A report published in the Canadian Medical Association Journal revealed the results of a study conducted by researchers in Greece which found a significant reduction in mortality in several countries during the late summer months of August and September compared with the remainder of the year.*
Researchers at the Alfa Institute of Biomedical Sciences examined mortality statistics for 11 countries for up to 57 years. For the five Mediterranean countries included in the study, September had the lowest average daily mortality. August emerged as the month with the lowest mortality for Sweden, Canada and the United States. Although only two years of data were available for Japan, mortality was lowest in July. For Australia and New Zealand, average mortality was lowest in March and February (summer months in the southern hemisphere).
“Greater exposure to sunlight leads to increased synthesis of vitamin D, which may have beneficial effects for cardiovascular disease, renal failure, certain malignant diseases, autoimmune disorders and infections, including influenza,” they write.
