and a decrease in blood oxygen saturation, not significantly affecting the mental fatigue perception, reaction time and time, frequency and nonlinear hear rate variability domains of students.
本研究的目的是分析在一堂课期间佩戴外科口罩对大学生认知和心理生理反应的影响。我们在两堂150分钟的课程中分析了50名志愿者大学生（年龄20.2±2.9岁）。i. 个人课堂，学生佩戴外科口罩；ii. 在线课堂，学生在家不戴口罩。在两堂课开始前和结束后立即测量血氧饱和度、心率和心率变异性、精神疲劳和反应时间。我们发现，两堂课都会导致精神疲劳、反应时间和自主交感神经调节增加，使用外科口罩时心率显著更高（分别为不戴口罩时77.7±18.2次/分钟，戴口罩时89.3±11.2次/分钟），血氧饱和度显著更低（分别为戴口罩时96.0±1.8%，不戴口罩时98.4±0.5%）。在150分钟的大学课程中佩戴外科口罩会导致心率增加和血氧饱和度降低，但对学生的精神疲劳感知、反应时间以及时间、频率和非线性心率变异性领域没有显著影响。
