Health Warning at your desk to work can be injurious to health.

Blog on Health warnings at workplace - Sakra World Hospital

Can we imagine a life without computers? Electronic s and computers have percolated into our life at an alarming pace and magnitude. This has occurred at a scale to make me wonder if typing skills in my children are at par, if not more significant than handwriting skills. Needless to say many of us spend hours in form of a computer at work and top it up with a few more hours in front of Mr. Computer at home. As a pain physician involved in helping desperate patients with persistent pain, I see an epidemic of occupational hazards.

“@your Desk to work can be injurious to health” is not a tagline I would associate with undertaking a routine relaxing job on a posh comfy expensive chair. The sound of it resonates with health hazards of smoking. The sheer volume of time spend in front of Mr. Computer in its many forms , small and big, is making a generation regress back to the dark ages …really?

Musculoskeletal disorders due to sustained unhygienic postures is creating epidemic of health problems centered mostly around the neck, shoulders, arms and upper back. You could argue, I don’t think our ancestors with similar postures suffered with health problems. Well…… probably not since they were not ashamed and frequently to ambulate on all fours (limbs).

We have to take charge and modify our workplace, accommodate our schedules to reduce the impact of our activities on our health. I draw inspiration from the “Microsoft Healthy computing Guide” to suggest modifications in our work / leisure related Mr. Computer activities to ensure we continue to benefit with the marvels of the rapidly developing / evolving world we live in. We should aspire to be comfortable and productive with Mr. Computer.

This guide is designed for anybody spending more than 2 hours with Mr. Computer. This is relevant and probably equally important even if you are fortunate enough to have had no aches and pain in top half of your body. The commonly issues are occasional discomfort in hands, arms, shoulders, neck, upper back and even headaches. Any persistent aches, tingling numbness, burning / shooting pains in your arms / fingers warrant an assessment by a qualified doctor. The suggestions / advice below are generic and applicable across a wide spectrum of people. However, I recommend an individual detailed assessment, if you continue to experience ongoing discomfort. If you have access to an occupational therapist / physician professional guidance to arrange tour workstation will be beneficial.

Tip 1: Position Yourself

Avoid sustained postures for extended periods of time with any activity to avoid discomfort, fatigue and pain. Workstation redesign is essential to avoid unhygienic and awkward sustained postures. The workstation should promote and maintain a comfortable relaxed posture.

To support your back, try the following:

Use a chair that supports your lower back preventing arching with convexity pointing behind you. (See detail 1).
Adjust your work surface and chair height to assume a comfortable and natural body posture (see detail 2).

To promote comfortable leg postures, try the following:

Clear away items from beneath your desk to allow comfortable leg positioning and movement.
The height of seating should ensure a rested foot on the floor and horizontal thighs on the seat.

Tip 2 - For a comfortable shoulder and arm postures:

Place your keyboard and mouse or trackball at about elbow level. Your upper arms should fall relaxed at your sides (see detail 3).
Centre your keyboard in front of you located close to it (see detail 4).
Place frequently used items comfortably within arm's reach (see detail 5).

Tip 3 - For comfortable wrist and finger postures:

Keep your wrists straight while typing or mouse navigation. Avoid bending your wrists up, down or to the sides.

Tip 4 - For Comfortable neck posture:

The top of the screen should be positioned at your eye level. If using bifocal glasses, it may be useful to lower the screen.
Centre your monitor or document holder in front of you depending on what you refer to most often.
Consider using a document holder to position your documents near eye level.

Tip 5 - To reduce eye strain:
Position your monitor an arm's length away from you when seated comfortably in front of it.
Place monitor away from sources of glare.
Maintain a clean screen and glasses if you wear some.
Optimize the monitor's brightness and contrast, along with a good font size.

Tip 6 – Avoid repetitive strain injuries – Be gentle to yourself

Repeated monotonous work maneuvers, or sustained pressure / impact on body parts can result in body injuries. Common examples include pressing the keys while typing, clicking the mouse buttons, holding your mouse or cradling the phone and resting your wrists on the edge of your desk. You can dampen the effect of these.
Be gentle to yourself - Type with relaxed hands and fingers ensuring a light touch that is sufficient to activate the keyboard keys, clicking a mouse button, when using a joystick or other gaming controller.
Try maintaining a floating wrist and hands (see detail 7). The palm rest, if provided, should only be used during breaks from typing.
Relax your arms and hands when you are not typing or using your mouse. Avoid resting hands on furniture edges.
Adjust your chair so the seat does not press into the back of your knees (see detail 8).

Tip 7 - Take Breaks

In a supercharged workplace taking breaks may not be feasible. You can certainly take a break from repetitive task and resort to change in activity. Take a walk out supervising juniors. Stretch yourself during a telephonic conversation. These breaks can be tailored to you and your work place.

Tip 8 – Balance between work and play to limit strain on same body part:

Organize your diary to have a good admixture of activities that do not strain the same body part for extended periods of time.
Utilize the different Mr. Computer input devices to accomplish the same task. E.g. scrolling with move wheel versus arrow keys.
Understand feature in Mr. Computer to work efficiently. E.g. Ctrl C instead of mouse right click copy.
Eat a balanced diet and get adequate rest.
Regular exercise for overall fitness and to improve the strength and flexibility of your body.
Manage stress of and home by good scheduling and time management.

Tip 9 – A healthy body and mind

A healthy peaceful mind ensures productivity and higher tolerance for repetitive tasks. A tensed, stressed mind tightens / strains the muscles in your upper back and neck limiting the tolerance of MR. Computer related activities.

Maintain good health by:

Eat a balanced diet and get adequate rest.
Regular exercise for overall fitness and to improve the strength and flexibility of your body.
Manage stress of and home by good scheduling and time management.

To conclude:

I wish you a healthy, productive, efficient, happy relationship with Mr, Computer who is likely to encroach into all domains of our lives. We wish you a happy computing experience, and don’t forget to look after yourself.
