Transcript for Do You Have 'Text Neck'?
morning, what they call text neck. A condition they say caused by spending hours and hours looking down at our phones or gadgets putting strain on our necks and new cases are cropping up around the country. Dr. Besser here in just a second but first ABC's Mara schiavocampo. Reporter: Your technology can literally be a pain in your neck. All day every day, people are looking down at iPads, laptops and video games. And one doctor says it could be causing an epidemic of neck pain. So "Gma" decided to look into what some doctors are calling text neck. Many, many people are using their necks in a poor posture or poor position doing many things. Reporter: Over time he says, text neck can lead to early spine degeneration, even surgery. Just ask Todd Snyder whose neck pain became unbearable. I realized that I was on mobile devices for one to two hours a night even more checking my e-mails, doing notes on the computer, texting friends, responding back to colleagues. Reporter: Dr. Hans diagnosed him with text neck and said Todd like many of his patients has lost the natural curvature of his spine pulling it out of alignment. The spine is straighter, losing that belly shape. Reporter: And for teen Matthew David texting three to four hours every day exacerbated an old football injury. When I like started bending my head down like I could feel the tension in my neck a lot. As a parent it's pretty heartbreaking because it's an indication of where we are in the times. Reporter: But some doctors we reached out to say text neck is just a fancy term for pain people have been experiencing for years. It's really nothing more than an overuse type of injury just like you would see with any other kind of repetitive activity. Reporter: Other doctors tell us additional studies need to be done to learn more about the issue. In the meantime, Dr. Hansra says, pay attention to your headan D neck. For "Good morning America," Mara schiavocampo, ABC news, new York. So those are the details on text neck. You say it's a real thing. It is. You know, it is a type of overuse injury but if you think about how people are acting now. This is what we're doing. We're using text messaging and so there are a number of Simms you'll see with this. You can see neck pain or stiffness. Can you have headaches, and can you pain in your shoulder, your back or down your arms. All of those can be a symptom. What do you do? Well, the interesting thing here what happens as you put your head forward. So the average human head weighs about ten to 12 pounds and as -- with good posture that weigh weight is going down your spine directly on to your neck but as you move your head forward, the direction of the force changes anticipate your neck experiences enormous amounts of weight. Let me show you. So as your head goes forward 15 degrees it's equivalent of having three gallons of milk, the weight of that ex-erred on your neck. On your spine. On your spine. Right on your neck. As you go down to 30 degrees, it's equivalent of a five-gallon drum of water. That is crazy. 45 degrees, take a look at this. It's equivalent of having two tires -- No. On your neck. That's incredible. Is this a good idea? What do you think about this? Look at this. 60 degrees, Roman, how much do you weigh? 60 pounds. 60 pounds. Hey, Roman, can you lay off the French fry, dude? It would be on Dan's shoulders, it would be on Dan's neck that that would be -- What do you do to prevent this? I'll put Roman down. That's what I'm going to do. Oh, good. So I mean the prevention -- first thing if you can back off on how much you're texting. The other is when you're texting instead of looking down if you can hold your phone up. Yeah, like this. Like that. You're not putting those forces there. But then in addition to that, there are things can you do. Exercises to increase the flexibility in your neck and some of the strength. So, you know, take a look at this first video. This is a rotational video here. Rotational exercise so you're turing your head to the side and with your hand exerting some force stretching those muscles there and you do that for a couple of seconds to both sides. The second one is a head tilt. And with this you're tilling your head to the side trying to get your ear down to your shoulder. That is stretching those muscles on the other side, hold for a couple seconds and do it over to the other side. And then the third one is a shoulder roll so you pinch your shoulders back and then you're in a sense doing a rolling motion with your shoulders backwards and forwards. Those are all going to improve your posture, help keep your neck over your head and in addition I love yoga for this. But those arms he has -- Exactly. I was going to say. Minds think alike. I've got Besser neck right now because you're like 6'5". It's always a challenge. Always a challenge. I'll use those reverse tips after this segment.
