Cultivating supportive emotional and social relationships, particularly through affectionate gestures like hugging, can modify our gene expression to reduce inflammation and slow aging.

The concept that our social interactions influence our biology is scientifically fascinating and well-founded. Pioneering work in sociogenomics by Steve Cole and George Slavich at the University of California, Los Angeles (UCLA), building on observational studies, demonstrates that social isolation or conflict stimulates the expression of genes linked to inflammation. Conversely, a sense of connection and support is correlated with a decrease in this inflammatory activity. However, asserting that hugging can instantly reprogram the epigenome to activate all regenerative mechanisms is an extrapolation. While physical contact releases oxytocin, which promotes deep relaxation, direct scientific evidence linking a simple hug to stable modifications of our genetic markers is still lacking in humans. Current research instead highlights global effects linked to long-term healthy lifestyle habits and relationships.
