Richard Weller is a senior lecturer in Dermatology at the University of Edinburgh. His two areas of study are the role of NO in human skin physiology and the role of skin barrier function deficiencies in atopic disease. In a talk given last year, he discussed an issue dealing with heart disease. Dr. Weller had traveled to Australia, and had noticed that heart disease among Australians was lower than that of Scotland. Not just that, but heart disease among Scots rose the further north you went in the country. Why? He seems to think there is a link between exposure to sunlight and heart disease. Why so?

Apparently, there is a very simple molecule called nitric oxide (NO) that is very important for our cardiovascular health. Number one, it is a vasodilator, which contributes to a lowering of blood pressure. Number two, it dilates the coronary arteries around the heart, which stops angina (chest pain). The skin produces nitric oxide. It also houses more complex molecules, such as NO2, and NO3. Sunlight, in the tests that Dr. Weller performed, seemed to activate these molecules and release nitric oxide into the bloodstream. There was a noticed drop in blood pressure among those human experimentees. The significant thing about those experiments is that the ultraviolet light used on those people was void of vitamin D. He wanted to separate this argument from the vitamin D conversation, because the benefits of vitamin have already been documented. The experiments were solely based on the releasing of nitric oxide into the blood stream. This, according to Dr. Weller, is why heart disease among Australians is so much lower than among the Scottish: the Australians get more exposure to ultraviolet light.

So, there has to be balance in our lives. We know that too much exposure to sunlight causes skin cancer, but some amounts contribute to our health. Where is the happy medium? The scientific community does not seem ready to say as of this time. 

Coincidentally, it was also noted during his talk that green, leafy vegetables are very high in nitrates. If your diet has healthy amounts of such foods, it bodes well for your heart. So eat your vegetables, and try to get yourself some sunlight. Your heart will rest easier, and so will ours.
