Using a regression discontinuity design combined with a differences-in-differences approach, we find that the Spring DST causes a significant decline in life satisfaction. By inducing a reallocation of time, the transition into DST deteriorates sleep and increases time stress, which in turn affects physical and emotional health. After performing a simple cost-benefit analysis, we find evidence suggestive that ending DST would exert a positive effect on welfare, namely the wellbeing costs associated with DST exceed its benefits.}, keywords={Daylight Saving Time;wellbeing;health;sleep;time stress}, }
