Productivity and concentration increase when workers, employees and students have a good night sleep. Lack of sleep or poor sleep has short and long term consequences specially when we are talking about productivity in the workplace. The short term consequences range from drowsiness, lack of concentration, dossing off in the job, yawning to feeling sleepy; however, long term consequences are far more serious and sometimes more difficult to overcome: anxiety, irritability, depression, and memory loss among others. Individuals that suffer from insomnia may become less active and less able to concentrate as a result productivity goes down.
Employee’s lack of sleep or poor sleep costs companies about $2,500 per employee per year. Lack of sleep is responsible for employee absenteeism, errors, injuries and accidents in the workplace. Lack of sleep causes many on the road accidents and is considered a public safety hazard. Just like driving drunk slows reaction time so does sleep deprivation. Countless car accidents are due to lack of sleep specially in the younger population. Workers feeling sleepy during working hours have significantly more work related accidents and also have more sick days per accident. Absenteeism has a major effect in the economy.
Sleep deprivation impairs the cognitive processes such as attention, alertness, concentration, reasoning, and problem solving making it more difficult to learn and memorize. Sleep deprivation played a major role in some of the biggest disasters in recent history.
Research has shown that 30 min of napping time during the day can compensate for lack of sleep. A well rested individual is more productive, can concentrate better and is less prone to accidents and errors. Everyday more and more companies in conjunction with the human resources department are focusing on the employees health and wellness and providing not only information but also all the available means for the employees to catch up on sleep. Airports and universities are following along the same lines. Staying up all night to study or catching a plane may not be the best and most productive way.
We can safely say that sleep, productivity and concentration are linked.
