2. Sing for Better Heart Health
Some might say you put your whole heart into karaoke night, however, it turns out that singing actually has rocking (in a good way) affects on your cardiovascular health. Much akin to yoga, a Swedish study found that singing improves heart function essentially by forcing us to take larger, slower, more purposeful breaths.
The 2013 study, published in the journal, Frontiers in Psychology, found that choral singers had slower respiration, which in turn improved their heart rate variability (HRV) and had a biologically soothing effect on overall heart function.
3. Sing to Snore Less
Do your nightly snores, sputters, and sleep apnea have the dog (and your spouse) howling for respite? Luckily, you may find some sleepy solace (for you, your spouse, and the family pet) if you take up singing.
According to a 2008 snoring study published by the U.S. National Library of Medicine those who sing, snore far less. The study monitored the snoring of a group of choral singers and compared them to non-song birds. The study concluded that singers had stronger airway muscles, which drastically reduced the music in the tune of zzzzzzzzzzzz (aka: sawing logs) during sleep.
4. Sing a Tune to Boost Immunity
Even though we are not Disney princesses who sing to cure all of our troubles. Wouldn’t that be nice? However, in real life, research published in the journal, eCancer Medical Science, claims that singing can improve immune function and the body’s ability to lower stress and fight off disease.
The UK study took samples of saliva samples from cancer patients and detected increased cytokines (immune system molecules) and decreased cortisol (stress hormone) in patients who’d recently sang a tune or two. The researchers consider this positive preliminary proof that singing can strengthen immunity.
