Recently, studies have revealed that individuals who have survived a COVID-19 infection may experience a range of persistent symptoms (Comelli et al., 2022; Nalbandian et al., 2021), indicating that the pandemic is far from over and its aftermath is difficult to eliminate completely. At the same time, the COVID-19 pandemic has presented unprecedented challenges for nurses around the world. Not only are they at the forefront of preventing and controlling the spread of the virus, but they are also the primary caregivers for patients experiencing the after-effects of the pandemic. Meanwhile, they also need to care for the patients with other illness. Some study evidence indicated that there is a shortage of nurses during the COVID-19 pandemic, and nursing staff are experiencing a high level of negative emotions (Jiang et al., 2022; Zhang et al., 2022).~The ongoing pandemic has had a huge impact on the mental health and work of nurses (Chen et al., 2021). Between 40% and 66.7% of surveyed health care workers reported mental health problems during the pandemic, according to a report by the OECD (Organisation for Economic Development and Cooperation, 2021). The stress caused by COVID-19 has contributed to workforce attrition, with many nurses opting to leave the profession (Organisation for Economic Development and Cooperation, 2021; World Health Organization, 2022). It has taken a heavy toll on the healthcare system. Maintaining the mental health of nurses is crucial. This is not only conducive to pandemic prevention and control, but also plays a significant role in the normal medical order.
Mindfulness-based stress reduction (MBSR), a widely used method to improve mental state and sleep quality, was developed by Kabat-Zinn in 1970. The meditation of MBSR is effective in regulating patients' emotions, leading to reduced stress, pain, and psychological symptoms. Studies have demonstrated that MBSR has a positive impact on multiple psychological and physical symptoms in a variety of cancers. On this basis, investigators found that VR treatment can also help patients relax, and it has been widely used in cancer symptom relief in recent years. VR treatment involves using headset devices that fully restrict the vision field to content displayed inside the headset screen; As a treatment modality, VR provides a unique environment comprising 3D visually immersive experiences that are enriched with stereo sounds and elements such as rich colors and scenic environments that enhance elicitation of desired states of arousal and affect. Within the therapeutic context, VR may be flexibly designed and tailored to address the needs of specific conditions (eg, anxiety, depression, pain) auditory perception is not fully restricted, though the corresponding device-delivered auditory content commands attention.
