Wie schlecht ist Leitungswasser für deine Gesundheit


How much do you really know about your tap water? Is tap water healthy water, or should you only use filtered things? What influence does tea have on your water or water on your tea? In addition, many rumors are circulating about heavy metals, fluorides, chemicals and hormones in tap water, which make it dangerous!

You will find out what the reality looks like and which studies confirm this in this detailed blog post.

2. Is tap water healthy water?

Regardless of whether we need water for tea, coffee or for cooking, we usually use tap water for it.

But is this water actually harmless and healthy, as is suggested to us, or is it perhaps dangerous? We use several liters and water every day is considered a life donor, so it is extremely important that this everyday good is of the highest quality.

Before we go into the details and take a look at how bad or good tap water is for health, I can say in advance: The study situation does not allow anything good! Healthy water should be free of hormones, chemicals and heavy metals, but unfortunately our tap water has given it.

Therefore, tap water is not fundamentally dangerous. What matters, what you have to consider and how you can make bad water yourself drinkable again, we will be right away.


3. Is hard or soft water better?

A question that is much too often discussed is about hard and soft water. Companies like to jump on this train with plenty of advertising and suggest that soft water is healthier. 

Soft water tastes better, but is neither healthier nor historical. Strictly speaking, hard water is even a great supplier of magnesium and calcium and stabilizes the pH in the alkaline area.

The only disadvantage is shown in the kettle, and taste, both suffer from it.

In general, you don't have to worry about your health in hard water.


4. Chemicals & hormones in drinking water - study reproduction

In many countries, chemicals are used to make the water drinkable at all, in Germany and the entire roof region, this is rarely the case. 

Nevertheless, a lot of chemicals find their way into our drinking water. Just think of your washing machine, the many industrial plants, or car streets, they are all connected to our sewage system.

And our sewage system, after cleaning, leads into the rivers, from which we then relate our drinking water. 

In large cities there are often preparation systems that form a circulation between consumption and preparation so that you drink what ended up in the toilet the evening before.

The preparation systems are incredibly good, obvious, but they cannot filter all chemicals entirely from the water. This means that your tap water is not directly dangerous or toxic, but long -term consequences for your health can occur.

These chemicals have an impact on our hormones and can damage our entire reproductive system.

It's noisy Studies Clearly that these chemicals cause dysfunction of female egg production, male sperm production and thus general fertility. 

According to the study, the probability of an unfavorable pregnancy also increases. The lifespan of sperm also decreases.


5. Dangerous chemicals and hormones in tap water

Chemicals that are classified as dangerous in our tap water are the following:

  1. Disinfection
  2. Fluorides
  3. BPA
  4. Pesticides
  5. Estrogens

These chemicals and hormones in our drinking water are according to the Federation for the Environment and Nature Conservation Germany contained in too high quantities in our tap water.

According to this analysis, our rivers in Germany, as in South Hesse, are filled with up to 100 % wastewater content at low water. In other areas, it does not look better with 25 % to 60 %.

You cannot filter our filter systems of the municipal utility 100 % and not 99 % of the chemicals and hormones of our wastewater, according to the study, they return to our drinking water.


6. How dangerous is tap water?

The hormones and chemicals in drinking water mentioned above can be Study on fluorides in drinking water trigger the following serious illnesses.

  1. Damage to the thyroid gland and thus:
    1. Metabolic diseases
    2. sleepiness
    3. Energeticiness
    4. depressions
  2. Cancer, such as
    1. Breast cancer with latency of up to 20 years
    2. Salicous changes in the genital organs
    3. Cysts of the ancillary hotel, too small testicles, testicular high level, too small penis
    4. Low sperm number
    5. Reduced seed volume
  3. Impairment of brain development in children
  4. Immune deficiency


7. Tap water filter systems - water for home 

Now of course the question arises whether you should filter your water.

It depends very much on you personally and the region in which you live.

If you have no problems with your metabolism, your mood or your sleep, it may not be necessary to filter your water at the moment.

But some diseases such as cancer are sometimes only evident after decades, which is why preventing can be good

I would therefore like to show you two possible variants of water filters, filter systems, their mode of action and efficiency for at home.

7.1. Gravity water filter

You can imagine these handy filters like a water carafe. They are definitely suitable for a single household and use water for tea. 

However, you have to be careful. Not all dealers offer sufficient qualitative filters. Often gravity water filters only filter lime and thus only make the water softer. 

When buying, make sure that the filter filter fluorides, chemicals and hormones. For example, you can at the company "Invigorated Water"Look.

7.2. Osmosis water filter

Osmos filter for healthy water drinking water without hormones

An osmosis system is the strongest form of water filtering. The pressure of the water connection is used here. This presses the water through several filters, which gradually filter out the individual components of the water.

Filtered water from an osmosis system is therefore the purest water that you can get. Even hormones are removed.

The disadvantage of this water filtering is that also good components such as magnesium and calcium are removed.

However, if you use the water mainly for tea or for cooking, cleaning the water via osmosis is best.

Osmosis water is also suitable for drinking. However, it is usually recommended to enrich the water again with minerals. This takes place automatically when preparing a tea.

Guayusa-Leaves For example, contain sodium, potassium, zinc, phosphorus and magnesium

Osmosis systems in all variants can be found in the following two providers: iSpring and Osmofresh.


8. Which water for tea?

Teet drinkers will always tell you the same thing: "For a good tea you need soft water!"

The reason why soft water is more suitable for tea is that components of the tea, such as minerals, but also flavors and active ingredients such as caffeine, can develop easier if the resistance from other components in the water is missing.

Everyone knows the chemistry experiment separated by a membrane in the low-salt water and salty water. After a while, the salinity has adjusted in both areas, but at the end of the alignment, the exchange is becoming increasingly slower. 

It is similar with tea. The active ingredients in Guayusa tea Have it easier to go into a healthy and clean water than in a hard one.

Hard water therefore affects both the taste and the number of active ingredients.
