There are more than six billion smartphone users worldwide and the time spent using them has steadily increased. Approximately two thirds of all owners in America spend at least one hour per day on their phones and about twenty hours per week texting, emailing and using social networks.
The most common postural disorder is forward neck posture. The head constitutes about 6% of one's total body weight and as we angle our heads downward to look at our phones, the effective weight on our neck increases providing a greater stress on the involved musculature.
There is a strong relationship between mobile device use and pain in the shoulders and neck, non-neutral neck posture is a well-known cause of this modality. Overuse of smartphones is not likely to decline, but we can offset the negative effect by continually strengthening our head and neck. No matter your purpose in training whether sport or recreation make this area an important part of an exercise regime to live a healthy lifestyle as we use today's technology.
