The T-Shirt is ideal for wearing if one has pain/complaints in the shoulder region, or the neck and back.
To achieve optimal effects, skin contact is important, so if you have problems with your back then it should not hang too loosely. If you have lumbar back problems then it is better to use the back brace. An alternative is to sleep in the T-shirt as that provides good skin contact. If it’s the shoulders you have problems with then the T-shirt may be looser fitting as the T-shirt always has direct contact with the shoulders.
The Tee shirt is made up of fibers of polyester and polypropylene (some of the products are mixed with cotton fibers) with a ceramic powder fused into the fibers. The ceramic gives the fabric its unique property, which reflects body heat in the form of infrared heat radiation. This helps to prevent injuries, relieves muscle tension, assists with range of motion, expedites recovery and increases circulation.
