“Sleep deprivation is doing more harm in Japan than just making people grumpy and unhealthy. It is also holding back the world’s third-largest economy,” creating an economic drag of nearly $140 billion or roughly 2.9% of GDP. This is a much larger GDP slice than Canada (1.35%), Germany (1.56%), the UK (1.86%) or the U.S. (2.28%) lose to sleep deprivation. Moreover, periodic surveys by the Ministry of Health, Labour and Welfare, show the number of people averaging less than 6 hours of sleep per night has risen by about 10% since 2007 to nearly 40% of Japan’s population.

“Not only does poor sleep dent productivity, it also causes impulsivity and poor decision-making, according to sleep researchers. Sleep deprivation has been indicated as a cause in 7.8 per cent of all the US Air Force’s Class A accidents, defined as costing $1m or more). Sleep-deprived US workers cost their employers $63bn in lost productivity, according to a 2011 Harvard Medical School study.”
