I just watched a video on youtube "The Drink 8 Glasses Water Per Day Big Fat Lie!".
Dr. Berg goes through the 5 lies about drinking more water. It is one of those "everyone knows", so drink when you are thirsty. Hyponatremia is a condition whereby you can get really sick by drinking too much water. "Adolph EF. The regulation of the water content of the human organism. J Physiol (London). 192155(1-2):114-32" In short, the author measured his own urine and sweat output and determined he lost 3 percent of his body weight in water per day, which came out to be eight cups. Based on this, for a long time the water requirement guidelines were eight cups. However, this is not the case anymore except that most people still know the saying: eight glasses of water a day. "Vivanti AP. Origins for the estimations of water requirements in adults. Eur J Clin Nutr. 201266(12):1282-9."
Please, share your opinion.
I am far from being able to count the amount of water I drank. I am like an beast: if I want to drink - I drink. Of course, the water balance will vary with the seasons. In winter, we have in the Urals -30 C, and in summer +30. At a minimum, the amount of water should depend on the outside temperature, humidity and physical activity.
