How the Body Reacts to Sexual Intimacy
During sexual intimacy, the body triggers dopamine, boosting mood and pleasure. Cortisol and adrenaline are lowered which reduces the stress hormones and causes relaxation to fill the cells of the body with a sense of calmness. The hormone oxytocin increases and sends a euphoric sensation throughout the body and mind. This increases the intimacy and closeness that we feel with our partner, relaxes the body, and improves a high-quality sleep. The heart rate increases momentarily, which benefits vascular health. An increase in immunoglobulin A (IgA) helps to boost the body’s overall immunity while testosterone and estrogen are triggered, which helps bone and soft tissue health.
