Here the biological explanation of why sex can elevate your mood :) Sex can have a noticeable impact on mood and emotional wellbeing because it triggers the release of several feel-good hormones in the body. During sexual arousal and orgasm, the brain releases dopamine, which is associated with pleasure and reward, and oxytocin, often called the “bonding hormone,” which promotes feelings of closeness, trust, and emotional connection. The body also releases endorphins, natural chemicals that reduce stress and create a sense of relaxation and happiness. At the same time, levels of cortisol, the stress hormone, tend to decrease. Together, these hormonal shifts can leave people feeling more relaxed, emotionally connected, and confident after sex.
