Proper Hydration: Many people drink water only when they feel thirsty. However, this habit can be harmful. Let's find out what doctors say.

Disadvantages of drinking less water

What Happens If You Don't Drink Enough Water: Most of us take drinking water for granted. If we're thirsty, we pick up a glass, and if we're not, we leave it. But the kidneys can't tolerate such carelessness. These tiny organs clean the blood, remove toxins from the body, maintain electrolyte balance, and regulate fluid levels. When the body doesn't get enough water, the kidneys have to work harder. This isn't just a matter of fatigue, but in the long run, it can increase the risk of kidney stones, urinary tract infections, and chronic kidney disease. Let us tell you what experts say about this and what precautions we need to take.

What is the misconception among people about water?

Many people believe that drinking tea, coffee, or juice throughout the day is sufficient. However, caffeine and sugary drinks can rapidly deplete the body of water. Another misconception is that one should only drink water when thirsty. The truth is that by the time one feels thirsty, the body is already slightly dehydrated, and the kidneys are under increased pressure. On the other hand, some people drink more water than necessary, thinking that more water is always beneficial. However, drinking three to four liters or more in a short period of time can be dangerous. This can cause blood sodium levels to drop, a condition called hyponatremia. In severe cases, it can lead to brain swelling, seizures, or even coma.

What does the doctor say?

Urologist Dr. Ajay Agarwal told TOI that the kidneys need a balanced amount of water. Too little or too much is harmful. Consuming too little water consistently can lead to concentrated urine, increasing the risk of kidney stones and infections. Furthermore, excessive fluid intake can put additional strain on people with diabetes or heart disease.

How much water should one drink?

Experts say the 8-glass rule doesn't apply to everyone. Generally, women need about 2.2 liters and men need 3 liters of fluid, but this depends on weather , perspiration, exercise, and health status. Urine color is a good indicator; a pale yellow indicates adequate hydration, a very dark color indicates dehydration, and a clear color may indicate overconsumption.
