人在夏季出汗多,训练时更是挥汗如雨。大量体液的丢失会引起血容量减少,这不仅使心跳加快,心慌胸闷,而且流向肌肉的血液也随之减少,脏器的运动就像在“干磨”,很容易受损。 相当多的人认为,缺水了应喝加氯化钠(食盐)的水,这其实是错误的。因为大量失水的血浆中,氯化钠的浓度已相对增高,呈高渗状态,如再补充盐,将促使钠离子增高,使失调的电解 People sweat more in the summer, when training is sweating. The loss of a large amount of body fluid will lead to decreased blood volume, which not only makes the heartbeat faster, palpitation and chest tightness, but also reduces the blood flow to the muscles. The movement of organs is like “dry grinding” and is easily damaged. A considerable number of people think that lack of water should drink sodium chloride (salt) water, this is actually wrong.
