Usually, for most healthy adults, drinking 2-3 liters of liquid per day should be sufficient, and even tea, soups, and juices contribute to the calculation. Your water amount will fluctuate based on temperature, activity level, and your body size, so you should see it as a guideline.
Eight glasses of water a day. You have probably already heard it from your fitness friends or your aunty. So where did that idea come from, and what does the science say?
The Short Answer to Your Daily Water Intake Question
Scientists from the National Academies of Sciences, Engineering and Medicine (2004) concluded that the adequate total intake of fluid is about 3.7 liters in the case of men and 2.7 liters for women. It is worth remembering that about 20% of fluid intake will be in the form of food; thus, the average intake of water will be around 3 liters in the case of men and 2.2 liters in the case of women.
Things that contribute positively to your number:
- Hot, humid weather (hello, sweaty commute)
- Exercise, especially hot and sweaty ones
- Pregnancy or breastfeeding
- Fever, vomiting, or diarrhea
- A high-protein or spicy diet
Why Your Body Cares (Besides Avoiding Headaches)
Water helps us to control the temperature, transport nutrients, and cushion the joints. Popkin, D'Anci, and Rosenberg (2010) review these facts in Nutrition Reviews. Moreover, Armstrong et al. (2012) claim that even losing 1.5% of body water makes mood and concentration of young women worse. Therefore, feeling grumpy in the afternoon can be caused by thirst disguised as being moody.
Hydration of Your Bean-Shaped Filters
At the end of hydration, it becomes possible to understand hydration's effect on kidneys. Two small fist-sized kidneys filter 180 liters of fluid in one day, and they will perform better when there is enough liquid in the organism. Borghi et al. conducted the famous experiment in the Journal of Urology, which followed people with recurrent stones. People with sufficient water consumption (more than 2 liters of urine) experienced a recurrence rate of 12% in 5 years, but this rate was 27% in the control group.
But more isn't always better. CKD WIT trial (Clark et al., 2018, JAMA) instructed people with chronic renal disease to drink an extra amount of water, but this did not slow the rate of their kidney function loss. In fact, some patients with advanced renal failure have certain water restrictions. Therefore, your nephrologist's recommendation is better than any recommendation from the Internet, including mine.
Where Ayurveda fits in
Many people who live with a chronic disease like kidney issues use complementary medicine and lifestyle changes besides the regular medical treatment. In Ayurveda, this mainly includes diet modification, changing habits, and taking certain herbs. Ayurveda considers punarnava, gokshura, and varuna the most beneficial herbs for kidney diseases. Most of these herbs have limited research, so they are traditional remedies rather than scientific cures.

Tips on Recognizing That You Are Performing the Technique Correctly
- Pale straw-colored urine means you are golden. Dark amber means time to get some water.
- Thirst is a valid signal, so listen to it.
- Drink your water in portions during the day instead of chugging one liter at 9 pm.
Can you overdo it? Rarely, but yes. In extreme situations, you can cause yourself hyponatremia. But you have to work quite hard to do it.
And yet, talking about natural treatment, you need to remember that it can only play the role of an addition to regular medicine, but not the main option.
Conclusion
Instead of searching for the exact magical figure, remember to aim for about 2-3 liters of fluid per day. Pay attention to the color of your urine, adjust the amount of fluid consumed according to the level of sweating and the current weather conditions, and consult your doctor if you are aware of any specific needs or restrictions concerning fluid intake or filters.
If you are interested in natural treatment options for kidney problems, you may wish to contact clinics such as Karma Ayurveda, where kidney diseases are treated with the help of Ayurvedic procedures recommended by Dr. Puneet Dhawan.
