The evolution of virtual reality (VR) technologies requires setting boundaries of its use. In this study, 3 female participants were experiencing VR scenarios with stressful content and their activity of the autonomic nervous system and EEG were recorded. It has been discovered that virtual reality can evoke acute stress reactions accompanied by activation of the sympathetic nervous system and a decrease in the activity of the parasympathetic nervous system. The high-stress response is accompanied by a decrease in the power of the EEG, and, on the contrary, the activation of the avoidance reaction is accompanied by an increase in the power of the EEG alpha waves. Therefore, the use of stressful VR content can cause high emotional stress to a user and restrictions should be considered.

过于真实以至于无法虚拟：对虚拟现实中极端压力场景的自主性和EEG响应

虚拟现实（VR）技术的发展需要设定其使用范围。在这项研究中，3名女性参与者正在经历带有压力内容的VR情景，并记录了他们的自主神经系统和EEG的活动。已经发现，虚拟现实可以引起急性应激反应，伴随着交感神经系统的激活和副交感神经系统活性的降低。高应力反应伴随着脑电图功率的降低，相反，回避反应的激活伴随着脑电图α波功率的提高。因此，紧张的VR内容的使用会给用户带来很大的情绪压力，应考虑限制。
