冷水浴可以提高神经系统的兴奋性,增强物质代谢和各器官的活动。全身皮肤接触冷水,在神经系统支配下皮肤血管急骤收缩,血管口径变细,大量血液流向内脏和深层组织,此时内脏血管扩张。稍停,皮肤血管又扩张,大量血液又从内脏流向体表。这样,在一次冷水浴过程中全身的血管都参加运动。所以经常进行冷水浴锻炼,一旦遇到气温骤冷的情况,神经系统会很快地调节皮肤血管收缩,体内产热过程加强,提高对寒冷刺激的耐受力。进行冷水浴的方式有擦身、冲洗、淋浴、洗澡和游泳等。冷水浴锻炼应从暖和季节(夏季)
Cold water bath can improve the excitability of the nervous system, enhance the metabolism and the activities of various organs. Whole body skin contact with cold water, under the control of the nervous system, rapid contraction of skin blood vessels, blood vessels become thinner, a large number of blood flow to the visceral and deep tissue, visceral vasodilation. Pause, skin blood vessels and expansion, a large number of blood flow from the viscera to the body surface. In this way, in a cold water bath during the whole body blood vessels participate in exercise. Therefore, regular cold water bath exercise, in the event of a sudden cooling temperature situation, the nervous system will quickly regulate skin vasoconstriction, heat production process to enhance and improve the tolerance of cold stimulation. There are ways to conduct cold water bath, washing, showering, bathing and swimming. Cold water bath exercise should be from the warm season (summer)
