Mental healthSunlightThis study examines the causal effects of sunlight exposure on suicide rates. Leveraging county-month-year data on solar insolation and suicide rates in the U.S. from 1979 to 2004, we provide first robust evidence that insufficient sunlight increases suicide rates. We also ...
The original assumption was that SCN neurones collectively drive or impose a 24h rhythm on physiology and behaviour. However, the discovery that isolated cells from almost any organ of the body produce clock genes/proteins in a circadian pattern led to a major shift in our understanding. We now...

Our current manuscript describes the aims and methods of a clustered randomized control trial (cRCT) on how sunlight-reflecting roof coatings, “cool roofs,” affect health, indoor climate, economic and behavioral outcomes in rural sub-Saharan Africa. This region currently suffers the largest disease...
