In the face of the new Crown Pneumonia epidemic, how should returning staff improve their psychological immunity? Firstly, we should learn about disease prevention and control, do a good job of personal protection, and avoid excessive anxiety. Secondly, those who return to work should actively adapt to the new mode of work, in the workplace, to comply with the unit’s protection requirements, telecommuting, as soon as possible to learn and adapt to the online mode of work, both sides to strengthen communication and integration, to reduce the change in the mode of work brought about by the tension and anxiety. For those who work at home, it is recommended to demarcate the boundaries between work and life in a ceremonial way, such as waking up on time, dressing neatly, finding a place as quiet as possible as a work area, clearly distinguishing between going to work and going off work, etc., and maintaining smooth communication with coworkers. Finally, try to avoid exposure to content that can easily lead to distraction, such as information on epidemics, in the course of work. When performing critical tasks, you should completely eliminate irrelevant information to ensure that your attention is focused on your work, and be aware of your physical and mental state. In case of excessive fatigue, or if there is a confirmed or suspected patient or a person under medical observation at home, on the one hand, promptly seek help from your leaders or colleagues and ask for a change of duty or a break, and on the other hand, you can seek professional help through hotlines and online consultation. If you have suspected pneumonia symptoms yourself, please seek medical attention promptly.
