Looking down at your phone for too long
It’s no secret that the majority of us have smartphones and that we frequently look down at them… even when walking around in public. Forget the fact that you could run into people or objects due to distraction, your neck is really getting it here. While there really isn’t an ideally better way to look at your phone short holding it right in front of your face (which no one ever does) there are a few little things that can help.
Strengthen your lower back and core with some exercise. This will help you with posture and balance. Also, maintaining a healthy weight will help you avoid back problems.
