Imagine carrying an 8-year-old around your neck
several hours per day. The human head weighs about a dozen pounds. As the
neck bends forward and down, the weight on the cervical spine begins
to increase.
That’s the burden that comes with staring at a smartphone —
the way millions do for hours every day, according to research published
by Kenneth Hansraj in the National Library of Medicine. Over time,
researchers say, this poor posture, sometimes called “text neck,” can lead
to early wear-and-tear on the spine, degeneration and even surgery.
Just look around you, everyone has their heads down. Smartphone
users spend an average of two to four hours per day hunched over, reading
e-mails, sending texts or checking social media sites. That’s 700 to 1,400
hours per year people are putting stress on their spines, according to the
research. And high-schoolers might be the worst. They could conceivably spend
an additional 5,000 hours in this position, Hansraj said.
“The problem is really profound in young people,” he said.
“With this excessive stress in the neck, we might start seeing young people
needing spine care. I would really like to see parents showing more guidance.”
Medical experts have been warning people for
years. Some say for every inch the head tilts forward, the
pressure on the spine doubles.
Tom DiAngelis, president of the American Physical
Therapy Association‘s Private Practice Section, said the effect is similar to bending a finger all the way back and holding it there
for about an hour.
“As you stretch the tissue for a long period of time, it
gets sore, it gets inflamed,” he said. It can also cause muscle strain, pinched
nerves, herniated disks and, over time, it can even remove the
neck’s natural curve.
Poor posture can cause other problems as well. Experts say
it can reduce lung capacity by as much as 30 percent. It has also been
linked to headaches and neurological issues, depression and heart disease.
“While it is nearly impossible to avoid the technologies
that cause these issues, individuals should make an effort to look at their
phones with a neutral spine and to avoid spending hours each day hunched over,”
according to the research.
Hansraj gave smartphone users tips to avoid pain:
- Look
down at your device with your eyes. No need to bend your neck.
- Exercise:
Move your head from left to right several times. Use your hands to provide
resistance and push your head against them, first forward and then
backward. Stand in a doorway with your arms extended and push your chest
forward to strengthen “the muscles of good posture”
Technology is highly necessary and essential, but your just have
to be cognizant of where your head is in space. Continue to enjoy your
smartphones and continue to enjoy this technology. Just make sure your head is
up!
