多饮水能否稀释血液?这个问题是肯定的。多饮水对健康老人可预防高粘血症,对心腑血管病患者而言则更不容忽视。饮水也是有学问的。饮料、浓茶、盐水,甚至人造纯净水、太空水等对于人体都不是理想的液体。因为一些饮料虽然口感较好,也有一定的营养,但含有较多的糖、糖精和色素,对胃粘膜有一定刺激,也加重了肾脏的负担,摄入过多还会转化成脂肪,引起肥胖甚至糖尿病。从石油及煤焦油中提取的合成色素,还是潜在的致癌因素。盐水可使细胞脱水,而影响体液平衡;冰水刺激胃肠粘膜血管收缩,影响消化液分泌,进而影响消化功能;纯净水、太空水中不含微量元素,只能促进人体排泄废物。 Can drinking more water dilute the blood? This question is affirmative. Drinking more water on the health of the elderly can prevent hyperviscosity, the heart of patients with vascular disease is even more should not be ignored. Drinking water is also learned. Drinks, tea, salt water, and even artificial pure water, space water and other liquids are not ideal for the human body. Because some beverages taste good, but also a certain amount of nutrition, but contains more sugar, saccharin and pigment, a certain stimulation of the gastric mucosa, but also increased the burden on the kidneys, excessive intake will be converted into fat, causing obesity Even diabetes. Synthetic pigments extracted from petroleum and coal tar are also potential carcinogenic factors. Saline can dehydrate cells, and affect body fluid balance; ice water to stimulate gastrointestinal mucosal vasoconstriction, affecting the digestive juice secretion, thus affecting the digestive function; pure water, space water does not contain trace elements, can only promote human excretion of waste.
