Study: Too Little or Too Much Sleep Affects Job Performance

You might think that skipping sleep to put in more hours at your place of employment can actually be rewarding in terms of your job performance. According to a new study, that is actually not true. Staying awake for a few more hours on the job may actually hurt your work attendance in the long run, according to the first nationally representative study to examine the link between sleep and work absences.

The study from the Finnish Institute of Occupational Health, published in the September issue of the journal Sleep, found that workers who slept less than five hours or more than 10 hours were more likely to stay home sick compared to those who got a normal and healthy seven to eight hours of sleep a night. They stayed home about 4.6 to 8.9 days more than regular sleepers.

“The consequences for the employees and individuals suffering from poor sleep are loss of well-being, health and work ability, and at organizational and societal level, the costs of poor sleep are high not only due to sickness absenteeism, but also sickness presenteeism (e.g. working sleep deprived),” concludes lead researcher Tea Lallukka, Ph.D. “It would be good to increase awareness of the importance of healthy sleep patterns, and aim to detect sleep disturbances at early phase to prevent them from becoming chronic.”
