A new study from Northwestern University, published in the Journal of Women’s Health, provides the first systematic data on the frequency and circumstances of "peri-orgasmic phenomena," surprising reactions that can occur during orgasm. These phenomena, which include unexpected laughter, tears, hallucinations, or physical pain, are not isolated incidents but rather occur with notable regularity. The research aims to clarify how common these experiences are and whether they warrant concern for individuals undergoing them, offering a scientific perspective on previously anecdotal observations of unusual orgasmic responses.
