狂飲水，點解會死?

Question

o係幾耐時間?
飲幾多會死?

《：___jess*``桐___ =]》, 你所說的是否指:
「High water or salt gradients between an animal's environment and its tissues will increase the rate of exchange between the two.」

「 In a hypo­osmotic environment the body fluids are hyperosmotic and are consequently faced with continual flooding of water and a leaching of of their salts. 」

Answer 1

我覺得點解飲都太多水會死...
可能係因為我地體內會自動條整osmotic balance(水份既平行)
咁當你係咁飲水既時候,你身體就會有好多水...
而當然d水有d會被absorb..多餘個d就會排出體外..
個係過份多既時候,身體既水份會多過我地細胞入面既水份好多...
細胞係可以allow water diffusion 既...所以水會係higher concentration diffuse 去lower concentration.. 咁所以就會有可能由身體到diffuse 入d cells 到啦(因為細胞唔係有好多水)
咁當太多水入cells, 咁佢地個membrane 會付荷唔到..就會burst. 咁就會對我地好危險```

係自己上堂學既...唔知係咪好o岩ga...
希望幫到dd 啦

坦白說，我不是醫生，我不知道飲幾多水和狂飲水後幾耐時間會死。我只是知道醫生和營養師專家說過正常人每日要飲八杯水。我相信若果我們不飲超過八杯水是不會死的，請放心飲水吧！不過我聽醫生講不要在很短時間飲太多水因為會引起胃漲例如連續飲八杯水。我相信最好是分開時段去飲水，例如早上飲三杯，下午飲三杯、晚上飲兩杯（最好分開來飲，每次飲一杯）。最好睡覺前一小時不要飲水以免半夜要去洗手間，影響睡眠。我相信飲水是對我們身體是最有益，只要跟上面的指引便可以放心飲水，是不會死的。
