Drinking bottles in test: These are the best materials

The human body needs at least 2 liters of fluid daily to function. In the hectic pace of everyday life, however, we often forget to drink water. According to statistics, only every second German manages to consume the recommended amount. Insufficient water consumption leads to lasting damage to bodily functions. The consequences: severe headaches and backaches, fatigue and a dry mouth, then quickly make themselves felt. Fortunately, the problem has a very simple solution. A drinking bottle enables controlled fluid intake and can prevent dehydration. That’s why for many, the reusable water bottle has become a faithful companion for sports, work and leisure. But not all water bottles are the same. Those who want to do something good for themselves and their bodies opt for a sustainable design made of metal or glass. How well these materials for drinking bottles perform in the test and what you should look for when buying a water bottle, we reveal to you in the article.

Pollutant-free water bottles are the better choice not only from an environmental perspective, but also from a health perspective. There is evidence that some plastic and plastic bottles can release endocrine disruptors (endocrine disrupters), harmful plasticizers and phthalates into the liquids. Since a water bottle is used daily, it should be food safe. Food-safe materials are tasteless and odorless and may be safely used to store liquids. When it comes to health and hygiene, stainless steel and glass are virtually unsurpassed because they do not release harmful substances. That’s why renowned retailers like Waterdrop offer only thermal mugs and drinking bottles made of glass and stainless steel. The company is one of the leaders on the market and is particularly popular for its sustainable models. Below, we lend you an overview of the advantages of the environmentally friendly materials that Waterdrop uses to manufacture functional drinking bottles.
