白開水止渴 有學理根據Water under the Zhike have academic

白開水止渴 有學理根據 【陳惠惠】口渴嗎？喝白開水才能解渴，有甜味或會冒泡泡的飲料愈喝愈渴。 「當然是白開水最能解渴。」林口長庚醫院臨床毒物科主任林杰樑解釋，當血液裡鈉離子濃度增加、滲透壓升高，人就會感覺到口渴，這時候，可讓滲透壓快速下降的方法就是喝白開水。所以，白開水止渴，可是有學理根據的。 至於其他飲料，林杰樑舉例，果汁、可樂都屬於「高滲透壓」飲料，口渴時喝，根本是「飲鴆止渴」。許多年輕人運動後喜歡來一罐運動飲料，補充電解質，也有人把牛奶當水喝，以為「一兼二顧」，解渴又補鈣，林杰樑說，運動飲料視濃度不同，從「高滲透壓」到「等滲透壓」都有可能，牛奶則是「等滲透壓」，解渴效果都不如白開水。 他說，像嚴重腸胃炎時電解質大量流失，才需要喝運動飲料補充電解質，一般狀況下流汗，水分流失比電解質多，這時候該補充的是水分，並非電解質，可別補錯了。 2008-09-05 Water under the Zhike have academic [Chen Huihui - thirsty? » Drink boiled water to quench their thirst, or sweet bubble will take more to drink more thirsty to drink. "Of course, is the most water can quench their thirst." Linkou Chang Gung Memorial Hospital Clinical Toxicology Branch main Renlin Jie Liang explained that when the blood concentration of sodium ions, osmotic pressure increased, people will feel thirsty, this time, will allow rapid decline in the osmotic pressure Way is to drink boiled water. Therefore, water Zhike, but a theoretical basis. As for other beverages, Liang Lin Jie, for example, fruit juice, cola are all "high osmotic pressure," drink, drink when thirsty, is "Yinzhenzhike." Many young people to exercise like a can of sports drinks, added electrolytes, and some of the water to drink milk when that "one of the two LAB", thirst and calcium, said Liang Lin Jie, depending on the concentration of different sports drinks, from "high permeability Pressure "to" osmotic pressure, such as "may, milk is" osmotic pressure "and quench their thirst results are not as water. He said that, like severe gastroenteritis at the huge loss of electrolytes, only need to drink sports drinks added electrolyte, the general state of sweating, loss of moisture more than the electrolyte, which is added when the water is not electrolyte, can not fill wrong. 2008-09-05 For more information, see World Journal News ePaper
