The so-called stretching is a kind of lifting the elbow of the arm up over the chest. However, why does such a simple action have such a magical effect? As we all know, stretching can make the chest organs of human body squeeze the heart and lungs, which is beneficial to the sufficiency of the heart and make more oxygen supply to various tissues and organs. At the same time, due to the activities of upper limbs and upper body, more oxygenated blood can be supplied to the brain, which makes people feel awake and comfortable immediately.
Human anatomy and physiology tell us that although the weight of the human brain only accounts for 1/50 of the whole body weight, the oxygen consumption of the brain accounts for 1/4 of the whole body oxygen consumption. Due to factors such as walking upright, human beings are more likely to lack adequate blood and oxygen supply in the upper body and brain. In addition, a lot of mental work can easily lead to cerebral ischemia, hypoxia symptoms, dizziness, numbness in the legs, backache, and reduced work efficiency. Therefore, it is absolutely beneficial to stretch your limbs regularly to restore fatigue. Yu Shengguang, 1 10, a long-lived old man, is tired from work. He always has to do a set of "White Tiger Boxing" or stretch a few times before continuing his work. This is the fitness philosophy that he realized all his life. Please stretch more after sedentary.
