Millions of people in cities rely on recorded nature sounds to manage sleep and stress, and scientists are slowly understanding why it works. At Shahed University in Tehran, Iran, a group of researchers found that listening to natural sounds relieved patients in the ICU of their anxiety, while lowering their heart rate and blood pressure. Researchers in Japan’s Osaka City University Medical School found that patients listening to natural sounds showed an improved acceptability to anesthesia, while Johns Hopkins University in Baltimore reported that distraction therapy using nature sounds reduced the amount of pain people experienced during bronchoscopies.
