Sitting in front of a computer all day in the office (or even at home), without proper breaks or awareness, can lead to a number of problems.

If you're not careful, it could lead to:
• bad posture;
• back or neck problems;
• tense or stiff muscles;
• eye strain;
• sore fingers, wrists or hands, from clenching the mouse,
• mental or physical fatigue.

The best thing to do is to have regular breaks, look away from the computer every few minutes, and stretch. It's important to increase your awareness of how you feel while you are sitting at your desk so you can correct your posture or muscle tension.

Of course, sometimes it's hard to remember to do that when you're busy or stressed out.

Many Japanese companies organize group stretches to invigorate and destress their workers.

Here are some simple stretches you can do by yourself at work.

But if you need an exercise video to show you some simple stretching exercises you can do at work, here's one I made with my cousins. I'm the one in the blue sports jacket (doing my best David Suzuki impression).
