A common health advice from doctors to people is: drink more water, but some people worry that drinking too much water will not be very tired kidneys? Will it be poisoned? It is true that “water poisoning” does exist, but the average person will not suffer Indeed, there is a concept of “water poisoning” in medicine, but generally does not happen in normal people, because the kidneys are the most important organ to excrete water, its urinary capacity is very strong, even if the kidneys The only thing that is possible is that the kidneys are heavily hydrated immediately after sweating, but the supplement is fresh water, and only then is it possible to be “poisoned”. If you drink a lot of water at once without replenishing salt, the salt in the blood will be reduced and the blood will become thinner, so some water will be absorbed into the tissue cells quickly and make the cells edematous, which causes “chronic water poisoning”. Dizziness, thirst, and in severe cases, sudden fainting, and in extreme cases, there is a possibility of death. But this is a very small probability event, mostly seen when playing forgetfulness, sweating, body sodium and salt and other electrolyte loss, and then a lot of drinking fresh water, but not enough salt. At this time, dizziness, vomiting, weakness, muscle twitching or pain, this is a mild “water poisoning” performance. Summer sports must be supplemented with salt water So, if you exercise a lot, especially in summer, it is best to supplement salt water, or sports drinks, ume water, tea and green bean soup can also be, the latter three are rich in potassium. However, if you do not sweat that much, sports drinks are better to drink less, which contain sugar and salt will aggravate the already excessive sugar and salt overload. In fact, now more people are not drinking more water, but less, from the “water poisoning” is far from. Especially people who are older, their kidneys will decline with age, the elderly drink water, will be more excreted, they should actually drink more water, but because they feel slower than young people, and mobility, not willing to go to the toilet, so in turn drink less water, especially the hot weather and dry spring and summer, which is a high incidence of cerebral thrombosis season, blood pressure is easy to low. If you don’t drink enough water, it’s easier to induce blood concentration, leading to the occurrence of “low perfusion stroke”. The best way to determine if you are dehydrated is not to be thirsty, but to look at the color of your urine. As long as the color of urine is yellow, it means dehydration, the more serious yellow dehydration more serious, drinking water moderate color of urine should only be a light yellow.
