Music can influence people's emotions and health in several ways. It can help relax the body, change moods, and aid sleep. Different types of music, such as classical, are found to positively influence brain waves and physiology. Certain rhythms and frequencies from some songs may also impact health and potentially cause stomach pain or mental issues if coinciding with brain frequencies. Overall, listening to music can benefit the cardiovascular system, lower stress, and even help prevent hearing loss.
