3. Dietary habits
This might be surprising to a few people, but did you know that certain foods can contribute to inflammation. When your body is inflamed it can result in added stress on your nerves in your back, which may already be stressed from other lifestyle choices. Typical “unhealthy” foods like fast food and junk food are loaded with fats and have a high glycemic index. These things cause inflammation and may just be what pushes you over the edge to suffer from back pain.
On the other side of things, foods containing Omega 3 fats and antioxidants actually work to reduce inflammation in your body. Examples of these foods are fish (especially salmon), walnuts, and blueberries.
So, if back pain seems to be a problem in your life and no amount of stretching exercises seems to help, consider that instead of trying to combat the problem with stretches you might just need to stop doing the things that cause back pain, to begin with.
