Why sleep matters -- the economic costs of insufficient sleep: A cross-country comparative analysis

“…While there is a large literature on the negative effects of insufficient sleep on individuals' health and productivity (see for example Giuntella et al, 2015;Hillman et al, 2006;Rosekind et al, 2010;Taheri, 2006), evidence about its potential wider economic costs is more scarce and comprehensive cross-country comparisons are lacking. The analysis presented in this chapter aims to bridge the gap by providing quantitative estimates of the costs relevant to five different OECD countries for which we have data available on the sleep duration in the population.…”

Broadband internet, digital temptations, and sleep

“…In many advanced countries, the share of individuals sleeping less than the recommended 7-9 hours of sleep is increasing (Hafner et al, 2016). The costs of sleep deprivation in terms of increased health care costs and decreased productivity are large (Gibson and Shrader, 2014;Hafner et al, 2016;Heissel and Norris, 2017;Jin et al, 2015;Giuntella and Mazzonna, 2016;Giuntella et al, 2017).…”

“…Motivated by the emergence of sleep deprivation as a public health epidemic, there has been a renewed interest in studying economic causes and consequences of insufficient sleep. A handful of recent studies exploit quasi-experiments and instrumental variable strategies to examine the effects of the lack of sleep on health (Jin et al, 2015;Giuntella and Mazzonna, 2016), academic achievement (Heissel and Norris, 2017;Hafner et al, 2017), cognitive performance (Giuntella et al, 2017), fatal crashes (Smith, 2016), and economic productivity (Gibson and Shrader, 2014). Despite the growing attention of doctors and medias on the potential negative effects of Internet and digital devices on sleep, to the best of our knowledge, there are no studies that examine the causal effect of the access to high-speed Internet on sleeping behavior.…”

Cognition and Alertness in Medical Students: Effects of a Single Night of Partial Sleep Deprivation

“…15,19,17 PSD, acutely and on a chronic basis, have been shown to have effects on cognition in many animal and human studies. 4,7,16,[20][21][22][23] Short periods of sleep restriction, say even an hour, after cognitive learning, can impair formation of memory. 24 In a study conducted among medical students elsewhere in northern India, 11 the P300 latency and amplitude were found to decrease significantly as compared to the test values at baseline.…”

“…Still, millions of people across the world are sleep-deprived. 1 Sleep deprivation has been observed to have a detrimental effect on the physical and mental health and abilities of an individual, [2][3][4] and it decreases attention span and performance. 5 This finally involves various social, financial, and health-related costs.…”
