This is why your fascia is dehydrated
Unlike muscles, fascia is slimy and gel-like. It consists of a approximately 70% water. Dropping below 70%, fascia starts becoming dysfunctional and inhibits the way your entire body functions.
Dehydration (systematic or local) will impair fascia's function, leading to restricted movement, then to pain, and later injury.
Myofascia degenerates due to various causes. The main causes are circulatory failures due to trauma or reduced physical activity, disuse syndrome, overuse syndrome due to repetitive motion, and chronic poor posture. This causes the densification of the fascia because of the twisted collagen fibers, which harden the substrate because of dehydration. In addition, sustained muscle contractions, such as overuse syndrome, causes hyaluronic acid aggregation, which is a factor that reduces the sliding properties of the fascia.
