The use of face masks has become ubiquitous. Although mask wearing is a convenient way to reduce the spread of disease, it is important to know how the mask affects our communication via facial expression. For example, when we are wearing the mask and meet a friend, are our facial expressions different compared to when we are not? We investigated the effect of face mask wearing on facial expression, including the area around the eyes. We measured surface electromyography from zygomaticus major, orbicularis oculi, and depressor anguli oris muscles, when people smiled and talked with or without a mask. Only the actions of the orbicularis oculi were facilitated by wearing the mask. We thus concluded that mask wearing may increase the recruitment of the eyes during smiling. In other words, we can express joy and happiness even when wearing a face mask.
口罩的使用已经变得无处不在。虽然戴口罩是减少疾病传播的一种便捷方式，但了解口罩如何影响我们通过面部表情的交流是很重要的。例如，当我们戴着口罩遇到朋友时，我们的面部表情与不戴口罩时相比是否有所不同？我们研究了戴口罩对面部表情的影响，包括眼睛周围的区域。当人们戴口罩或不戴口罩微笑和交谈时，我们测量了颧大肌、眼轮匝肌和口角降肌的表面肌电图。只有眼轮匝肌的动作被口罩所促进。因此，我们得出结论，戴口罩可能会增加微笑时眼睛的活动度。换句话说，即使戴着口罩，我们也可以表达喜悦和幸福。
