The water in the human body …

1. Water, after oxygen, is the second most important substance for human health. Roughly 70 percent of an adult’s body is made up of water.

2. Human blood is 83% water. 75% of brain and 25% of bones are made up of water.

3. By the time a person feels thirsty, his or her body has lost over 1 percent of its total water amount.

4. A person can live without water for approximately one week, depending upon the conditions.

5. Although many nutritionist and doctors tell patients to drink eight glasses of water a day, there is no scientific evidence to support this advice. You should be careful because drinking too much water causes the sodium levels in the bloodstream to dilute causing imbalance of water in your brain. This is called ‘water intoxication’ and lead to fatal cerebral and pulmonary edema.

6. Water serves many purposes within our bodies including:

  • Temperature regulation
  • Elimination of toxins and waste
  • Transportation of oxygen
  • Provides nutrients
  • Facilitates all chemical reactions within the body.
  • Digestive assistance.

7. Once you drink water, it leaves your stomach in about 5 minutes! Four hundred gallons of water are recycled through our kidneys each day.

8. Our bodies naturally loose between 2-2.5 litres of water per day through the action of the metabolism, movement and all of the millions of the bodily functions that occur within our body over the course of the day.

9. Lack of convenient sanitation and safe water supply in cities leads to serious health problems. Inadequate sanitation facilities often cause contamination of drinking water. Contaminated drinking water results in cholera epidemics, faecal-oral diseases such as diarrhoea, and outbreaks of malaria.

10. Pure water (solely hydrogen and oxygen atoms) has a neutral pH of 7, which is neither acidic nor basic.

Did you know that …

1.      Water is everywhere—there are 332,500,000 cubic miles of it on the earth’s surface. Most of the water is in the ocean, >97% and it is salty and undrinkable. Less than 1 percent from total water amount is fresh and accessible.

2.      Much more fresh water is stored under the ground in aquifers than on the earth’s surface.

3.      Reservoirs of water include: the oceans, ice, atmosphere, groundwater, lakes, rivers and streams, and living things. Water moves between reservoirs at different rates and by different processes, including: evaporation, condensation, precipitation, transpiration, and the flow of water.

4.      Water in the stratosphere contributes to the current warming of the earth’s atmosphere. That in turn may increase the severity of tropical cyclones, which throw more water into the stratosphere. That’s the theory, anyway.

5.      The United States uses about 346,000 million gallons of fresh water every day.

6.      In developing countries, 70% of industrial waste is thrown straight into the water without any additional procedures for their purification.

7.      Every day, 2 million tons of human waste are disposed of in water courses.

8.      Over 1.5 billion people do not have access to clean, safe water.

9.      27% of the urban dwellers in the developing world do not have access to piped water at home.

10.   The relationship between water and cities is crucial. Cities require a very large input of freshwater and in turn have a huge impact on freshwater systems.
