Scientific research links physical affection and social connection to mental health

Recent scientific studies and reports highlight the significant impact of physical affection and social connection on emotional well-being. Research published in the Journal of Public Health involving over 3,000 adults in Germany found that individuals who hug at least one person daily show a 35% lower relative probability of depressive symptoms and a 27% lower probability of anxiety compared to those who do not.

A review of 137 studies published in Nature Human Behaviour also indicates that physical contact interventions are associated with reductions in pain, anxiety, and depressive symptoms in adults. While the hormone oxytocin is often linked to these social bonds, researchers note that current evidence is insufficient to claim that increasing oxytocin levels can delay aging or extend life.

Beyond physical touch, experts emphasize the importance of quality social interactions, such as face-to-face conversations without digital distractions. The World Health Organization has noted the growing global challenge of social isolation, with 2025 reports indicating that one in six people worldwide experiences loneliness. Strong social ties are consistently associated with better health indicators and a reduced risk of premature death.
