The COVID-19 epidemic has made access to a healthy lifestyle difficult/challenging because of limited opportunities for individuals to go out and play outside. The new lifestyle that has been adopted in response to COVID-19 is becoming entrenched and is likely to continue for a long time, changing the nature of individuals’ employment and lifestyle. One factor contributing to the negative impact on mental health common to each life stage due to such lifestyles is the “decline in physical activity level”. In this special issue, four experts who are actively conducting research on physical activity, sedentary behavior, and mental health issues in the context of the changes in work and lifestyles that are expected to continue will discuss the actual conditions and relationships among these issues, as well as how they can be resolved and their effects on the mental health of children, adults, and the elderly. They provided content that led to specific solutions for each life stage. With the anticipated long-term effects of the pandemic-related lifestyle, the information provided in this special issue will be useful in addressing and solving issues and problems in the fields of stress science and public health.
