March 1 st 2021, the COVID-19 pandemic caused over 2.5 million deaths worldwide. To restrict spreading of the virus, movement was restricted. At the outbreak of the pandemic, there were concerns for poor mental health in both the immediate and long-term future. Encouraging people to use strategies to regulate the emotions of others and self is therefore worthwhile. In this chapter, I look at how the pandemic affected emotion and the use of emotion regulation strategies guided by the Gross and Thompson (2007) five-family model. Strategies people typically used were often not available or easy to do in lockdown, and so careful planning was necessary. A reflective case study that describes an emotion regulation strategy via a physical challenge is described. The case study outlines how setting an exciting challenge and how sharing progress can influence the emotions of others and self. In summary, active planning of emotion regulation strategies that you do is worth considering for managing emotions and mood, which help maintain positive mental health.
