Mood varies from hour-to-hour, day-to-day and healthy mood regulation involves choosing activities that help settle one’s mood. However, in situations where personal choices of activities are constrained, such as during periods of social isolation and lockdown, this natural mood regulation is impaired which might result in depression. New research, published today in JAMA Psychiatry, from the Department of Psychiatry, University of Oxford suggests a new target for treating and reducing depression is supporting natural mood regulation.
This new study looked at 58,328 participants from low, middle and high income countries, comparing people with low mood or a history of depression with those of high mood. In a series of analyses, the study investigated how people regulate their mood through their choice of everyday activities. In the general population, there is a strong link between how people currently feel and what activities they choose to engage in next. This mechanism - mood homeostasis, the ability to stabilise mood via activities - is impaired in people with low mood and may even be absent in people who have ever been diagnosed with depression.
