4 Ways Technology Might Be Injuring You

Tablet Neck

Any hand-held mobile device can cause posture problems, but it's hard to hold a tablet in an ergonomically friendly way, says Dr Szeto. Most people hold theit tablet too low-i.e, resting on their laps, or propped against their thigh.

When you look down at your tablet screen, you're also transferring more pressure to your upper spine; when that happens, your neck muscles have to work overtime to support your head, upping the odds that you'll strain those muscles.

To fix this, when watching a video clip on your tablet, prop up your tablet on a table, keeping it at eye level; If you are typing, try to use the device in the same way you'd use a desktop computer. For example, use a keyboard and place the screen on your desk at eye level. For smaller devices, raise up the phone when texting to eye level so that your neck supports the weight your head at an upright position.

Computer Vision Syndrome

People who use a computer for more than two hours a day may develop computer vision syndrome (CVS).

CVS refers to a group of eye problems that results from prolonged computer use. Most commonly, people experience eyestrain, headache, blurred vision,, and dry eyes. Although temporary for most people, these condition can be very disturbing, especially if they occur every day.

CVS is caused  because of high visual demands of computer viewing. The eyes need to work harder,and are usually at closer distance to the computer screen as they are in other viewing situations.

Doctors recommend that people ward off CVS by placing the screen about 4 or 5 inches below eye level, and 20 to 28 inches away from the eyes. Anti-glare screens and proper lighting may be useful in reducing eye problems.

PlayStation palmar hidradenitis

This newly identified skin disorder named after PlayStation is caused by holding the console too tightly for a long period of time.

"PlayStation palmar hidradenitis" or PlayStation rash, was first diagnosed in a 12 year old girl in Switzerland. She had developed painful lesions in her palm and nowhere else on her body. After questioning, the doctors discovered that just before the lumps appeared, the girl had been playing video games on her PlayStation for several hours daily.

"The tight and continous grasping of the hand-grips, together with repeated pushing on he buttons produce minor but continuous trauma to the palm surface," Vincent Piguet and colleagues at University Hospitals and Medical School of Geneva reported in the British Journal of Dermatology in 2009.

TV Screens and Photosensitive Seizures

As virtually all gamers have likely repeatedly seen in on-screen warnings, a small percentage of people may experience seizure or blackout when watching certain light patterns on a TV screen, or in video games.

About 1 in 100 people have epilepsy. and 3 to 5% of people who have a photosensitive for of it. It's not known what causes epilepsy, but abnormal wiring of the brain, or imbalance in brain's signalling chemicals are thought to have a role.

There is no cure for most types of epilepsy. People who have photosensitive epilepsy should avoid any regular moving patterns or flickering lights that might trigger the condition.
