If we compare the life of our ancestors and ours today we will find numerous unhealthy and unnatural habits we developed following "advancements of the system", the globalizing world. The way we work and communicate. Long periods of sitting are linked to multiple health problems like obesity, high blood sugar, depression, stress, metabolic syndrome and so on.  About 65% of the global population spends 7 – 10 hours or more sitting before a computer every day. Americans spend more than 50% of their waking hours sedentary. Physical inactivity is now blamed for 5 million deaths a year in the US only.

A human body is designed to move regularly, so siting for longer periods is highly detrimental to the health but the effects develop gradually, it will not happen in a day.
So, what happens when we are sitting:

Or muscular electrical activity drops down
Our calorie burning/ consumption drops 65% compared to walking
After 2 weeks of siting 6 hours /day we experience increase of fatty molecules, bed cholesterol, insulin resistance, blood sugar increases, oxygen consumption drops, it is harder to walk and climb stairs, weight risk increased.

After one year of sitting for 6 hours /day we have developed higher cholesterol, obesity and bone mass reduced for 1%/year. If we sit for 10 to 20 years it takes 7 years of our life span, increase risk of cancer and death by a hearth disorder.

Here it is:
