Water: That’s why it’s so important for the body!

Would you have thought that an adult consists of 60 to 70 percent water , and our brain even 80 percent? That alcohol and caffeinated beverages such as coffee are not thirst quenchers at all, but dehydrate? Read more about water and how much you should drink every day here.

That is why water is important for our body!

Water is a transparent, clear, tasteless and odorless liquid. It is composed of two hydrogen atoms (H) and one oxygen atom (O). More than half of the human body consists of water. If a person did not drink, they would survive a maximum of seven days.

Water plays an elementary role in our body. It is:

  • thermoregulator
  • Means of transport for blood, urine and sweat
  • Solvent for almost all substances in the cell
  • liquid building block for body cells and fluids

This is what happens when there is a shortage of water!

The water requirement depends on the fluid losses

  • the skin (500 milliliters via sweat)
  • the kidneys (about 1000 to 1500 milliliters via urine)
  • the intestine (about 100 milliliters via stool)
  • the lungs (about 400 milliliters via breath)

The balance is achieved through drinking (1.3 to 1.5 liters), eating (about 700 milliliters) and oxidation water (about 300 milliliters). The latter occurs when fatty acids and glucose are burned.

The most water-rich organs, blood, brain , liver and muscles, are particularly sensitive to water loss. With the loss of one to 1.5 liters of sweat alone – that is around one percent of body weight – physical performance is reduced by up to 20 percent.

On longer car journeys, it is therefore advisable to take a drink break so that you can then concentrate better on the traffic again.

With a water deficiency of one to five percent of body weight, there is a feeling of thirst, malaise, loss of appetite, increased heart activity and body temperature as well as nausea . The heart now has to work harder because the blood has become thicker and tougher.

If this deficiency progresses to up to ten percent of body weight, dizziness, headaches , shortness of breath, inability to walk, tingling in the limbs, failure to produce saliva and difficulty speaking occur.

Above ten percent, serious pathological changes and possibly even death occur. One of the decisive factors here is the speed at which fluid is lost.

How much water should I drink a day?

It is essential that we drink enough every day – preferably water or unsweetened tea. A good guideline is at least 1.5 liters per day. Juice spritzers are also suitable. A water to juice ratio of 3:1 is recommended for them.

How much water is enough per day depends on age and physical activity. Athletes should drink a little more water because of the sweaty additional exercise , seniors are usually less thirsty.

Drinking too little – this is how you find out!

Pinch a small fold of skin on the back of your hand and release. If it stops or disappears only slowly, it’s time to drink.

Once you have mild dehydration of up to five percent of your body weight, you will also have the following symptoms:

  • Durst
  • slightly dry skin and mucous membranes
  • dark yellow urine
  • headache
  • circulatory problems

Which is better: mineral water or tap water?

In principle, both mineral and tap water are suitable for providing the body with enough liquid throughout the day. The advantage of mineral water is that it provides you with additional nutrients. This is especially important for people who do a lot of sport.

However, anyone who eats a balanced and varied diet and does not do any endurance sports is also well served with tap water. The advantage: no lugging of crates is necessary.

Flavored water: how it works!

Bored of the taste of water? Then try it with refreshing and fruity additives such as cucumber, ginger or coconut. The so-called slim water not only tastes delicious, but also gets your metabolism going.
