Harms of stiff bones
1, easy to get hurt
When you fall, if your body is soft and good, you will be able to react quickly without too much damage to your body; however, stiffness may cause more serious injuries or even fractures.
2. Body pain
Sclerosis of the body leads to slow blood circulation and coldness of the body. Touching those painful parts is usually cold and hard.
3, fear of cold
About 40% of the body's heat is produced by muscles. When muscles decline, harden, and blood circulation deteriorates, the amount of heat produced decreases, leading to a lower body temperature.
4, often fatigue
When the muscles harden, the capillaries distributed in them will also harden, resulting in the blood can not flow properly.
An important role of blood circulation is to deliver nutrients and oxygen, and to recycle waste substances in the body that lead to fatigue and tiredness. When blood circulation functions poorly, the body is prone to feel fatigued.
5. Weight gain
The energy and fat consumed by the body need to be burned through muscle movement. Once the muscles are stiff and unable to move sufficiently, it will lead to a decline in metabolic function and fat will not be burned and accumulate.
6, rough skin
When the muscles or blood vessels harden, it will also affect the blood circulation of the skin, facial dryness, pigmentation, dullness, wrinkles, flaccidity and other problems.
