Not taking your eyes off your phone may damage your spine

Our cell phones and tablets have transformed the way we deal with our bodies - not for the better.

Looking at your device is like having a 27-pound weight on your neck, according to Dr. Kenneth K. Hansraj, head of spine surgery at the New York Spine Surgery & Rehabilitation Medicine. from New York, in free translation). This is like holding an eight year old around your neck while you are standing reading your messages.

Hansraj developed the computer model above. Not surprisingly, moving your head forward and having the same amount of force in your neck and spine is not good for your health. The bad news is that the average human being spends 2 to 4 hours a day in this position.

Since our heads are quite heavy - weighing up to 5.5 kg, or - when we are often looking down for long periods, we are increasing the gravitational pull on them. And, as it turns out, this force is very large.

The study notes that having a good posture is having your ears aligned with your shoulders and shoulder blades behind you. This reduces stress on the body and decreases cortisol. Poor posture, on the other hand, accentuates the spine and can lead to early wear and perhaps surgical intervention.

Some solutions to correct posture: Hold the phone directly in front of you, instead of bending your head down; place your tablet at a 30 degree angle when typing or tapping (the angle protects your wrists) or more perpendicularly if it's read-only and straighten your neck back to correct your posture.
