Daylight Saving Time and incidence of myocardial infarction: Evidence from a regression discontinuity design


  • Toro, Weily
  • Tigre, Robson
  • Sampaio, Breno


Limited evidence suggests that Daylight Saving Time (DST) shifts have a substantial influence on the risk of acute myocardial infarction (AMI). Previous literature, however, lack proper identification necessary to vouch for causal interpretation. We exploit Daylight Saving Time shift using non-parametric regression discontinuity techniques to provide indisputable evidence that this abrupt disturbance does affect incidence of AMI.
