September 25, 2018

Tokyo- Nearly half of Japanese may be suffering from insomnia, a survey by bedding manufacturer Nishikawa Sangyo Co. showed Tuesday.

In the survey conducted over the Internet in July on 10,000 people aged 18-79, 49.3 pct were suspected of having insomnia, based on international standards for time needed for falling asleep, the quality of sleep and daytime drowsiness.

Respondents who were somewhat suspected of having sleeping problems accounted for 18.2 pct and those who were thought to be safe from the illness made up 32.5 pct.

Of respondents in their 20s, 61.1 pct were suspected of suffering from insomnia, the highest proportion among all age groups. The percentage was the second highest, at 58.5 pct, for people in their 30s.

Regarding the quality of sleep, 31.8 pct of all respondents said they are satisfied, while nearly 70 pct are not. The proportion of satisfied sleepers was the lowest for respondents in their 40s, at 23.6 pct, and the second lowest, at 25.2 pct, for those in their 30s.

"The survey results showed that people in their most productive years and those raising children are not getting sufficient sleep," said an official of Nishikawa Sangyo.

The percentage of respondents who are getting enough sleep stood as low as 26.1 pct for people in their 40s and 28.1 pct for those in their 30s. Jiji Press
