Effect too long in front of computer

6 Ways Sitting in Front of Your Computer All Day is Killing You (And What to Do About It)

Sitting is so much a part of our modern lifestyles that we often don’t realize how inactive we’ve become. For those of us who work online or in a work-at-home setting, sitting at a computer for hours on end working seems natural to our way of life. Add all the time you spend on the couch watching TV and in the car driving, and odds are you’re probably leading a sedentary lifestyle without even knowing it. And sitting for long periods of time is really, really bad for you.
Several studies show prolonged sitting ranks second after smoking as the world’s top risk factor for non-communicable diseases. Smoking edges out inactivity with 5.3 million deaths per year compared to 5 million deaths per year due to inactivity. "We just aren't really structured to be sitting for such long periods of time, and when we do that, our body just kind of goes into shutdown," observed Dr. Antronette Yancey (late UCLA public health professor) author of the book Instant Recess: Building a Fit Nation 10 Minutes at a Time.
Dr. Yancey had spent years working on developing programs to motivate people to get up and move. She emphasized the importance of healthy living through physical fitness and thought whoever invented sitting probably didn't have our best interests at heart. That's because sitting too much is dangerous. Here are six ways sitting is slowly killing you and you may not even notice it.

1.   Sitting all day causes body aches.

You don’t need an expert to tell you that sitting in front of the computer all day can give you body aches and pains, including a sore back and headache. Worse still, staring at the computer screen for prolonged spells of time leaves you prone to dry eyes. Dry eyes can lead to lower resolution of vision, severe damage to the eye ball and bad eye sight. But you already knew that, right?

2.   Sitting all day makes you fatter.

One report reveals that when we sit all day, “electrical activity in the muscles drops…leading to a cascade of harmful metabolic effects” that can cause you to gain weight. In other words, being a couch potato makes you fatter—no surprise there. What is surprising, though, is that even if you hit the gym or the jogging path daily, sitting all day is still bad for you. Working out is not a panacea—it cannot counteract hours of being sedentary.

3.   Sitting all day makes you dumber.

Another study conducted by German scientist Sabine Schaefer from the Max Plank Institute for Human Development reinforced anecdotal evidence that suggests sitting for long periods of time is not only bad for your body, but also for your mind. The study found that walking increases your resources of energy, which you can then invest in thinking and improve your working memory performance. Turns out the reverse also holds true. If you sit all day, it can lower your resources of energy, slow down your working memory performance and actually make you dumber. It’s a clear case of mental performance being superior when you are actually physically active.

4.   Sitting all day attracts chronic illnesses.

Prolonged sitting can also trigger unhealthy metabolic changes that lead to a myriad of chronic illnesses, including heart disease, hypertension, diabetes, stroke, kidney stones and certain types of cancer. In fact, the statistics show for every two hours spent sitting in front of the computer or television you raise your risk of lung cancer by 6%, of colon cancer by 8% and of endometrial cancer by 10%. Your risk of heart disease increases by up to 64% and you are 18% more likely to die from diabetes when you sit for more than 11 hours per day.

5.   Sitting all day triggers mood disorders.

You might think sitting in front of your computer the whole day makes you more productive, but in reality it lowers your productivity. That is because sitting for long hours per day causes fatigue and can trigger mood disorders like stress and depression. Evidently, a great deal of sitting not only messes up your physical and mental well-being, but also your emotional stability.

6.   Sitting all day lowers life expectancy.

Researchers Van der Ploeg and colleagues found that sitting too much increases risk of death by 40% regardless of any other activities one does. You shave off seven years of quality life just by sitting for 11 or more hours per day. Moreover, people who sit too long are more likely to die in the next three years than those who don't sit as long. This science-backed information should shock and convince all of us to change our lifestyles and combat the deadly "sitting disease."
