A good deal of science news we've discussed lately in this space has dealt with simple things we too often take for granted -- for one, having a good sense of humor -- that can have a valuable effect on our health.

Much has made about variations of the Mozart Effect, specifically, how exposure to classical music may benefit the health of babies and even adults. To be sure, there's been plenty of debate on both sides about the positive effects humans, especially babies, may or may not experience when surrounded by music, and no clear consensus.

Just to muddy the picture on the plus side, however, a number of reports have surfaced lately about just how music triggers these benefits and they appear to be connected to one's emotions. One study, conducted at the Cleveland Clinic, showed how music lessened activity of individual neurons in the brain and calmed Parkinson's patients during their surgeries.

Another paper suggested a link between a favorite song and one's emotions may actually protect the heart by releasing endorphins from the brain that, in turn, release nitric oxide, a chemical produced by the inner lining of blood vessels called the endothelium that reduces inflammation and allows blood vessels to dilate.

In fact, one expert believes so much in the power of music that he suggests listening to your favorites tunes for up to 20 minutes a day may be as healthy for your body as eating the right foods and exercising.

It certainly can't hurt...
