Ergonomics and Work Breaks – Helpful or not?

I recently read an interesting article regarding taking effective breaks at work.  This article stated that the most productive 10% of their surveyed population took a regular work break of 17 minutes out of every 52 minutes.  The authors surmised that this improvement in the productivity of the individuals who took work breaks was due to the fact that as people, we get bored easily, and as our boredom grows, our attention to our work similarly decreases, resulting in lower productivity over time, unless we take a work break.

I used to study classical piano performance at university, and when one practices for 5 plus hours a day, things can become monotonous and unproductive unless you have a plan.  In addition, the musical works one is learning (which are also many), are long and intricate and require a clear mind and direction.  My piano professor used to make me divvy up my piano practicing day into 30 minute blocks and then divide the musical works that I needed to learn and master across these blocks.  Then, strictly adhering to this schedule, I was required to practice for 25 minutes and then stop and take a 5 minute work break before continuing with the next 30 minute block and piece of work.

I used to think that I would never get anything done.  However, surprisingly, a lot of work was covered over time.  Following this method of taking work breaks, I used to succeed in learning a lot of difficult musical work, faster and better than I would’ve done, had I never followed his model and taken my work breaks.

This is pivotal, since many musicians (and office workers) tend to think that they need to get started with their work and then drive forwards until they hit that sweet spot of concentration and continue until they hit the wall of physical and mental fatigue.  We all know, however, that once you’ve hit that wall, your productivity takes a serious dive.

The problem with this approach to work is that you end up exhausting yourself so that after 2 or 3 hours, your brain is a rag and anything you do afterwards is unproductive and sometimes counterproductive.  When you’re tired and depleted like this, the other downside in addition to reduced productivity is that you also become prone to making mistakes.  This is because your mind is no longer clear and sharp, rather it is clouded by fatigue.

There are other studies that have been undertaken to determine the benefits of work breaks for office workers.  These studies looked at the optimal work break schedule as well as the effects of taking a work break on the participants.

Due to different study models, an optimum work break schedule is hard to pin point, however, some researchers recommend taking a 5 minute work break every half an hour, or 2 x 15 minute work breaks in your day, or 4 x 5 minute work breaks over the course of your day.  What was clear from the research was that it was very detrimental to your health and your productivity if you worked for 4 hours or more without taking any work break.

These studies also found, however, that taking work breaks also helped to improve productivity, reduce fatigue and  reduce phycial aches and pains.

 

Food for thought next time you feel that you’re far too busy to take a work break because of a deadline that you have to meet?  Perhaps, you might find it easier and faster to meet that deadline if you plan a few work breaks into your day?
