Most children have ever heard their parents yell “sit up straight!” or “don’t hang your head !” when they eat dinner. Nowadays, it is also heard around another activity — video games. Ten-year-old Owaish admits it takes him three to four hours a day to play games on his tablet computer. In addition, he plays for about two hours on the smart phone every day. As a result, he started suffering a serious pain in the neck around June or July. What’s worse the pain has spread to the hand and back gradually, which makes his mother Mehzabin become concerned.

The doctors note the number of young children with the chronic pain(慢性病) in their necks, arms and shoulders is on the increase sharp in recent years . They are not aging, they haven’t had an accident, the blood reports are fine, their X-rays are fine, and their MRIs are fine. Facts have proved that the pain is from the poor posture(姿势) while they are playing video games on smart phones or other electronic devices. 19-year –old student Nida feels pain in the finger which holds the weight of her smart phone most of the day. Nida almost uses her smart phone 24/7, which means 24 hours a day, seven days a week, or all the time.

Health experts predict there will be not only physical（身体的）but mental(精神的) problems resulting from the overuse of electronic devices. They encourage people to often take breaks and exercise from using computers, smart phones or other devices. Stand up! Stretch(伸展) the legs, back, shoulders and arms in all the possible directions. That’s the most effective way and maybe the key to solving the problem completely. After all, the medication doesn’t help sometimes.
