Do you spend long hours sitting in front of your computer every day? If you do, then beware the chair! You could very well sit your way to an early death!
Prolonged periods of sitting increases the risk of diabetes, heart disease, bowel cancer and mental fatigue. A recent study conducted by researchers at the Australian National University and Sydney University further discovered that there’s a direct link between hours of uninterrupted sitting and the likelihood of early death.

Why a Workout Doesn’t Offset Prolonged Sitting
Professor Emily Banks and Associate Professor David Dunstan followed 200,000 people aged 45 and over, in a span of 3 years and found that those who sat for 11 or more hours a day, had a 40% increased risk of early death compared to those who sat for less than 4 hours a day. Those who sat for 8 hours a day, were 15% more likely to die early.
In another study, scientists at the Pennington Biomedical Research Center in Louisiana analysed the lifestyles of more than 17,000 men and women for 13 years, and found that people who spent most of the day sitting are 54% more likely to die of heart attacks.
The bad news is that an hour at the gym before or after 11 hours of sitting does not cancel out the negative effects of sitting. But there’s good news – getting up and out of your chair every 20 minutes to simply stretch your legs and move for 2 minutes, DOES cancel out the health hazards of sitting!
The Rise of Stand-Up Desks at Work
If you think small things can’t do much damage or impact anything, then try falling asleep with a mosquito in the room. The same goes for your health. On the subject at hand, standing up from your desk and moving around every 20 – 30 minutes can do wonders to your circulation. You don’t have to do tuck jumps over your desk or other more strenuous activities to achieve the same result!
You still need your 30-60 minutes of exercise a day, but on top of that, you need to stand up regularly. Prolonged sitting disrupts metabolic functions resulting in lower levels of HDL (good cholesterol), higher levels of triglycerides and LDL (bad cholesterol), and reduced insulin sensitivity. After an hour of sitting, the production of enzymes that burn fat in the body declines by up to 90%!
In particular, scientists at the University of Missouri identified that the act of sitting shuts off the circulation of a fat-absorbing enzyme called lipoprotein lipase, contributing to the development of obesity. We need muscle contraction to regulate the chemical processes in our bodies, otherwise things stagnate and stall.
Interestingly, in the 19th and 20th centuries, office workers mostly stood while working. Sitting was what you did when you took a short break. Winston Churchill, Benjamin Franklin, Leonardo da Vinci and novelist Vladimir Nabokov all advocated standing to improve creativity and concentration. Well, it certainly worked for them and standing seemed like a good way to greatness!
Living a more healthy lifestyle is very popular these days, and a fitness program in many forms are gaining a regular following. In the digital age, most people spend their waking hours at work, sitting in front of a computer. And it’s because of this trend that stand up desks have become increasingly popular in the workplace. Models like the one shown below allow the user to sit, use a stool or to stand while working.
Don’t have time to go to the gym, hit the trail, or get on the treadmill gathering dust in one corner of your home? Then a stand up desk just might be the solution for you. You many not be moving a lot as you would in a workout routine, but it will certainly keep your body awake, and your circulation going! If you want to know more about the health hazards of sitting for long hours, then this 5-minute segment on the ABC TV program, Catalyst, will tell you about it. You can watch it here…
Choosing the Right Chair and Ergonomic Workspace
Choosing the right chair and setting up an ergonomic workspace can transform your comfort. It will reduce fatigue and protect your body over time. It will pay off in better focus and fewer aches.
Adjustable Seat Height
Your feet should rest flat on the floor. Your thighs need to be parallel to the ground. Raise or lower the seat so your knees sit at a 90-degree angle or just below hip level. This position eases pressure on your lower back. It also improves blood flow and reduces stiffness.
Proper Lumbar Support
Look for a chair with built-in lumbar support. It will hold the natural curve of your spine. If your chair lacks support, try a small cushion or a lumbar roll. It will fill the gap between your lower back and the chair. Good support means less fatigue and fewer aches throughout the day.
Desk and Monitor Alignment
Your desk height should let your forearms rest level with the floor. Your monitor must sit at eye level or just below. That way you’ll avoid tilting your head up or down. Keep the screen about an arm’s length away. It will cut down on eye strain and neck tension.
Keyboard and Mouse Positioning
Position the keyboard close enough so your elbows bend at about 90 degrees. Place the mouse right next to the keyboard. That way you’ll prevent overreaching. If you’re prone to wrist pain, try a padded wrist rest. It will help keep your wrists in a neutral position.
Armrests and Chair Movement
Choose armrests that adjust in height and width. They will support your arms while you type or rest. Your shoulders should stay relaxed. A chair with smooth casters will let you reach for items without twisting. It keeps your posture aligned and prevents strain.
Accessories for Added Comfort
Consider a footrest if your feet don’t reach the floor easily. A monitor stand or an adjustable arm can fine-tune screen placement. Use an anti-fatigue mat under a standing desk to ease pressure on your feet. Proper lighting and a glare filter can protect your eyes. These simple extras can make a big difference.
Clutter-Free Workspace
Keep essential items within arm’s reach to prevent twisting or bending. Use a document holder next to the monitor if you work with paper. A tidy desk reduces distractions. It also supports a clear mind and better posture. Remove items you don’t use often.
Practical Tips to Break Up Sitting Throughout the Day
