Often we think that drinking water is a simple task. If you felt thirsty, you drank; if you didn’t, you didn’t drink. But do you know that kidneys are always working in our body? The function of the kidneys is to purify the blood, remove waste from the body, maintain salt and water balance, and control blood pressure. If we drink more or less water, it directly affects the kidneys.
Effects of shortage and excess of water
- by drinking less water–
When you do not drink enough water, dehydration (lack of water) occurs in the body. It affects the urine, due to which the urine becomes thick. Pressure on the kidneys increases, the risk of stone formation increases and urine infection may occur. In the long run, this can cause kidney disease. Even mild dehydration can affect brain function, mood and physical ability. - by drinking more water–
Many people think that drinking more water will be more beneficial. But drinking excessive water can also be harmful. Especially when you drink more than 3-4 liters of water in a short period of time, it can reduce the sodium level in the blood. This is called hyponatremia, whose symptoms can include headache, confusion, dizziness, and in severe cases, seizures or fainting.
caffeine and sugary drinks
Some people think that drinking tea, coffee or juice fulfills their water needs. But this is not correct. Caffeinated beverages (such as tea and coffee) can cause the body to lose water quickly, and beverages with high sugar content add additional burden to the body. Therefore, plain water is the safest and better option.
Avoid waiting to feel thirsty
Often we wait to feel thirsty, but by the time we feel thirsty, the body is already slightly dehydrated. This means that the kidneys are already working extra hard. Therefore, the best way is to keep drinking water little by little throughout the day.
right way to drink water
You can estimate the correct amount of water by the color of urine:
- Light yellow color: a sign of proper hydration
- Dark yellow color: sign of lack of water
- Like clear water: a sign of too much water (sometimes)
How much water should one drink?
In general, women should drink about 2.2 liters and men should drink 3 liters of water per day. But kidney patients, heart disease, diabetes, pregnant women and elderly people should decide the amount of water with the advice of the doctor. In these situations, both too much or too little water can cause problems.
