Globally in 2000, excessive solar UVR exposure caused the loss of around 1.5 million DALYs (0.1% of the total global burden of disease), whereas a massive loss of 3.3 billion DALYs was attributed to a lack of UVR exposure and vitamin D deficiency. This is measured in disability-adjusted life years (DALYs), which you can think of as lost years of full health. To put these risks in perspective, we can consult a Global Burden of Disease report on solar ultraviolet radiation that contrasts the risks of excessive solar UVR exposure with a lack thereof, including vitamin D deficiency. Sunburns, heat strokes and skin damage are certainly no joke, on the other hand we need sunlight for some of the most basic functions in our body. When it comes to our health, the Sun often gets a bad rep for being very dangerous.
