Did you know that water makes up more than two-thirds of the weight of the human body? And that over 90% of the weight of the blood in our veins is water? Here are some other amazing water facts:
- Water is the only substance on Earth that is naturally found in all three states of matter – solid, liquid, and gas and earth is the only planet in the Solar System that has water in all three states.
- About 70% of the human body is made up of water. the brain and heart are composed of 73% water, and the lungs are about 83% water. The skin contains 64% water, muscles and kidneys are 79%, and even the bones are watery by 31%.
- A single drop of water contains more atoms than there are stars in the Milky Way galaxy. This is inconceivable and hard to believe. (Am not kidding, there are heated arguments about it on quora and reddit)
- Each person uses about 142 litres of water each day. The average household uses 349 litres of water each day1. The average annual metered water bill is £4272.

- There are two kinds of water; salt water and freshwater. Salt water contains great amounts of salt, whereas freshwater has a dissolved salt concentration of less than 1%. Only freshwater can be applied as drinking water.
- In a 100-year period, a water molecule spends 98 years in the ocean, 20 months as ice, about 2 weeks in lakes and rivers, and less than a week in the atmosphere.
- Every day, the human body loses around 2.5 litres of water, which is why it’s so important to stay hydrated.
- Groundwater can take a human lifetime just to traverse a mile.
- If water changes phase its physical appearance changes due to parting of water molecules. In the solid phase the water molecules are close together and in the gaseous phase they are the furthest apart.
- Frozen water is 9% lighter than water, which is why ice floats on water.
- It takes around six litres of water to produce a single egg.
- It takes around 2,400 litres of water to produce one kilogram of rice.
- It takes around 15,000 litres of water to produce one kilogram of beef.
- It takes around 5,000 litres of water to produce one pair of jeans.
- Every drop of water on Earth has been around for at least 3.8 billion years.
- Humans can only survive without water for 3-5 days but can survive a month without food.
- It takes about 1,800 litres of water to produce one litre of gasoline.
- The largest swimming pool in the world is in Chile and it holds 250 million litres of water.
- Less than 1% of the world’s fresh water is readily available for human use.
- The water you drink today might be the same water that a dinosaur drank millions of years ago? That’s because water is constantly being recycled through the Earth’s atmosphere, oceans, and land.
Water is one of the most powerful forces on Earth. It can carve canyons, create mountains, and even move continents so the next time you take a sip of water, we hope you remember how powerful water is. What water facts can you think of that we might have missed?
