Being in a romantic relationship or engaging in physical contact (hugging) can alter your gene expression by activating repair genes and deactivating inflammation.

This claim is based on the emerging field of psychobiology and social epigenetics. Studies, particularly those published in *Psychoneuroendocrinology* (observational and interventional studies), show that social support and positive relationships influence inflammatory markers like C-reactive protein (CRP) and the expression of genes related to the immune response. It is well-established that chronic stress activates pro-inflammatory genes (CTRA response), and that soothing interactions can modulate this response. However, the use of the term 'alter your gene expression' is scientifically accurate but often misinterpreted as a permanent or magical transformation. In reality, these are dynamic and reversible regulations dependent on the environment, not a fundamental reprogramming of DNA. The idea that love is 'medicine' is a powerful metaphorical simplification that reflects the real impact of social ties on stress biology, although it does not replace medical treatments for confirmed inflammatory conditions.
