Fascia is a sheet of connective tissue covering or binding together body structures, and is very widespread yet likely the least understood network of the human body.Fascia is made up primarily of densely packed collagen fibers that create a full body that wrap and divide every one of our muscles, bones, nerves, blood vessels and organs.
There are various kinds of fascia. They are classified according to their distinct layers, their functions and their anatomical location: superficial fascia, deep (or muscle) fascia, and visceral (or parietal) fascia. Superficial fascia is a fascial sheet lying directly beneath the skin. Deep (or muscle) fascia surrounds our muscles and muscle groups. Visceral fascia surrounds our organs and keeps them suspended in the correct place within our body cavities.
Chronic stress can cause the fibers to thicken in an attempt to protect the underlying muscles. Poor posture, repetitive movements, and lack of flexibility pull the fascia into knots.These tight knots or connective adhesions which act as trigger points can cause pain. A variety of treatments including myofascial release and stretching are used to treat this condition, which can be painful. You can also help keep your fascia healthy by stretching, staying hydrated and reducing stress.
