According to an article in Live Science, the lack of sunlight-induced Vitamin D may have contributed to Mozart’s young demise. The authors of the study surmise that the Vitamin D deficiency could have made the composer more susceptible to a plethora of infections during the winter.
According to the authors of the study,
“Mozart did much of his composing at night, so would have slept during much of the day. At the latitude of Vienna, 48 degrees N, it is impossible to make vitamin D from solar ultraviolet-B irradiance for about 6 months of the year. Mozart died on December 5, 1791, two to three months into the vitamin D winter.”
The researchers include: D. William Grant, of the Sunlight, Nutrition and Health Research Center in San Francisco, and Stefan Pilz of the Medical University of Graz in Austria
