 Our bodies require down-time in order to be most effective. We need moments where we can step away from the keyboard and allow ourselves to wind down and relax. Our minds are not designed for constant work, especially at the levels that computer programming requires. The sooner we realize we should step back and take breaks throughout the day to recharge ourselves the happier (and more productive) we will be.

 ## Taking a break
 
-Taking a break is more than just flipping to another application. I know my tendency for taking a break is to start checking email or head to one of the various chat programs I have in order to catch up on what's happened since I last took a break. But this is not really taking a break as it is trying ti multi-task at my desk. Real breaks require getting up from the computer. It doesn't have to be a large break;  taking a break can be as simple as standing up and walking from your workspace into another room or area. But you you need to stand up from your computer from time to time and get a "context switch" (where your mind can feel like it isn't in the same place as it was earlier).  It gives your mind the ability to completely switch out the context of the area you're in and allows it to focus on the new context and new input.

Context Switching lets your mind completely switch out and flush out the context of the area you're in. It allows your mind to focus on new context and new input.

-This can be tricky in an office situation where the expectation is that one must be at their desks in order to be productive. And there are only so many "bio-breaks" someone can take in such situations. How can you give yourself the context switch your mind needs in such situations?

 You might be able to achieve the same sort of context-switch by looking away from the computer display for a few moments. It's a good idea to look away from the screen every now-and-again to give your eyes a rest. Giving your mind a rest while you give your eyes a rest can give you the incentive to do both.
