Could your smart phone be a burden to your spine?
What does a postural change mean in the spine? Are you de-evolving?
What does this have to do with me? Well... experiencing mood changes, decreased immunity (it takes me forever to beat a cold), digestive changes, sleep difficulties, heart rate function, etc...
There's a solution. Other than decreasing your own postural stress, check out upper cervical chiropractic care. It could save and change your life.
