If you're on a mobile device, your arms are bent by your side and your back hunch is even more profound.
The position you're in is probably causing you pain, whether you're aware of it yet or not. Don't worry, physical therapists have a diagnosis for the headaches, neck cricks and achy shoulders. They call it "Text Neck."
"Text Neck is not just a texting problem," said Dr. Dean Fishman. "Text neck is a gaming problem. Text neck is an e-mailing problem."
Fishman originally coined the term in 2008
while examining a 17-year-old patient. The teen came in complaining of headaches and neck pain. As Fishman was trying to explain to the patient's mother exactly what the problem was, he glanced over and saw her posture.
The teen was sitting in a chair, hunched over her smartphone, texting away.
"I knew I had something," Fishman said.
A recent study
published in Surgical Technology International's 25th edition says texting may be hurting your back. Conducted by New York spine surgeon Kenneth Hansraj, the study found that bending your head to look at your mobile device held in your hands can put up to 60 pounds of pressure on your neck.
Hansraj's study includes illustrations of what happens when mobile users bend their heads at at 15, 30, 45 and 90 degrees to look at their devices. He advises users be cognizant of their bodies.
"We recommend that people should continue to enjoy their smart devices, but that they pay specific attention to where their head is in space," Hansraj told the Huffington Post.
"You want to be careful that your head is straight up with you're using a smart device."
The average human head weighs 10 pounds in a neutral position -- when your ears are over your shoulders. For every inch you tilt your head forward, the pressure on your spine doubles. So if you're looking at a smartphone in your lap, your neck is holding up what feels like 20 or 30 pounds.
