Introduction: Rising divorce rates globally represent a significant social concern. Among many reasons, the most important are poor communication, accounting for 38% of divorces, while sexual dissatisfaction represents a very high critical contributing factor.
Aim: We examined the role of emotional and physical intimacy in marital stability and the physical and psychological advantages of affectionate communication, physical touch, and intimacy.
Methods: Literature was reviewed to explore reasons for increasing divorce rates, the relationships between intimacy, communication, and successful marital relationships, and the psychological and physical benefits of couples' intimacy. The review also highlights how healthy sexual and emotional relationships contribute to physical well-being, stable mental health, and overall quality of life.
Results: Evidence shows strong beneficial health effects of intimate behaviors between partners, related to neurochemical responses such as oxytocin, dopamine, serotonin, and endorphins, with cortisol reduction. These effects help improve health, reduce cardiovascular disease risk, enhance immune function, improve mental health, reduce anxiety and depression, act as natural analgesia, and improve sleep quality.
Conclusion: Emotional and physical intimacy are essential for marital stability through measurable physiological mechanisms. Physical affection has effects similar to pharmacological interventions. Sexual intimacy significantly affects psychological, emotional, and physical health, contributing to long-term satisfaction and family stability.
