How important healthy water is for our health

So wichtig ist gesundes Wasser für unsere Gesundheit

Water is the basis of life – about 70% of our bodies are made of it. For most people in industrialized countries, drinking tap water or simply buying a bottle of water is part of everyday life. But which water is best for our health? And what about the quality of tap water? In this blog post, we explore the importance of clean drinking water and discuss the potential risks of tap water as well as the benefits of water filters.

The importance of clean drinking water for health

The human body needs water for almost all vital functions: It regulates body temperature, supports metabolism, ensures smooth digestion, and transports nutrients to the cells. Clean and healthy drinking water is therefore essential. Regular consumption of pure water promotes overall health, improves performance, and can reduce the risk of disease.

The role of water in the body

Water is involved in numerous important functions in the body. These include:

  • Regulation of body temperature: Through sweating, water ensures that body temperature remains constant, especially in hot weather or during physical exertion.
  • Transport of nutrients: Water is the carrier medium through which nutrients such as vitamins and minerals reach the cells.
  • Detoxification of the body: Water helps to remove waste products and toxins from the body through the kidneys and urine.
  • Digestive support: Water is needed to aid digestion and keep the intestines healthy.
  • Protection of organs: Sufficient water protects organs and tissues, especially the joints, and serves as a lubricant for our joints.

Inadequate water intake or consumption of contaminated water can disrupt these vital functions and lead to health problems.

Drinking tap water: Is it really safe?

In Germany, tap water is considered one of the most strictly controlled foodstuffs. Nevertheless, concerns about water quality continue to arise, prompting the desire for additional water treatment. Many people ask, "Why shouldn't we drink tap water?" The answer is complex:

Although tap water is considered safe to drink, contamination with pollutants, heavy metals (e.g., lead and copper), hormones, and drug residues is not uncommon. These substances enter the water system via the environment, industrial wastewater, and human consumption. Wastewater treatment plants cannot completely remove all residues, meaning these contaminants can remain in the water.

The impact of contaminated water on health

If the water we drink every day is contaminated with pollutants, it can have negative effects instead of supporting our health. A particularly worrying aspect is the contamination of tap water with heavy metals, drug residues, pesticides, and hormones.

  • Heavy metals: Metals such as lead, mercury, and copper, which can be found in water flowing through old pipes, are particularly dangerous. They build up in the body over time and can lead to chronic diseases, including neurological damage, kidney damage, and a weakened immune system.
  • Hormones and drug residues: Through the use of medications and hormonal contraceptives, tiny amounts of hormones and drug residues enter the groundwater and thus tap water via wastewater. Although these substances are present in small quantities, their long-term exposure can affect hormone regulation in the body, which can be particularly dangerous for sensitive groups such as children and pregnant women.
  • Pesticides and microplastics: Pesticides from agriculture and microplastics released into the environment through plastic pollution can also be found in tap water. These substances are suspected of being carcinogenic or disrupting the endocrine system.

Health risks from long-term drinking of contaminated tap water

Although many of the contaminants mentioned are often present in tap water only in small amounts, regular and long-term consumption can lead to serious health problems. Potential risks include:

  • Hormonal imbalances: Consuming water contaminated with hormones or drug residues can disrupt the natural balance of the endocrine system. This can lead to long-term hormonal problems such as fertility problems, thyroid disorders, or an increased risk of cancer.
  • Kidney and nervous system damage: Heavy metals such as lead and mercury, found in old plumbing, can accumulate in the body and cause kidney damage and neurological impairment. In children, lead poisoning can lead to developmental delays.
  • Increased cancer risk: Some pollutants found in water, such as pesticides and certain chemicals, are suspected carcinogens. Therefore, ingesting such substances through drinking water can increase the risk of various types of cancer.
  • Increased antibiotic resistance: Drug residues in drinking water, especially antibiotics, can contribute to the emergence of resistant bacteria. This antibiotic resistance poses a growing threat to public health because it complicates the treatment of infections.

Water filters: A sensible solution?

Against this backdrop, the question arises: "How useful is a water filter?" Water filters are an increasingly popular option for removing potentially harmful substances from tap water and thus improving water quality. They offer numerous advantages:

  • Filtering out contaminants: High-quality water filters effectively remove contaminants such as chlorine, heavy metals, microplastics, pesticides, bacteria, and drug residues. This reduces the risk of becoming ill from tap water.
  • Better taste: Many people report that filtered water tastes more pleasant. Chlorine and other chemicals that negatively affect taste are removed through the filtration process.
  • Cost savings: Compared to purchasing bottled water, water filters are more cost-effective in the long run. Drinking filtered tap water also avoids plastic waste, making it more environmentally friendly.
  • Practical and convenient: A water filter makes it possible to have clean water available at all times without having to rely on external sources.

Which water is best?

When comparing the different options—tap water, filtered water, and bottled mineral water—the question arises, "Which water is best?" From a health perspective, filtered tap water is often the best choice. It combines the convenience of tap water with the safety of purified water.

While mineral water can also be beneficial to health due to its natural mineral content, its high price, its ecological footprint, and the potential for microplastics in plastic bottles often make it unsuitable. Filtered water, on the other hand, offers a cost-effective, environmentally friendly, and safe solution. Water filters also add minerals such as magnesium, calcium, zinc, and selenium to the filtered water.

Why shouldn't you drink tap water?

In summary, there are several reasons why it may be advisable to avoid drinking unfiltered tap water:

  • Pollutants and contaminants: As mentioned above, tap water can be contaminated with heavy metals, drug residues, and hormones. These substances are not always present in harmful quantities, but their long-term intake could have health consequences.
  • Old plumbing systems: Some older homes may still have lead pipes or pipes containing other harmful materials that contaminate the water.
  • Uncertainty about the exact water quality: The quality of tap water varies by region, and many people do not have accurate information about the specific contaminants in their local water.

Conclusion

Clean and healthy drinking water is crucial for our well-being. Although tap water in Germany is generally safe, it can be contaminated with pollutants and heavy metals. To minimize health risks, using a water filter is a sensible solution. Filtered water provides the safety and purity our bodies need while being more environmentally friendly and cost-effective than bottled mineral water.
