Proper Setup Benefits Health, Productivity

Whether you’re setting up a new office, or just want to improve on your old workspace, office setup can be a daunting task.
 
Where do you start? What do you need, and what should you look for? When done right, creating an organized office space can make all the difference. Reduce stress, increase your productivity and be kind to your body with a fresh start for your office.
 
When buying furniture, account for ergonomics, and how all the pieces of the office will work together. Function should take precedence over style or price, though finding items that fit all three shouldn’t be too difficult.
 
Minnesota office organization expert Sue Rasmussen emphasizes that there are three key pieces to most people’s office layouts, a good desk, a good chair and a filing cabinet.
 
Make sure your desk is large enough but also that everything you need is within reach to prevent straining. Halifax professional organizer Colette Robicheau suggests an L-shaped desk for extra workspace.
 
Chiropractic rehabilitation specialist Dr. John Papa of New Hamburg adds that the desk should be at elbow height so that arms are supported while keyboarding. Position the computer monitor so that the upper-third is at eye-level for easy viewing, Papa advises.
 
Most importantly, be aware of your posture and be sure not to slouch, distribute weight unevenly in your chair, or roll your head too far forward or to the side. And don’t cradle the phone between your head and shoulder. Use a headset or the speaker phone feature.
 
As we spend increasing amounts on computers, tablets and smart phones for both work and pleasure, the risks are becoming apparent. “Sitting - it’ll kill you,” is the tagline around his lab, says Dr. Jack Callahan, who holds the Canada Research Chair in Spine Biomechanics and Injury Prevention at the University of Waterloo.
 
Callahan has been studying chronic pain related to office work since 1996. The research shows that those who spend the majority of their time sitting have a higher rate of injury than those who perform mixed tasks, he explains.
 
Known as Sedentary Disease, too much sitting is also associated with an increased risk of heart disease, obesity, high blood pressure, diabetes and premature death.
 
If you’re sitting for more than two hours a day, Callahan recommends investing in a good quality office chair. “Adjustability is really important,” says Callahan. The back rest and arm rests should be adjustable as well as the height of the seat, he explains.
 
What’s known as the 90-90-90 position, feet flat on the floor and elbows at a 90 degree angle, is a good starting position but it’s also important to adjust your position several times throughout the day.
 
For himself, Callahan has invested in a chair that allows him to alter his position between sitting and standing. These chairs have been shown to reduce pain and discomfort, he explains. For every hour of work the best ratio seems to be about 45 minutes sitting and 15 minutes of standing, he says.
 
And if you’re using a laptop computer or a tablet it’s just as important to maintain good posture. You shouldn’t be bent over, craning your neck to type on it, explains Callahan.
 
For laptops he recommends a second screen or a second keyboard (the cheaper option) so you can maintain good posture. For a tablet he recommends having a stand and keyboard if you’re going to use the tablet for inputting content as opposed to just consuming content.
 
Even with the proper furniture and equipment, it’s important to take breaks, says Papa. Repeating a simple stretching routine throughout the day can prevent years of chronic pain.
 
Simply changing your work habits is more than worth the pain and stress it can save you in the long-term, he points out.
 
With the right office equipment, the right setup, being aware of your posture, and taking frequent breaks, you can increase productivity and reduce the risk of chronic back pain.

Sitting Down On The Job






Does your job find you sitting most of the day?
 
While sitting can seem restful, keep in mind that staying in any one position for long periods of time can cause strain and injury to your muscles, joints, tendons and ligaments. Sustained sitting can take a toll on your neck and lower back – steady compression on the spinal discs hinders their nutrition and can contribute to premature degeneration.
 
So, if you have to sit at work, what can you do to stay pain-free? Help take the load off your back with these tips:
 

Take frequent breaks

 
First, ensure that you take regular breaks from sitting. Get up, take a short walk outside or around the office, and stretch.
 

Posture perfect

 
Next, pay attention to your posture. Sitting incorrectly puts strain on your lower back, decreases blood flow to your working muscles and accelerates fatigue. Practise “active sitting” with your feet flat on the ground in front of you, your back straight, your shoulders squared and your chin parallel with the floor. This posture will strengthen the “core” muscles of your abdomen, sides and back to reduce the strain on other areas. The stronger your core muscles, the easier it will be to maintain good posture.
 

Choose a good office chair

 
What’s most important in preventing injury and strain is to be able to easily vary your sitting positions throughout the day. An investment in a good office chair can help a lot. The right chair for you should:
  • Be easily adjustable to suit your size
  • Adapt to support your spine in various working positions
  • Have a backrest that supports your lower back
  • Have armrests, if they are appropriate to your work
  • Have a front edge that curves downward to promote proper posture

Stability balls

 
One recent trend is to use a stability ball at the office. While a ball is a great tool to help you tone your abs at home or at the gym, it should not replace a good chair at your work station. If you do bring the ball to work:
  • Use the ball only for short periods
  • Use your abdominal, back and side muscles to maintain straight posture
  • Stop when your muscles feel tired
 
Sitting on a ball instead of a chair can actually increase the pressure on your back, especially if your core muscles aren’t strong. So, sitting a long time on the ball may lead to greater discomfort in your lower back. Do not use a ball if you have osteoporosis, balance or low back problems.
 
 
Remember, stability balls are not for everyone; consult a chiropractor if you have any pre-existing injury or health problems that could impact your balance or stability.

Top 5 Tips For Selecting An Office Chair

Ontario Chiropractic Association (OCA)

When shopping for the best ergonomic office chair, getting a chair that fits your unique needs should be the top priority. Not every chair labeled “ergonomic” has all the adjustment features necessary to truly be ergonomic. Here are the top 5 things you need to consider to help you make a better selection.
 
 
1.  Seat pan comfort and shape
When you sit in the chair the seat pan should be at least one inch wider than your hips and thighs on either side. The seat pan should not be too long for your legs otherwise it will either catch you behind the knees or it will prevent you from leaning fully back against the lumbar support. Most ergonomic chairs have a seat pan with a waterfall front that prevents the seat from catching you behind the knees. The seat pan should also be contoured to allow even weight distribution and it should be comfortable to sit on.
 
2.  Think adjustable
Always ensure that your chair is pneumatically adjustable so that you can adjust seat pan height while you are sitting on the chair.
 
You should be able to adjust the height of the seat pan so that the front of your knees is level or slightly below level and your feet are firmly on the ground. In most cases there should be no need for you to use a footrest. The mechanism to adjust seat height should be easy to reach and operate when you are seated.
 
3.  Lumbar support is key
Many chairs have cushioned lumbar supports that can be adjusted up and down and forwards and backwards to best fit your shape. If the chair will be used by multiple users then this level of adjustment may be required. However if you are the primary user of the chair then a fixed lumbar support may be acceptable, if it feels comfortable.
 
4.  Don’t forget about the hips
A chair that doesn’t provide enough hip room can make you sit too far forwards on the seat pan, which doesn’t provide so that you will not have enough thigh support.
 
5.  Have a long-term strategy
Think about how the chair will feel after 60 or 120 minutes. Low-density foam seat pans can become permanently deformed after long term use which can affect cushioned support leading to discomfort, imbalance and hip and back fatigue.
 
And one bonus tip!
 
6.  Chair covers 101
There is a whole range of upholstery materials available, each of which has benefits and concerns. Vinyl and vinyl-like coverings are easy to clean and spill resistant, but they don’t breathe and if the chair begins to heat up under the thighs uncomfortable amounts of moisture can accumulate. Cloth upholstery is the most common covering, but this is less resistant to spills and more difficult to clean. A cloth covered seat pan can also become warm and moisture laden, and cloth covered foam seat pans can be a significant source of dust mite allergen. When selecting your chair covering think about cleaning and maintenance issues and plan appropriately.
