A joint makes up two opposing surfaces that touch each other and allow movement of those two bones.
An example is the elbow or knee joint or gliding joints such as the spinal joints. To make movement happen the muscles pull the joints in certain desired directions. Tendons attach the muscles to the bones and prevent damage to the muscle tissue directly from the joint movement. Ligaments connect tow bones together. They prevent a joint from having excessive movement. Such as the ACL of the knee.
Fluid within most joints lubricate the surface of the joint to prevent friction from occurring. Cartilage within the joint hydrates itself by synovial fluid; which occurs by a process called imbibition.
When the joint moves the fluid is forced into the joint to lubricate it and provide a nice fluid motion of the joint. Therefore no rubbing or chaffing occurs in the joint between the two bones.
In such as a spinal disc which is the cushion or shock absorption between two vertebrae of the spine, there are two parts. The ligament type of the outer portion and the inner portion which is more gelatinous like the jelly of the jelly-filled donut.
Both of these portions are primarily water-based. They rely on the process of previously mentions imbibition for nourishment of fluid and water. Therefore, is is imparative we move the spine to keep the spinal joints and all joints of the body hydrated to be healthy.
What happens if we don’t move? Then the joint doesn’t hydrate or lubricate and will become stiff and potentially achy. So don’t let the cold weather be the reason you are not moving. More so let the cold be the reason we get moving. Remember if you move you ward off the joint stiffness that can come with cold weather in the past.
