Drinking water can also be poisoned

High temperatures in the week, many people get hot heat, and even heat out the heat. In fact, everyone knows that you should drink more water to prevent heatstroke and heatstroke. However, it is very likely that there will be "water poisoning" when you drink more water. Last Tuesday, Ningbo Second Hospital received a “water poisoning” patient.

Even after drinking five large bottles of boiled water, body convulsions

It is understood that Master Wang is a construction worker. When he was working on the construction site that morning, he felt very tired, so he sat down in the shade to rest. After that, Master Wang felt that his body was still sweating a lot. He feared that the body lost too much water and drunk five bottles of boiled water. I thought that after drinking water, my body would be better, but after a while, Master Wang showed a whole body convulsion. After the workers found it scared, they quickly sent him to the emergency department of the Second Hospital of Ningbo City. After the diagnosis, Master Wang appeared "water poisoning". Last week, the Ningbo Municipal Center for Disease Control and Prevention also learned about a case of water poisoning. The public, He Laobo, had a little water because he had some symptoms of heat stroke. As a result, he became more and more serious and had to be sent to the hospital for rescue. The doctor's diagnosis is also "water poisoning."

Drinking water at 100 to 150 ml at a time

Liu Peng said that "water poisoning" is generally caused by a large amount of drinking water, especially during summer physical labor and strenuous exercise. In high temperature environment, especially the symptoms of heatstroke have appeared, the body has lost water and electrolytes, and drinking plenty of boiled water for a short time is actually a big taboo. The reason is that the maximum diuretic speed of the human kidney is 16 ml per minute. Once the rate of water intake exceeds this standard, excess water will cause the cells to swell, causing dehydration and hyponatremia. "Like Master Wang, who drank five bottles of boiled water for a short time, but did not simultaneously add electrolytes, causing electrolyte imbalance in the body, dizziness, vomiting, weakness, rapid heartbeat and other symptoms, serious convulsions, coma and even endangered Life." Liu Peng explained. Liu Peng reminded that when high-intensity labor or a lot of sweating, if you are thirsty, you can't drink it once. You should drink it several times, and drink less, in order to facilitate the body's absorption. It is recommended to drink 100 ml to 150 ml each time, with an interval of half an hour. In addition, you should drink water regularly, whether you are thirsty or not.

It is best to add light salt water after a lot of sweating.

After a lot of sweating, it is not enough to only add water, but also add trace elements such as sodium and potassium. Liu Peng suggested that people who want high-temperature work or strenuous exercise in summer should preferably supplement light salt water, light sugar water or sports drinks to maintain the electrolyte balance in the body. Adding salt to the boiled water is light salt water, and the concentration is generally recommended to be 0.9%. It doesn't matter if the concentration is not well controlled, as long as it is a bit salty. Strong physical workers, sweating more quickly, if you feel limb weakness, it is best to add a little sugar on the basis of light salt water, which is light sugar brine. In addition, do not drink cold drinks below 5 degrees Celsius after outdoor sports and work. At this time, due to the high body temperature, drinking a lot of cold drinks can easily hurt the stomach and cause digestive diseases. Liu Peng said that the real thirst quenching is 20 ° C -30 ° C warm water. Because warm water can cause blood vessels to dilate, promote perspiration, bring heat out of the body, so that the body temperature really drops, then it will feel very cool.
