How can water strengthen our immune system?

Drinking water: A refreshing boost for the immune system

Water is life. You've probably heard this phrase before. It's remarkable how much of our body is made up of water: more than half of our body weight – around 60 percent in adults and around 70 percent in children. So it stands to reason that a lack of water can cause all sorts of problems in the body, including disrupting the immune system. If you don't drink enough, you risk becoming less productive. Fatigue and discomfort, such as headaches, are sometimes the result. On the other hand, this means that drinking enough helps you stay healthy. In addition to the appropriate daily water intake, the quality of this thirst-quencher is also becoming increasingly important. A simple solution for everyday life: a water filter system is a great way to supply yourself with pure, high-quality tap water.

Why drinking water is important

It is easy to understand why we need water when you consider how many substances “float” in the body: nutrients are digested and then transported to the body's cells in liquid blood, either dissolved or bound to transport substances. In the cells, in turn, essential substances are dissolved in the cell sap. The same applies to important messenger substances (e.g., hormones), which also travel via the blood to their target organs, where they can only take effect if they reach the appropriate receptors. The same applies to the immune cells transported via the blood and lymph to their sites of action.

Water is the most natural source of fluid in the body and, at the same time, extremely versatile. Which water is the better solution in each individual case depends on the situation. If we need more minerals, for example after strenuous exercise, we can ‘refuel’ with water (e.g., mineral water). Or, conversely, if we drink pure, relatively low-mineral water from a water filter, it helps us to balance out ‘oversaturated’ tissue and transport waste products from the metabolism out of the body.

Nutritionists and doctors advise against sweet drinks. It is now undisputed that high consumption of sugary lemonades, for example, is linked to high body weight. Unsweetened drinks such as tap water, mineral water, or tea without sugar are much better suited than lemonades, soft drinks, and the like for supporting a healthy metabolism. This is because they do not affect blood sugar levels and do not contain unnecessary calories.

Sometimes it is not so easy to always drink enough. A good trick if you are on the go a lot and don't want to be left high and dry is to take a ZeroWater cup with a built-in filter for your water bottle with you. This allows you to tap water anytime, anywhere, and enjoy pure water without hesitation thanks to the cup.

How water supports the immune system

A healthy immune system can help block pathogens before they spread. But what role does water play in this? The simple answer is that it is a central building block for our health because it is important for almost all life processes. Drinking enough water therefore helps in various ways to keep the body's defenses stable. Specifically, water helps to...

• Keep the mucous membranes moist and clean
• Flush out toxins
• Support digestion and the intestines
• Prevent lifestyle diseases

Keep mucous membranes moist and clean

The mucous membranes of the nose, mouth, throat, and even the eyes dry out when we don't drink enough. This is often the case in fall and winter, for example, when you spend a lot of time in heated rooms. This makes it much easier for colds to take hold. If, on the other hand, we drink regularly and sufficiently, this flushes out pathogens and keeps the mucous membranes in the mouth and eyes clean. That's why it can help to place the table water filter within sight at work. When well filled, the water filter jug reminds you to drink regularly.

Flush out toxins

In a normally active metabolism, a large number of metabolic products that the body no longer needs are produced every day. Sometimes they can even be harmful if they remain in the body. They must be continuously excreted as ‘waste’. This happens naturally, for example, through the kidneys, as well as through the lungs when exhaling and the skin when sweating. Pollutants such as pesticides, drug metabolites, lead, and the like, which we can absorb from food or unfiltered water, also put strain on the body. Waste products are eliminated particularly well when the body's fluid balance is adequately replenished. This means that drinking water regularly helps.

If you are already suffering from a cold or a gastrointestinal infection, drinking regularly is also important and helps you recover more quickly. When the immune system has a lot to do, additional ‘metabolic waste’ is produced. The more you drink now, the better you support your health. Naturopaths believe that water that is as ‘pure’ and uncontaminated as possible has advantages over mineral-rich drinks in this respect. The theory is that it can better absorb unwanted ‘slags’ and transport them out of the body. If you use a ZeroWater drinking water filter for your tap water, you can reduce the TDS (totally dissolved substances) value of your water, including lead and other heavy metals, by over 99.6 percent.

Supporting digestion and the intestines

You may wonder what the intestines and healthy digestion have to do with the immune system. Quite a lot: about 70 percent of our immune system is located in the gut. This means that a healthy gut, including healthy gut flora (colonization with microbes), is an important prerequisite for good immune defense. In addition, the better the digestion of food in the gut, the more thorough the utilization of nutrients and thus the overall supply of important nutrients to the body.

You can support your gut with a balanced diet and adequate daily fluid intake. For example, the fiber in food can only be fully utilized if there is enough water available for it to swell. We recommend drinking eight normal glasses of water from a table water filter every day.

Prevent lifestyle diseases

Many lifestyle diseases, such as high blood pressure, arteriosclerosis, diabetes, autoimmune diseases, intestinal disorders, and more, are associated with poor drinking habits. Protect yourself and support your body and healthy metabolism by drinking enough clean water every day. Uncontaminated, filtered water from a water filter system can make an important contribution to this.

Further tips to support the immune system

Drinking high-quality water alone can have a big impact, but it is not the only way to positively support your immune system. We also recommend:

• Getting enough exercise every day
• Planning enough sleep and rest breaks
• Eating a healthy diet in general

All in all, the immune system benefits from the overall package of a ‘healthy lifestyle’. Important: You should generally drink enough fluids. Include decaffeinated teas in your daily intake, for example. You can even count that cup of coffee. The myth that coffee dehydrates you is incorrect. If you use a water filter for coffee or tea, you kill two birds with one stone: healthy drinking and enjoyment. Sweet drinks, on the other hand, should be avoided.

You should also include plenty of fiber-rich and nutrient-rich vegetables and fruit in your diet. Both provide vitamins and minerals and at the same time support your fluid balance. Get enough exercise every day. But also make sure that your body can regenerate afterwards – ideally with a glass of water from the table water filter. Getting enough sleep helps to keep the body's immune system stable. Right after getting up, you can start your day healthily with a glass of water.
