Are you on your smart device doing texting or surfing Facebook right now? If you are, take a break and check yourself for a moment. What posture are you using?
According to a study by Kennith K. Hansraj, an inappropriate posture can force 60 lbs of stress on your spine. Keeping that posture for long will have tremendous impact to your health, causing text neck (upper cross syndrome).
If you are felling tight neck or pain in your back, it is time to make some change.
