Sitting can be a nice break from a busy day. However, considering that many of us spend their entire workday at a desk, one has to wonder how prolonged sitting can affect your body and your health. This video examines the science behind sitting down, from the number of hours recommended for sitting to different improper body postures involved. It also looks at the effect of sitting on your spinal cord, lungs, brain and physiology. Finally, the video presents safe preventative methods and techniques that anyone should use if they are sitting for extended periods. This video was made by Demystifying Medicine students Abdullah Shahzad, Dalia Nasser, Oana Danielle and Yousif Eliya.
