You are doing research on people's sleeping habits. You found two articles. Japanese women sleep less than 7 hours each day. For some people, that might be enough, but for many others, it could cause some problems in the sleep a little more than eight hours and a half on average, which seems It looks like people in my Country are doing fine. Both men and women Around the globe, the amount of sleep that people get every night has long run. Japanese people, especially women, would need more sleep. 50 第4問 (配点 16) o 第2回 実戦問題 51 Average time per day spent sleeping in selected OECD countries plus China, as of 2016 How Long Do Peopleinthe World Sleep? by Kim 9:0 9:00 9:30 8:52 8:38 8:33 8:26 July, 2018 9:00 8:30 been steadily decreasing since the 1970s.

No one around me sleeps more than nine hours a day, except for 6:00 China USA Australia France Japan small children. How can they sleep so long? One possible explanation could be that the ratio of people working in the primaryindustry in China is very high (27.0%). Those of the other countries are between 1.4% (USA) and Opinion on “How Long Do People in the World Sleep?" 3.4% (Japan), according to the International Labour Organization (ILO) statistics. People doing physical labor might need more sleep. by Yoshimi Ito August, 2018 As Kim mentioned, Japan has to deal with the problem of short sleep. Japan shows a marked contrast to China. Japanese men sleep one hour and eight minutes shorter than Chinese men and Japanese women sleep However, that is not all. As the graph shows, women in our country sleep bour and 28 minutes shorter thanChinese women, It may not be a big sixteen minutes less than men. We should address the issue of gender gap, deal if all Japanese women slept more than seven hours and 36 minutes. Dt this “seven hours and 36 minutes 1S the average, which means a lot of too. One thing I would like to point out here is that Japanese men spend much less time on housework than women. In 2011, women spent three hours and 45 minutes a day on housework (care for household members plus routine housework) while men spent just 31 minutes, according to OECD data. It is common to see wives who work full-time do most of the housework as well. The sad truth is that there are still many men who quite appropriate to me. seriously believe that housework mustbe done by women. We might have LO start by making them change this kind of mentality. n my opinion, two things are certain. First, many Japanese are not deal with these problems right away. 無2回
