Water is important for life

Water is essential
Water has many different functions in our body. The most important thing for the kidneys and brain is that the kidneys wash away substances from our body that it no longer needs or that are even toxic. And our brain wants to be constantly supplied with nutrients so that it can work well. Our blood transports these nutrients to him – as well as to all other organs in our body and to our muscles.Scientist from the Institute of Pharmacy at the Friedrich Schiller University in Jena lets blood drip from a pipetteThe vast majority of blood is water.

The vast majority of blood is water. It circles through our bodies again and again, brings nutrients wherever they are needed and picks up waste. The blood circulates in our body so often that a total of 2,000 liters of water flow through the kidneys and 1,400 liters through the brain.

Don’t get us wrong: Of course we don’t have that much blood in our bodies, but only about 4-6 liters per person. But they circle so often that up to two thousand liters a day flow through the organs. Got it?

Our body loses water again and again, but that is also vital for it: when we have to go to the toilet, where we get rid of the waste materials, when we sweat and our bodies cool down – and even when we exhale, because it is always too a little water vapor in our breathing air. Without water we could only survive two days. So drinking is vital! Children need about one to two liters of water every day and adults need two to three liters of water.

Not just for drinking

Needs a lot of water: the washing machine.

For personal hygiene, washing clothes, cooking and washing up and for everything else that we do with water, every one of us here in Germany uses about 130 liters of drinking water every day – that’s 13 big buckets full.We only take five liters – half a bucket – for drinking and eating. We wash down seven times as much in the toilet every day: about 35 liters. A good bucket of water trickles out of the shower every minute. 12 to 18 buckets fit in a bathtub: up to 180 liters!A girl plays with the water fountains on August 1st, 2017 at the fountain at Stachus in Munich (Bavaria)
Wonderful: the fountain at Karlsplatz in Munich in summer!

And water is also used elsewhere: we look forward to fountains in which water bubbles, the fire brigade needs to extinguish the fire, we water our flowers with it and the farmer waters the plants in the field so that he can later harvest the fruit.Water is also used in the factories: for example for paper production, but also for paper recycling. By the way, 10 liters of water are required to produce a single sheet of paper!

Drinking water

You can drink the least

Water (H 2 O) is a chemical combination of the elements oxygen (O) and hydrogen (H). As a liquid , water is transparent, largely colorless, odorless and tasteless. It occurs in two isomers (para- and ortho-water) that differ in the nuclear spin of the two hydrogen atoms.Water is the only chemical compound on earth that occurs naturally as a liquid, as a solid and as a gas . The term water is used for the liquid state of matter . In the solid state one speaks of ice , in the gaseous state water vapor . Water is the basis of life on earth. In nature, water rarely occurs in pure form, but mostly contains dissolved portions of salts, gases and organic compounds.
There is plenty of water on earth: three-quarters of it is covered with water. But: Most of it is salt water, which you cannot drink. And of the little fresh water there is, most of it is still frozen: in glaciers and ice sheets. So only one thing helps:

Save water

Save water! For example like this:
Collect rainwater and water the flowers!
You can also water flowers with the water used to wash vegetables in the kitchen.
Don’t waste so much paper, so you don’t have to make or recycle as much.
It is better to take a shower rather than a bath, you need a lot more water for a full bath.
Use the economy button on the toilet!
