I don't want to alarm you but your workplace could be killing you.
Particularly your desk.
Recent studies have suggested that sedentary behaviours may play a role in reducing your lifespan.
Many of these studies demonise television but it's interesting to see a number of bloggers have drawn a parallel with sitting at a desk.
If you spend most of the rest of the day sitting — in your car, your office chair, on your sofa at home — you are putting yourself at increased risk of obesity, diabetes, heart disease, a variety of cancers and an early death. In other words, irrespective of whether you exercise vigorously, sitting for long periods is bad for you.
Sitting is one of the most passive things you can do. You burn more energy by chewing gum or fidgeting than you do sitting still in a chair. Compared to sitting, standing in one place is hard work. To stand, you have to tense your leg muscles, and engage the muscles of your back and shoulders; while standing, you often shift from leg to leg. All of this burns energy.
A study, published last year in the journal Circulation, looked at nearly 9,000 Australians and found that for each additional hour of television a person sat and watched per day, the risk of dying rose by 11 percent.
Another, based on data from the Australian Diabetes, Obesity and Lifestyle study, began in 1999 and asked more than 11,000 people aged over 25 about their weekly TV viewing.
The researchers then compared the viewing times with Australian mortality rates.
They found that in 2008 Australian adults watched 9.8 billion hours of TV and for every hour spent in front of the box their life expectancy dropped by 22 minutes.
Those who watched the most TV a day - six hours - lived 4.8 years less than those who watched none.
