Computer users and office workers who spend long hours sitting in one position at their desk run a higher risk of developing deep vein thrombosis (formation of a blood clot in a deep vein, most commonly in the legs).
Doctors warn that the clots can travel to the heart, lungs or brain, causing chest pain, breathlessness or possible death from a heart attack or stroke.
While it is often recommended that office workers take break, get up and walk around - there are some simple yoga exercises that you perform without leaving the desk.
Yoga Instructor Marcia Langenberg provides short Yoga training videos for download (Yoga @ Desk) that you can watch and perform inside the walls of your cubicle. These exercise videos are especially designed for people who work at their desks for most part of the day:
Part 1: Introducing the Exercises (9:40 minutes)
Part 2: Linking the Exercises to Your Breath (12:17 minutes)
Part 3a: Varying the Exercises (9:57 minutes)
Part 3b: Varying the Exercises (8:40 minutes)
