The National Academies of Sciences, Engineering, and Medicine of the United States determined that an adequate daily fluid intake for men is approximately 15.5 cups (3.7 liters) and for women approximately 11.5 cups (2.7 liters).
While the amount of water you need is still a subject of debate (drinking too much of it can have adverse effects on your health), most studies believe that drinking 3-4 litres of water every day can give you a radiant skin, better immune system, and healthier heart.
This means you must keep sipping on at least 150-200 mL of water every 15 minutes if you sweat a lot. So, on an average, consume 4-5 liters (women) or 6-7 liters (men) of water for weight loss (if you participate in vigorous workouts regularly and tend to sweat a lot).
Drinking water is an excellent idea, BUT 5 litres a day is harmful. Generally speaking adults need about 1,5 to 2 litres of FLUID a day. If it is very hot and/or you do strenuous exercise then you can probably increase your fluid intake to 3 or 3,5 litres a day (depends how much liquid you lose by sweating).
If you drink too much, your kidneys can't handle that huge amount of water. This also happens if, for example, you drink 4 liters of water in a short time (without exercising intensively in the meantime). The excess of water causes a shortage of sodium in your blood: then you have a water poisoning .
A healthy adult needs around 35 ml of water each day per kilogram of body weight . At least according to the general guidelines from scientific organisations. A person weighing 50 kilograms requires 1.7 litres, 60 kilograms 2.1 litres, 70 kilograms 2.4 litres and 80 kilograms 2.8 litres.
"Drinking more than the kidneys can eliminate could cause hyponatremia in some people," says Hultin, noting that the kidneys can eliminate 27 to 34 ounces of water per hour, or a total of 676 to 947 ounces (20 to 28 liters) per day. More than that might put you in the danger zone.

You'll urinate more. You'll feel less hungry and may even lose weight. You'll probably experience more comfortable digestion (less heartburn). Bowel movements might be easier and more regular.
The symptoms of overhydration can look like those of dehydration. When you have too much water in the body, the kidneys can't remove the excess liquid. It starts collecting in the body, leading to nausea, vomiting, and diarrhea. Throbbing headaches all through the day.
A simple way to gauge your level of hydration is to pay attention to the color of your urine. If your urine is very dark and has a strong odor, you are definitely dehydrated and should increase your water intake. If your urine is completely clear, you are likely drinking too much.
If dark urine does not go away even after drinking plenty of water or traces of blood in your urine, seek medical attention immediately. Urine can change colour and take on a darker hue depending on what is causing it: dehydration, medications, one's diet, or a health condition.
You might have an electrolyte imbalance: Electrolyte imbalances are one of the most common reasons you might feel dehydrated even after drinking tons of water: “Sometimes if we drink a lot of water but we don't take in enough fruits and vegetables, our electrolytes—sodium, potassium, magnesium, chloride, etc.
A more calculated way to look at it is – drink a litre of water per 25kg of bodyweight, so if you weigh 50kg that's around 2 litres of water per day and if you weigh closer to 75kg you should be drinking broadly 3 litres per day.
Wondering how much water you should be drinking per day? A simple equation to figure it out is by drinking 33ml for every kilogram of body weight. Example - You weigh 100kg. 100 x 0.033 = 3.3 litres per day.
Water (in litres) to drink a day = Your Weight (in Kg) multiplied by 0.033. For example, if you are 60kg, you should drink about 2 litres of water every single day. At 90kg, you'll around about 3 litres of water. All you need to do is multiply 0.033 to your weight in Kg.
Drinking 3 litres of water per day is a simple and effective way to support your overall health and well-being and by staying hydrated, you can improve your digestion, boost your energy levels, and support your immune system.

Women should have about 2 litres (8 cups) of fluids a day, and men about 2.6 litres (10 cups). Women who are pregnant or breastfeeding need more fluid each day than other women. Dehydration can happen when the body's fluids are low. It can be life threatening, especially to babies, children and the elderly.
