Cognitive and Mental Health Improvement Under- and Post-COVID-19 - Volume II

This Research Topic is a part of a collection on the topic of Cognitive and Mental Health Improvement Under- and Post-COVID-19 An increasing body of research suggests that the COVID-19 pandemic has worsened global mental health and caused more cognitive impairments. Whereas the COVID-19 pandemic is still ongoing in some regions, it is expected to be ending for most regions in the very near future. From a psychological, psychiatric, and public mental health perspective, it is of vital importance to conduct effective and efficient interventions to promote cognitive and mental health, for they not only are essential for us to cope with the ongoing pandemic, but also necessary for us to rebuild a better world post-the pandemic. Not to say that a healthy cognitive and mental health state is at the core of human wellbeing and deserves its own place. From previous studies and everyday practices, we already know that regular exercise, appropriate sleep, nutritious diet, close social ties, connection with nature, mindfulness, among others, help improve cognition and boost mental health. However, the optimal regimen for each specific cognitive and mental health outcome for a specific population, including both those of healthy and clinical, is unclear and remain to be identified. Furthermore, the underlying psychological, physiological, and neurobiological mechanisms through which each activity or intervention improves cognition and promotes mental health are to be clarified.
