Putting the clocks forward tonight might be expensive in terms of health, wealth and happiness, according to three separate pieces of research.
First, Laurence Jin and Nicolas Ziebarth have found “evidence of mild negative health effects when clocks are set forward one hour in spring”: in Germany, hospital admissions increase after the clocks go forward in the spring and fall when they go back in the autumn. This is consistent with the possibility that the extra hour’s sleep in the autumn improves our health whilst the loss thereof in the spring worsens it.
Secondly, there’s this (pdf):
Individuals in both the UK and Germany experience deteriorations in life satisfaction in the first week after the spring transition…We attribute the negative effect of the spring transition to the reduction in the time endowment and the process of adjusting to the disruption in circadian rhythms. The effects are particularly strong for individuals with young children in the household.
Thirdly, Mark Kamstra and colleagues have found that stock markets do badly around the time of daylight savings changes. In the UK, the spring DST weekend has seen the All-share index fall by an average of 0.4%, compared to a drop of less than 0.1% in ordinary weekends. This is consistent with the possibility that disruptions to our sleep patterns increase anxiety.
You might object that these findings suffer from p-value fetishism and publication bias. If you do, you might cite this as support: it finds no evidence that DST affects risk appetite or cognitive performance.
