Short-Term Impacts of Solar Lanterns on Child Health: Experimental Evidence from Bangladesh

We implemented a 16-month randomised field experiment in unelectrified areas of Bangladesh to identify health impacts of solar lanterns among school-aged children. Our analysis of various health-related indicators – self-reporting, spirometers, and professional medical checkups – showed modest improvements in eye redness and irritation but no noticeable improvement in respiratory symptoms among treated students. Varying the number of solar products received within treatment households did not alter these results. This limited health benefit was not caused by nonutilisation of the products by treated children, spillover effects from treated to control students, or contamination resulting from unfavourable family cooking environments.
