Up to 25 % of the total circulation goes into the head. The vessels are in a narrow space between the neck vertebrae, throat and outer neck muscles (mainly a muscle called Sternocleidomastoides). All static poor postures of the head or the neck make muscles tense and reduce circulation in the main vessels. The main vein (Jugularis Interna) is actually leaning to Sternocleidomastoides. If the muscle is tense, the circulation slows down, the blood pressure in the brain increases and headache easily follows.
Good posture of the neck can be attained only when the whole back is in a good posture. Soft elbow pads close to the body help the shoulder area muscles to relax. The two-part saddle seat enables a good posture and prevents the aforementioned problems.
Using a high-quality saddle chair will increase the oxygen intake considerably. Stiffness and joint locks in the chest, ribs and the upper back decrease. This, combined with reduced muscle tensions and better posture, will make the whole breathing mechanism work better and allow the chest to expand fluently and the breathing to become deeper. Improved oxygen intake will increase the oxygen levels in the whole body and slow down the process of getting tired.
