How Much Water Does the Human Body Need Daily?
Adult men contain the next highest level of water. Adult women contain a lower percentage of water than babies or men. Obese men and women have less water, as a percentage than lean adults.
Water serves multiple purposes:. Water is the primary building block of cells. It acts as an insulator, regulating internal body temperature.
Water − the human body's major component
This is partly because water has a high specific heat, plus the body uses perspiration and respiration to regulate temperature. Water is needed to metabolize proteins and carbohydrates used as food. It is the primary component of saliva, used to digest carbohydrates and aid in swallowing food. The compound lubricates joints. Water insulates the brain, spinal cord, organs, and fetus.
It acts as a shock absorber. Water is used to flush waste and toxins from the body via urine.

Water is the principal solvent in the body. It dissolves minerals, soluble vitamins, and certain nutrients. Water carries oxygen and nutrients to cells. Water is essential for human survival. An adult body is made up of about 60 percent water, and a newborn is made up of 74 percent of water.
Water removes waste from cells, brings nutrients to cells, regulates body temperature and helps you digest food. Your hydration needs depend on exercise, diet, age, body fat, altitude, pregnancy, medications and the weather.
Amount of water in the human body
The average amount of water consumed for males and females is based on caloric intake. In general, you need 1 to 1. On average, a female needs 9 cups of water per day, and males need 13 cups per day. During the second trimester of pregnancy, women should increase their calorie intake, which in turn increases their water needs.
Pregnant women should get 8 to 10 glasses of water each day to account for higher blood volume, circulation for the fetus and amniotic fluid. Infants are prone to dehydration because of their age, but increasing the amount of breast milk or formula may help. In extreme cases, intravenous fluids may be needed.
