还真有喝水喝死的…

[FoxNews] An investigation into how Shaun McNamara died revealed that he drank himself to death after consuming too much water. His body was found on the floor of his bathroom last September.

At first, doctors thought McNamara had suffered a heart attack. It was not until an autopsy revealed that he had downed so much fluid, so fast, that his brain had swollen, the Mail reported.

"In 35 years as a pathologist I have never come across such a case," said Dr. Ian Reed, who carried out the autopsy.

Water intoxication, also known as hyponatremia, normally is linked to marathon runners' drinking too much water after a race. When this happens, there is so much water in the body that it dilutes vital minerals such as sodium down to dangerous levels. This can lead to confusion, headaches and in extreme cases fatal swelling of the brain, according to the report.

-------------------------
Hyponatremia - Water Intoxication,低钠血症,水中毒。大量喝水后体液中电解质浓度过低,造成细胞内外的浓度差从而使细胞膨胀,可造成心率不齐、肺水肿(听起来像高原反应...)、癫痫、昏迷.....死亡。一般在婴儿及运动员人群较为多见。

嗯,我喝水也算很多的了。而且市面上的运动饮料,喝完了跑步时嘴里粘粘的很不舒服,所以一般都是直接带一大瓶清水。但确实有过头晕之类的脱水症状,个么也要考虑一下运动配方了。

WHO有ORS(口服补液盐)的配方,用于腹泻后迅速补充水分,本质上和运动补液是一样道理,完全可以拿来用,市面上也有成品卖,不知道味道怎样。

不过ORS的重点在于如何模拟体液的浓度,以便虚弱时能更好吸收。一般运动的话,似乎也不用搞的这么专业,往水里加些食盐和葡萄糖,应该也就可以了吧。

  1. 葡萄糖....不怕被发馒头啊?呵呵。

    糖盐水喝过,口感不好 :-(

    这两天出去骑车,结果随身带的清水经常喝不完,经常是回来路上灌运动饮料,稍奢靡了。目前最爱的是维体和佳得乐。出汗之后确实很爽口。
