Tilting your head multiplies the apparent weight that your spine needs to support and this pressure isn’t doing you any good.

According to the study, tilting your head 15 degrees forward would increase the amount of stress to 27 pounds. Tilt 30 degrees and it becomes 40 pounds. Tilt 45 degrees and it becomes 49 pounds and if you move even further and tilt your head 60 degrees, it becomes 60 pounds. The worse news is a lot of people tilt their head at 60 degrees in order to focus on their smartphones.

But it’s not the end for Facebook and text lovers, as a little adjustment can make a big difference. Our expert recommends always having proper posture, and that means to your shoulder blades and your shoulders aligned and your back in neutral position.

This might put a little stress on your arms for lifting your smartphone higher but hey that’s the reason these gadgets are becoming lighter.
