Is it useful to drink more water when the virus catches a cold?

Keep drinking water after a cold, but don't drink a lot at a time. Drink water intermittently. Drink about one cup at a time, no more than 300 ml, and then drink it after a while. Don't drink one cup after another, it's too heavy for the kidneys. The amount of drinking water a day should not exceed 2000 ml. This can not only maintain the demand for drinking water for the common cold, but also have no effect on respiratory tract infection. Under normal circumstances, doctors will advise patients with colds to drink more boiled water, because colds are viral infections or secondary bacterial infections. Drinking more water helps to increase urine output and indirectly eliminate toxins in the body, especially when urinary tract infection occurs, which is beneficial to flushing bladder and rehabilitation. However, drinking more water is not recommended for cold patients with severe virus infections such as bronchitis and bacterial pneumonia. Because drinking more water will increase the secretion of antidiuretic hormone, because it can retain liquid by stimulating the kidney collection tube to reabsorb water. If extra liquid is given when the secretion of antidiuretic hormone increases, it will cause excessive water in the body, electrolyte imbalance, and may cause symptoms such as hyponatremia and excessive liquid load.
