Shut-Eye Deficit: OECD Survey Reveals Japan Most Lacking in SleepLifestyle
Around half of Japanese people in their forties get less than six hours of sleep per night. A 2017 national health and nutrition survey conducted by the Ministry of Health, Labor, and Welfare, measured the daily average sleep (based on the previous one-month period) for men and women in their twenties and over. Of those who reported that they either did not feel properly rested or had no real sleep at all, the highest percentage of respondents was people in their forties at 30.9%. This was followed by 28.4% in their fifties and 27.6% in their thirties. Due to long working hours and commuting times, the reality is that many of those in the prime of life are suffering from sleep deprivation.
For men in their forties, 11.3% answered that they got less than five hours sleep and 37.2% responded that they got more than five hours sleep, but less than six, adding up to 48.5%. For women in this age group, 10.6% responded they slept less than five hours and 41.8% said more than five but less than six. This totaled more than half with 52.4%. People in their fifties also had high ratios with 44.9% for men and 51.6% for women.
Overall, the highest ratios for sleep by hours were 35.0% of men and 33.4% of women answering that they slept more than six hours but less than seven. People getting the longest sleep were those in their seventies and over, with only 21.7% of men and 31.1% of women responding that they slept less than six hours.
In 2009, the ratio of people who answered that they either could not get enough proper rest or could get no sleep at all totaled 18.4%. Of those people, 27.9% were men and women in their forties and 19.9% were those in their fifties. However, in 2017, these ratios had risen by 2-8 points.
OECD statistics via the Gender Data Portal 2019 shows that daily average sleep is 528 minutes in the United States, 508 minutes in Britain, 513 minutes in France, 516 minutes in Spain, and 542 minutes in China. Many other countries also average more than 500 minutes. Compared to this, Japan has the shortest average with 442 minutes and South Korea also scores low with 471 minutes.
