Noise-canceling headphones may lower postoperative nausea

A scientific study revealed that using noise-canceling headphones after surgery helps reduce the incidence of nausea and vomiting experienced by patients following general anesthesia. The study, which involved 192 patients undergoing laparoscopic surgeries, showed that 35% of those who used headphones experienced these symptoms within 48 hours, compared to 52% of those who did not use them, indicating that reducing noise may help alleviate these symptoms. It is possible that loud sounds trigger a stress response in the body, activating the autonomic nervous system, although the exact relationship is still under investigation. Doctors recommend using headphones after surgery based on the patient's condition and the medical team's guidance, and further research is needed to confirm their effectiveness in other types of procedures.
