Beijing time July 28th news, according to foreign media reports, experts warned that a tablet computer for more than 30 minutes a child may suffer in future life Chronic neck and back pain. Studies have shown that bending down in front of an electronic device in childhood may pave the way for bad habits, and these bad habits can cause a musculoskeletal problem when a child grows up. Stephanie - Cassidy, a bioengineer in Melbourne and a professional therapist, says that a child keeps a fixed position for up to 30 minutes and then moves.
experts warn that a child who plays tablet computer for more than 30 minutes may suffer from chronic neck and back pain in the future.
studies have shown that bending down in front of an electronic device in childhood may pave the way for bad habits, and these bad habits can cause a musculoskeletal problem when a child grows up.
however, researchers at Curtin University in Australia have found that many families allow children to play tablet computers for an hour or more. More than 40% of the parents surveyed admitted that they used electronic devices to ensure that children remained calm and happy for a long time.
postdoctoral researcher Pete Cohen South will present these preliminary results at the International Ergonomics Association meeting held in Melbourne in August. The scientist said the study is expected to reveal the appropriate level of electronic devices for children less than 5 years old. He said: "these behaviors in their early life may lead to musculoskeletal problems in their later life."
guidelines in some countries suggest that children aged 2 to 5 see screens (including TV screens) for up to one hour, and suggest that children under 2 are not able to use electronic devices. But Curtin University scientists studied 159 children and found that 1/4 children spent more than an hour watching TV every day in a week, and watching TV time increased by almost half an hour every weekend. The children surveyed were 5 or even younger, with 30 children under two years old. 60% of children spend more than one hour using tablet computers or mobile phones in a week. Nearly 10% of children spend more than one hour playing tablet computers on weekends.
Cassidy said she acknowledged that her daughter also used tablets, apple music players and laptops, but encouraged her to stay in good posture and pay more attention to activities. The scientist pointed out: "if she uses these electronic devices on the bed or sofa, I will say," use the cushion to support you. You can only play for 30 minutes at a time, then you have to stand up and move. If the child starts to say that the neck and back pain symptoms, it shows that the body can not adapt to their posture.
British charity Tablets for Schools found that nearly 70% primary and secondary schools in this country now use tablet computers. The latest research has come to the surface. Scientists say there is no clear evidence that students use tablet computers to improve their academic performance.
another study conducted by the British Trust Fund for reading and writing shows that 1/4 secondary school students describe themselves as "addicts" on the Internet. About 2/3 students go to bed with a computer device or smart phone, use social media or watch videos.
the discovery of the British Telecommunications Authority in early 2014 showed that about 70% of 5 to 15 year olds use tablet computers at home. As early as June, clinical psychologists warned parents could not allow children without school to use cell phones and tablets because it would damage their attention in the classroom.
