Health Tips of Frequent Computer Users

A few things to remember while sitting before a computer

Keep your wrist unsupported while typing. Do not use gel pads as wrist-rests.

Sit with your back supported against the chair’s backrest, and with thighs sloping down slightly so that your hips are higher than your knees.

If your boss won’t do it for you, invest in an ergonomically sound office chair: ideally, one with a head-rest and lumbar support. The seat-height, and angle between seat and chair back should be adjustable.

If you feel a Computer Related Injury (CRI) coming, address it early. Learn preventive stretches from a CRI expert.

Make sure a light source or window is not directly reflecting off your screen – for instance, by building a simple shade out of file folders.

Blink regularly or use a solution to keep your eyes lubricated; running a humidifier in an air-conditioned office can also help avoid dry-eye symptoms.

It is better to have your head angled down to your screen than up – having to look up at a screen reduces blink-rates.

Follow the 20-20-20 rule: every 20 minutes, focus on an object 20 feet away for 20 seconds.

Laptops are an inherently un-ergonomic devices as the screen and the keyboard are attached. When using a laptop at home or office, use an external keyboard and mouse, and a laptop stand to prop the screen to eye level.

Ideally your keyboard and laptop should be placed just above the level of your lap, with your elbow at an angle of 100 degrees.

Consult an expert before using any medication targeting CRIs.

Q 1: You are participating in a race. You overtake the second person. What position are you in?

Answer: If you answered that you are second to last then you are wrong again. Tell me, how can you overtake the LAST Person?

Q 3: Tricky arithmetic…try this one…do not use paper and pencil or a calculator.

Take 1,000 and add 40 to it. Now add another 1,000. Now add 30. Add another 1,000. Now add 20. Now add another 1,000. Now add 10. What is the total?

5000?

Answer: You are wrong again…the answer is 4100…if you don’t believe, check it with a calculator.
