Mynavi Corporation (Headquarters: Chiyoda-ku, Tokyo, Representative Director, President and Executive Officer: Shunsuke Awai), which operates the comprehensive job information site "Mynavi Tenshoku" (https://tenshoku.mynavi.jp/), announced the results of its "Survey on Sleep and Work" conducted among 600 full-time employees in their 20s to 50s. This is the first time this survey has been conducted.
【TOPICS】
◆ About 1 in 4 full-time employees sleep less than 6 hours. The ideal average sleep time is about 7 hours, showing a gap of about 1 hour from reality [Figures 1, 2]
◆ The causes of sleep deprivation are "burden of working hours and commuting time" and "stress from work and human relationships". Those in their 20s show a higher tendency for "anxiety about the future, vague mental unwellness, and overthinking" compared to other age groups [Figures 3, 4, 5]
◆ The most common impact of sleep deprivation on work is "lack of motivation for work and taking time to get started". Sleep deprivation may be leading to a vicious cycle at work [Figure 6]
◆ About 60% recognize that sleep is important for "preventing mistakes", "achieving results at work", and "smooth human relationships". The higher the annual income, the higher the awareness of the connection between sleep and work [Figure 7]
◆ About 1 in 4 full-time employees sleep less than 6 hours. The ideal average sleep time is about 7 hours, showing a gap of about 1 hour from reality.
While adults are recommended to get 6 or more hours of sleep*, when asking full-time employees in their 20s to 50s about their actual sleep time, the average was 6 hours and 14 minutes. 26.9% answered "less than 6 hours (total)", indicating that about 1 in 4 people have a shorter sleep time than recommended. The ideal average sleep time was 7 hours and 13 minutes, creating a gap of about 1 hour between the ideal and reality. Furthermore, the most common ideal sleep time was "8 hours to less than 9 hours (48.0%)". When asked about the frequency of sleep deprivation, "2 to 4 days or more a week (38.8%)" was the most common, followed by "5 to 7 days a week (31.7%)". While the average sleep time is over 6 hours, a certain number of people still feel sleep-deprived. [Figures 1, 2] *Ministry of Health, Labour and Welfare "Sleep Guide for Health Promotion 2023"

◆ The causes of sleep deprivation are "burden of working hours and commuting time" and "stress from work and human relationships". Those in their 20s show a higher tendency for "anxiety about the future, vague mental unwellness, and overthinking" compared to other age groups.
Regarding the causes of lack of sleep, "burden of working hours/commuting time (38.1%)" and "stress from work/human relationships (38.1%)" were the most common overall. By age group, those in their 30s showed a particularly high rate for "burden of working hours/commuting time (44.3%)". Additionally, in their 20s, "stress from work/human relationships (43.2%)" and "anxiety about the future/vague mental unwellness/overthinking (42.4%)" tended to be higher compared to other generations. Looking at current working hours, people with a higher frequency of sleep deprivation tend to have longer working hours, with an average difference of about 50 minutes compared to the overall average.

◆ The most common impact of sleep deprivation on work is "lack of motivation for work and taking time to get started". Sleep deprivation may be leading to a vicious cycle at work.
Regarding the impact of sleep deprivation on work, "lacking motivation and taking time to get started (22.8%)" was the most frequent, followed by "becoming distracted and making careless mistakes (typos, forgetting things, etc.) (21.8%)" and "being struck by intense drowsiness or dozing off during meetings or at the desk (21.8%)". By age, the 50s demographic showed a particularly high tendency for "being struck by intense drowsiness or dozing off during meetings or at the desk (27.2%)". Sleep deprivation increases mistakes and breaks concentration, which can prolong working hours and make troubles more likely to occur, suggesting it may lead to a vicious cycle. [Figure 6]

◆ About 60% recognize that sleep is important for "preventing mistakes", "achieving results at work", and "smooth human relationships". The higher the annual income, the higher the awareness of the connection between sleep and work.
When asked how they think sleep affects their work, "I think sleep is important so I don't cause trouble to others through work mistakes (62.5%)" was the highest, followed by "I think sleep is important to achieve results at work (61.0%)", "I think a workplace with many sleep-deprived people negatively impacts the atmosphere (59.2%)", and "I think sleep is important for smooth human relationships (58.8%)". It was found that more than half of the respondents consider sleep important for progressing smoothly at work, producing results, and maintaining a good workplace atmosphere and relationships. Looking by annual income, the percentage for many items tends to be higher as income increases, suggesting that awareness of the connection between sleep and work varies by income level. [Figure 7]
