We all have that time of the day where the only thing we can think about is taking a nap. We could be one cup of coffee away from a caffeine-induced heart attack, and yet we still struggle to be productive.

Science says our circadian rhythms — our internal clocks — are responsible for this feeling. Every person’s sleep/wake cycle is different and depends largely on external factors that can, in fact, be controlled.

Many of these external factors also play a role in office productivity. For example, anyone who works with a computer knows how easy it is to go back and forth between social media and whatever they’re working on. Next thing you know, you’re an hour deep into what should have taken twenty minutes to finish, and you’re still not done.

Sometimes, all it takes is creating a schedule, rearranging the layout of the office, or simply prioritizing one project at a time. We created this infographic to show you 19 productivity tips to improve productivity that can be easily implemented.

How many of these science-based tips do you think you could use to improve productivity? These are not by any means the only solutions. The point is to get you thinking about what could be done differently to improve productivity, and that it doesn’t take monumental changes to implement them.

It often boils down to the little things, like painting the office a different color, turning your phone off, or throwing a plant on your desk, that helps people focus better. Maybe it’s simply giving yourself more breaks to either make that afternoon crash more manageable or taking breaks when you’re least productive and working when you’re naturally more energized.

Whatever the case may be, it’s imperative to improve productivity as much as possible. Too many businesses suffer from employees not working to their fullest potentials because of simple and avoidable reasons. The sooner these science-based productivity tips are implemented, the better.
