Aside from the benefits we receive from listening to music for enjoyment and release, listening to music can be a good alternative to pharmaceuticals for those having trouble with sleep (with none of the side effects that sleep-aid drugs bring). There are even musical therapists who can administer sound-based therapies if one so desires, and research has shown it may improve sleep in those struggling (even more so than audiobooks). Equal in power to hypnotic sedatives, music for sleep is a form of self-care that is easy to utilize. According to research, the music that is most effective in inducing sleep is classical, ambient, meditation, and lullabies, mostly due to the slow tempo or moderate changes in tempo.
