July 29, 2020 An earlier post suggested that COVID-19 lockdowns create a ‘perfect storm’ of vulnerabilities that huge numbers of people, and services, are ill-prepared to manage.  I reviewed the science of human needs as they are expected to play out over prolonged periods of domestic confinement. More details were published in our article in the Journal of Health Psychology. Psychological homeostasis is a natural ability to maintain stability,Continue reading “Mood Homeostasis in COVID-19 Lockdown”
