Turn on the tap and off you go: Pure water is essential for us - and not just when it's hot. Because it regulates our cardiovascular function and our digestion, it is a solvent for salts and minerals, transports nutrients and decomposition products and regulates our heat balance. In short: it is our elixir of life. More important facts about our drinking water:
How healthy is tap water?
Very healthy! The Federal Environment Agency regularly has samples tested, and in the last study 99 percent of them were rated as "very good". Additional filters are not only unnecessary, they can actually contaminate the water.
Where does our mineral water actually come from?
It comes from an underground spring and has been enriched with various minerals on its way through the layers of rock. It is bottled directly at the source and is the only foodstuff in Germany to be officially recognized.
Which is better: glass or PET?
Scientists at the University of Frankfurt have discovered that water from PET bottles is contaminated with more hormones than water from glass bottles. Whether the quantities are hazardous to health is controversial. If you want to be on the safe side and do something good for the environment, it is better to use reusable glass bottles.
How much water should I really drink?
Doctors recommend drinking around 1.5 liters of water a day - preferably evenly distributed: Our body cannot process more than 500 milliliters per hour. Drink more than usual in hot weather and during sport. But don't overdo it: Otherwise our body will excrete important minerals in the urine.
Where can I cleverly save drinking water in the household?
It's important to know in advance: Saving is less worthwhile for the environment. Because if too little water flows through the sewer system to keep the pipes clear, the waterworks have to flush it out. But it is worthwhile for our wallets if we take a shower instead of a bath and install a special aerator as a shower head - this saves up to 50 percent water. Another great idea is to collect rainwater in a collection system and use it for watering and flushing the toilet.
