Music may improve productivity "just because" it improves mood, rather than directly affecting cognitive performance. Recent studies have shed light on the effects of music on concentration and work productivity, with most researchers agreeing that music's effect depends on how much the listener actually enjoys the music. Listening to music activates the brain's reward system, releasing dopamine, which can help train the brain to associate a positive behavior with a hormonal reward. Background noise, such as white noise or nature sounds, has also been shown to increase productivity for creative tasks and reduce stress levels. Ultimately, the best approach is to listen to what makes you feel good, avoiding music with lyrics that might be distracting, and opting for ambient nature sounds if needed.
