What helps people live longer and healthier lives? Is it a balanced diet, regular exercise, or good genetics? While all of these factors matter, one of the world's longest-running studies on human happiness suggests that another ingredient may be just as important: the quality of our relationships. Now, decades after the landmark Harvard Study of Adult Development first began in 1938, scientists are uncovering new clues about why close relationships have such a powerful influence on health and longevity. Emerging evidence suggests that one overlooked factor— affectionate, consensual touch —may help explain why people in supportive relationships are better equipped to cope with the pressures of modern life.
Launched in 1938 during the "Great Depression", the Harvard Study of Adult Development has followed the lives of more than 700 participants over several decades, making it one of the longest-running investigations into human health and wellbeing. Its findings have remained remarkably consistent. Participants who enjoyed warm, supportive relationships generally experienced better physical health, greater emotional wellbeing, and longer lives than those who felt isolated or disconnected.
