Imagine being hanged four bowling ball weighing 4.5 kg at your neck.
According to recent research, that is exactly what we do when we looked down and focus on the smartphone.
Dr Ken Hansraj MD, Chief of Spine Surgery at New York Spine Surgery and Rehabilitation Medicine, said, we are at the starting point of a wave of back and neck problems caused by poor posture when using smartphones.
Hansraj initially interested in this issue after seeing more and more young people are consulted because of pain. In one case, a young man came up with a sore neck, back, and legs.
Surgery and then fix his legs, but Hasraj said the young man still feel the pain in his back and neck.
"At that time we know that he spent four hours a day playing games on the iPad," he said. "Look around you. Everyone looked down. "
Some use the term "text neck" to describe the situation.
Hansraj said, in a neutral position, the human head weighs about 4.5-5 kg.
If you bow your head as much as 15 degrees, you almost add the weight as much as three-fold, he said.
If as much as 30 degrees around 18 kg. A total of 45 degrees, nearly 23 kg, and 60 degrees, amounting to 27 kg.
People with smartphones typically spend between two to four hours a day with your head down to their devices, according to scientists. It is equal to between 700 to 1,400 hours per year with an additional pressure on the spine. Adolescents may spend more time, up to 5,000 hours per year, said Hansraj.
"Children today are not aware that they bow their heads around 45 to 50 degrees," he said.
To find out how large the scope of this problem, an estimated 60 percent of Americans own a smartphone.
According to research Hansraj, the best I can do is see a smartphone with a neutral spine position, which means keeping an ear on the shoulder with the shoulder pulled back.
And also, instead of down, you can also reduce the view to avoid pressure on the spine, he said.
"This is not a military exercise," he said. "Do not be in that position and continuously in that position. The more often you do it, the more muscles and ligaments strengthen awakened. "
Hansraj says, he was a big fan of technology, but he recommends smartphone users to be aware of where their heads.
The research was published in the National Library of Medicine and the VOA reported on Thursday (11/20/2014).
