Submissive mice live shorter than dominant mice as a consequence of social stress
Social stress linked to shorter life span in mice - health science news

Mice holding a low position on the hierarchical ladder suffer from social stress imposed by dominant conspecifics. These socially stressed mice show earlier onset of neurodegenerative and cardiovascular diseases, a new study shows. They are also at a higher risk than dominant mice of developing cancer. These pathologies coincide with age-related pathologies, and stressed mice indeed have a lower lifespan. These findings parallel observations in humans, where low social and economic status increase the risk of disease and mortality. With the new animal model, researchers aim to increase our understanding of the processes underlying the negative influences of social stress on human health.
