Hello and welcome to our third installment about random water facts. In this blog we are looking at water and living things.
Anatomic and Anthropological View
- A person can live about a month without food, but only about a week without water.
- Your body is between 60% and 70% water. This changes at different times of your life: a human fetus is around 95% water for the first months, getting to 77% water at birth. In a 70kg person, there are 42 liters of water. Two-thirds of that water is within your cells.
- 75% of the human brain is water and 75% of a living tree is water.
- Human bones are 25% water.
- 70% of an elephant is water.
- We each drink around 1 cubic meter (1000 liters) of water a year.
- The weight a person loses directly after intense physical activity is weight from water, not fat.
- It is a little known fact, but insufficient water consumption is actually a risk factor for colon, breast and urinary tract cancers such as cancers of the kidneys, bladder, prostate, and testicles. Hydration is critical to blood circulation to allow immune system cells to reach damaged tissues in greater numbers.
- You should drink enough to equal ½ your body weight in ounces each day. If you weigh 140 lbs., drink 70 oz and if you weigh 200 lbs drink 100 oz.
- For every six ounces of caffeine or alcohol you consume, an additional 10 to 12 oz. of water is needed to re-hydrate you.
- We lose over 2 quarts (64 oz) of water every day through the normal vapor exchange of our skin, otherwise known as perspiration.
- By the time a person feels thirsty, his or her body has lost over 1 percent of its total water amount.
