How to Resolve Text Neck
Obviously the first recommendation would be to stop using cellphones or tablets for lengthy work related tasks such as emails, editing, or research.
Bringing the cellphone or wireless device to eye-level to read or increasing the text size and font to reduce leaning into the screen may also help.
Stand up or change positions every 15-20 minutes to reduce neck and shoulder muscle fatigue. This can include just looking up and stretching your neck. Just as looking down for long periods of time is all about repetitive stress to the cervical spine, looking up and stretching in the opposite direction may relieve the pressure on the neck/spine.
If All Else Fails
Prolonged texting with your neck craned forward, without taking a break, may cause irritated nerves and, over time, disc degeneration, headaches, and other problems. If you are in pain after using your cell phone or tablet for prolonged periods of time, then be sure to get in and see your chiropractor. Pain in the cervical spine or shoulders may be an indication that there is some form of cervical spine issue brought on by repetitive stress syndrome leading to spinal misalignments.
