You are always glued to yours smartphone? Be careful, in the long run this can lead you to blame (or worsen) back and neck problems. This is revealed by an American research.
According to New York Spine Surgery and Rehabilitation Medicine scholars, led by Kenneth Hansraj, stay always said to look at your mobile or tablet can be equivalent for the back to carry a 7-8 year old child.
Dr. Hansraj estimated the weight on the spine based on the different inclinations that the neck can take (from 15 to 60 degrees) when the person is busy looking at their mobile phone, estimating that an inclination of 15 degrees involves a load equal to 12 kg, 30 degrees corresponds to 18 kg; 45 degrees at 22kg and 60 degrees at 27 kg.
Research has noted that on average, people spend 2 to 4 hours looking at their mobile devices using incorrect posture. This concretely translates, over the course of a year, into a total of hours ranging from 730 to 1460, far too much time during which people virtually carry this heavy burden and which in the long run can cause real injuries to the spine. vertebral.
To avoid running into these problems, experts advise (to those who just cannot detach a little from their smartphone) at least to send sms, emails and surf the internet while staying careful to maintain the right posture. He explained what Dr. Hansraj himself is:
"Just try to look at the phone keeping your back in a neutral and not tense position, with your ears aligned with your shoulders and your shoulder blades retracted."
The study was published in the Surgical Technology International journal.
