Too much of good thing?- drinking water

4 07 2012

According to UPI news , a young woman in California died shortly after entering drinking contest.

It is a tragic event that should not have happened.

Water drinking has become a fad in health industry. It is being promoted as a necessary step in maintaining a good health. Water bottling industry has prospered so fast in the last few years. Is there any medical study done to support it? I don’t think so, because it is bound to fail.

As we drink in water, immediately, our blood volume increase. The concentration of all components in the blood is diluted. Notes that we have about 4-5 liters of blood in the entire body. If we drink one liter of water, our blood will be diluted 1/4 to 1/5 in less than half an hour. The concentration of every components of blood, like electrolytes, blood cells all would be diluted. We will be very sick if we don’t get rid of it within this period of time.

This is what happened to this poor woman.

(Update: This was first written in 2007. There was a new study about drinking lots of water in reputable medical journal recently, 2011 which totally debunked the myth of benefit of drinking too much water.  Jan 2012)

的確很嚇人 我今早還要某人用喝水來減肥
也是錯誤的觀念嗎
運動飲料聽說也不能多喝
怎樣是很多呢 真是麻煩

Hi, Shoshay,

The rule of thumb is moderation. I doubt”喝水來減肥” could be effective.
Running to bathroom for sure.

Hi, 女兒.
Surprise!!

注意,注意
喝很多水但尿頻繁且很少很少又沒流汗
請立刻去看醫生
你的腎臟有問題了

還有不喝水或喝不夠水對身體的排洩循環有Negative的影響
早上起床後,先如廁,
然後喝杯約300-500cc的溫水
對身體健康絕對有好處

水 有 進 就 要 有 出 排 汗 ﹐ 排 尿 都 行 。
多 喝 不 排 的人 少 ﹐ 因 為 水 積 在 身 體 內 ﹐ 是 不 舒 服 的 。 一 般 人 一 定 會 找 醫 生 的 。
無 緣 無 故 渴 ﹐ 而 大 喝 大 排 尿 ﹐ 那 就 要 注 意 ﹐ 可 能 是 糖 尿 病 。

一直在想這位只喝了四瓶(32 once)就出事的案件
也許這位小姐的腎臟有潛伏性的毛病
才會如此不耐喝水
