The common advice to drink 8 glasses (1,900 mL or 64 US fl oz) of plain water per day is not scientific; thirst is a better guide for how much water to drink than is a specific, fixed amount. [4] Americans aged 21 and older, on average, drink 1,043 mL (36.7 imp fl oz; 35.3 US fl oz) of drinking water a day, and 95% drink less than 2,958 mL (104 ...
A buffer solution is a solution where the pH does not change significantly on dilution or if an acid or base is added at constant temperature. [1] Its pH changes very little when a small amount of strong acid or base is added to it. Buffer solutions are used as a means of keeping pH at a nearly constant value in a wide variety of chemical ...
In pure water, there is an equal number of hydroxide and H + ions, so it is a neutral solution. At 25 °C (77 °F), pure water has a pH of 7 and a pOH of 7 (this varies when the temperature changes: see self-ionization of water). A pH value less than 7 indicates an acidic solution, and a pH value more than 7 indicates a basic solution. [7]
Many folks opt to aim for the nice, square number of 1 gallon of water a day (for reference, 2.7 liters equal about 0.7 gallons), so we looked into the health benefits of drinking that much H20 ...
The adult human body averages ~53% water. [7] This varies substantially by age, sex, and adiposity. In a large sample of adults of all ages and both sexes, the figure for water fraction by weight was found to be 48 ±6% for females and 58 ±8% water for males. [8]
The figure for water fraction by weight in this sample was found to be 58 ±8% water for males and 48 ±6% for females. [4] The body water constitutes as much as 75% of the body weight of a newborn infant, whereas some obese people are as little as 45% water by weight. [5] This is due to how fat tissue does not retain water as well as lean tissue.

The spokesperson for the Academy calls water, "the gold standard fluid for the body." Since the human body is about 60% water, after a night of sleep our bodies need to be replenished with water ...
