Chiropractic is based around the idea of removing imbalances (both structural and postural) in an effort to allow our body to heal itself. For this to happen, the network of nerves and signals from your brain down your spinal cord to the network of nerves must be allowed to flow freely without interruption. Chiropractors have the ability to remove potential interruptions or misalignments and allow the body to perform as it was meant to.
If you've ever been in a car accident, played a sport, fell down, or just bumped into something too hard, it's very possible that you are not functioning at your best due to a misalignment. While there are many potential mechanical or structural causes for misalignment, there are also chemical reasons. For instance, if you smoke or drink excessively or even just have a poor diet, the chemical issues in your body can eventually cause underlying conditions and disease to appear.
Allowing a chiropractor to get you back on track both chemically and structurally will return your body to the proper state it should be in to perform at its peak.
