The economic loss that excessive daytime sleepiness causes businesses is estimated at approximately ¥19.8 trillion per year, and roughly 1 in 10 employed people are said to experience severe daytime sleepiness even when they get sufficient sleep at night.
Nomura Research Institute (NRI) reported, based on the content of a media forum held on 26 August, that daytime sleepiness could be a cause of economic loss. The annual economic loss attributable to daytime sleepiness is approximately ¥19.8 trillion, with productivity losses among the EDS group, who are aware of their sleepiness, identified as the primary factor.
Approximately 1 in 3 employed people fall into the EDS group, and roughly 30% of them are classified as getting “sufficient” sleep. This suggests that sleepiness is not caused solely by insufficient sleep duration.
The EDS group experiences marked disruption to day-to-day work, including losing awareness during meetings, slower work and an increase in data-entry errors. The findings also suggest a risk of affecting critical decisions and safety checks. Companies are said to be expected to treat daytime sleepiness as a business risk, provide ongoing support and improve the workplace environment.
