A theory revolves around the idea that music is represented in multiple parts of the brain and therefore accesses deeper pathways between neurons. Music then helps patients connect the stored knowledge of words through songs and helps create the new connections needed for speech. This same idea has been used for stroke victims in the past. When you listen to music you know, it stimulates the hippocampus, which handles long-term storage in the brain. Doing so can also bring out relevant memories you made while listening to a particular song.
In a recent study, researchers found a positive correlation between fast paced music and exercise. While it’s nothing too surprising, music works to increase exercising strength by distracting attention and pushing the heart and muscles to work at a faster pace. The best music to listen to is between 120-140 beats per minute, which also happens to be the standard tempo for upbeat dance music, meaning you’ll be increasing your immune system and helping you exercise at the same time.
