[Chinese and foreign toys and gift nets] If the child has unexplained finger or wrist pain, you may have to blame the electric toy .
American researchers point out that there is growing evidence that PDAs, cell phones, and other small video games are associated with stress injuries that can cause pain in the fingers and wrists of children.
The intensity of pain is proportional to time, and the longer you play, the easier it is to have pain in your fingers or wrists. But the survey also found that the younger the child, the easier it is to have joint pain, because their skeletal muscle system is not well developed and can not compensate for the need for excessive tendon and muscle activity.
Researchers suggest that parents should control the time spent on video games in their hands and not play for more than an hour a day. If your child is not over 7 years old, the best way is to not play at all. (Wang Sang)
