Orgasm involves a series of physiological responses, including increased heart rate, muscle contractions, and a wave of relaxation throughout the body. This process is accompanied by the release of various hormones such as oxytocin, endorphins, serotonin, dopamine, and prolactin, which affect sleep, stress, and pain. These hormones contribute to a state of calm and well-being following orgasm. Endorphins secreted during orgasm can partially block pain signals, particularly for menstrual or joint pain. However, these effects do not replace medical treatment for chronic pain, sleep disorders, or established depression. The release of adrenaline and noradrenaline, along with oxytocin, serotonin, dopamine, and prolactin, creates a cascade of substances that influence various bodily functions. Recent observations suggest that sexual activity accompanied by an orgasm may improve certain sleep parameters by reducing the time spent awake after falling asleep. The oxytocin and prolactin released during orgasm may promote a more serene falling asleep. Additionally, endorphins secreted during orgasm can influence the perception of pain, partially blocking pain signals while increasing the feeling of well-being. These peptides are also found during intense physical effort, which explains why they inhibit muscle cramps and certain types of pain. Regarding stress, oxytocin may lower cortisol levels, a hormone associated with stress. In women, some observations have noted reduced activity in the amygdala, the brain area linked to fear and anxiety, during orgasm. While orgasm has real benefits, it is not a substitute for medical treatment. Persistent pain, chronic sleep disorders, or established depression require appropriate support. The absence of orgasm, or anorgasmia, is a frequent reason for consultation and may raise questions about the relationship to sexuality, the ability to let go, control, or even the family history and environment of the patient. It is also essential to distinguish the complaint of the person concerned from that of the partner, as an almost obsessive quest for the partner's orgasm may sometimes hide a personal need for reassurance rather than a real concern for shared pleasure. The hormonal cocktail released during orgasm does indeed act on the body, between muscle relaxation, mental relaxation, and the alleviation of certain pains.
