Lower social status heightens biological stress responses, study finds
A new comprehensive meta-analysis suggests that feeling lower in social rank due to socioeconomic factors like income or education can intensify the body’s cardiovascular stress responses. By pooling 25 laboratory studies with over 2,000 participants, researchers found that simply being led to feel lower in socioeconomic standing can trigger stronger heart and vessel reactions to stress. Yet the same effect did not emerge when social rank was manipulated through brief performance challenges. The findings point to a plausible biological pathway by which social inequality could contribute to higher heart disease risk over time, while also raising questions about how different ways of signaling social status shape our bodies. The research, conducted by a team at the University of Alabama and published in Health Psychology, highlights that not all cues of threat to status are equal in their physiological impact, a nuance with important implications for health equity in Thailand and beyond.
