【題目】When we do the same movements with our bodies over and over again, we overuse some muscles. And that overuse can lead to strain (勞損) and injury. Sometimes those problems can come from doing sports. But there is another cause for muscle problems: hand-held technology devices.

Staring down at your phone or tablet for long periods of time puts great tension on your neck. Experts say this posture puts strain on the entire upper body. Muscle strain linked to hand-held technology has become such a common condition that it now has a name: tech neck.

Common symptoms of tech neck are neck pain, loss of feeling in your hands and fingers, headaches -- both mild and severe -- and poor posture. In the worst cases of tech neck, you can lose the strength in your hands and fingers.

You can take simple steps to improve tech neck. Take breaks from using your technology. Stand up and stretch your legs often. Also, give your eyes a break by closing them throughout the day. Do neck exercises. Experts at the website Spine Universe recommend these three neck stretches.

Chin (下巴) Stretch

Move your chin towards your chest. Hold for 5 seconds. The stretch should feel comfortable from your neck to the base of your skull. Repeat 10 times.

Side Lean (傾斜)

Lean your head to the right. Bring your ear close to the shoulder. Hold for 20 seconds. Bring your head back to center, and then tilt it to the left, again holding for 20 seconds. Repeat 3-5 times on each side.

Side-to-Side Head Turning

Turn your chin towards your right shoulder. Hold for 20 seconds. Bring your head back to the center, and then turn it to the left, again holding for 20 seconds. Repeat 3-5 times on each side.

And if your tech neck symptoms get worse, see a health care professional.
