“…1 In addition, several studies indicate that the transition in and out of DST causes disruptions in the circadian rhythm and adversely affects the duration and quality of sleep (Lahti et al, 2006;Kantermann et al, 2007), which in turn may have unintended negative side effects in various (economic) dimensions other than energy saving. These negative short term effects range from lower general well-being (Kountouris and Remoundou, 2014) and life satisfaction (Kuehnle and Wunder, 2016), decreases in stock market returns (Kamstra et al, 2000) and students' performance (Gaski and Sagarin, 2011) to higher risk of work injuries (Barnes and Wagner, 2009;Lahti et al, 2011), acute myocardial infarction (Janszky and Ljung, 2008;Jiddou et al, 2013;Toro et al, 2015), suicides (Berk et al, 2008) and fatal road accidents (Varughese and Allen, 2001;Sullivan and Flannagan, 2002;Sood and Ghosh, 2007;Smith, 2016). 2 While this literature provides evidence in favour of abolishing the yearly ritual of changing the clocks twice, at least from a short term perspective, it is less clear for which time regime -DST or standard winter time -a society eventually should opt for.…”
