You’re restless, fatigued and tense. You’re preoccupied with worry and trying to control those intrusive thoughts, but nothing seems to work. But what if we told you that you could just put on your headphones and listen to a song and feel instantly better? We wouldn’t be lying. There is actually a song created specifically for that purpose, and its efficacy is backed by science. United Kingdom-based band Marconi Union composed their song “Weightless” to help treat the most common mental illness in the U.S. Anxiety is a condition that affects 40 million adults living in the U.S. That’s 18 percent of the population. The musical trio collaborated with sound therapists to carefully arrange harmonies, rhythms and bass lines that help slow a listener’s heart rate, reports Inc. The song also helps to reduce blood pressure and lower cortisol, a stress hormone. “Weightless” came out as the top song that produced a greater state of relaxation over any other music tested to date. Participants who listened to the song experienced a 65 percent reduction in overall anxiety and a 35 percent reduction in their usual physiological resting rates, according to Dr. David Lewis-Hodgson of Mindlab International.
