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.
The U.S. National Academies of Sciences, Engineering, and Medicine determined that an adequate daily fluid intake is: About 15.5 cups (3.7 liters) of fluids a day for men. About 11.5 cups (2.7 liters) of fluids a day for women.
On average our food is thought to contribute about 20% of our fluid intake which, therefore, suggests a woman should aim to drink about 1.6 litres and a man should aim for 2 litres.
An adult needs an average of 1.5 to 2 liters of fluid per day in the form of drinks. Exactly how much fluid you need depends on your age, temperature, exercise, what you eat and your state of health.

The next size up is the 1.5 liter. So we go from 750 ml bottle to 1.5 liter which is exactly double. I said you can get about 4 glasses from the 750, so I usually bang out about 9 glasses out of a 1.5 liter.

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.
Thus, water drinking provides a sympathetic stimulus, which increases the metabolic rate, i.e, thermogenesis, which in turn augments the daily energy expenditure.
You may start experiencing things like confusion, drowsiness, and headaches. If this pressure increases it could cause conditions like hypertension (High Blood Pressure) and bradycardia (Low Heart Rate). Sodium is the electrolyte most affected by overhydration, leading to a condition called hyponatremia.
In fact, even mild dehydration affects your blood vessels (making them less springy) about the same as smoking a cigarette. Skimping on water also leads to less blood in your body, which can lower your blood pressure and raise your heart rate. It takes just 15 to 20 minutes for enough water to even things out.
Daily fluid intake

1 The study authors calculated that people burn 50 calories per 1.5 liters of water. This would be about 17 calories per water bottle (0.5 liters), the equivalent of 4 M&M candies. The authors estimated that a third of the calories burned after drinking are due to thermogenesis (5 to 6 calories per water bottle).
