Getting enough sleep is essential to good health, but millions of people struggle with it. As a result, many of us turn to calming music in the hopes that it will lull us to sleep. While music won't cure your insomnia, it can provide short-term relief. Studies show that listening to music before sleep might improve sleep quality. So which tunes are actually the most helpful? The answer depends largely on the person, but there are a few guidelines you should follow. First, lyrics are a no-go, as they're likely to spur our brains into more activity. Experts recommend listening to instrumental music instead, particularly tracks that rely on low instruments like the cello or the double bass. It's also good to keep tempo in mind, researchers recommend songs between 60 and 80 beats per minute.
