You can choose to quench your thirst by drinking plain or purified water on a daily basis. If you have lost a lot of water or are dehydrated, you can choose to drink saline water to quench your thirst. Water is involved in the body’s metabolism and helps the body eliminate waste through urine or feces. Under normal circumstances, when thirsty, drinking plain water or pure water is enough for the body’s needs. However, if the body loses a lot of water after strenuous exercise or severe diarrhea, you can drink a moderate amount of saline water to help maintain the balance of electrolytes in the body. It should be noted that the daily water can be replenished on a regular basis, without the need to feel thirsty and then drink water. And although water is involved in human metabolism, is an indispensable component of the human body, but should not drink too much water. So as not to aggravate the burden on the kidneys. If you feel uncomfortable after drinking water, you should consult a doctor in time.
