Why you need to drink more – especially isotonic drinks

People who sweat a lot also need to drink a lot to compensate for the loss of water in the body. Sounds logical. But: we all tend to drink too little. Yet a cool drink can refresh us, wake us up, activate the grey cells and – in the best case – it also tastes good. In the very best case, drinking not only quenches your thirst, but also provides you with energy and valuable minerals. This is exactly what isotonic drinks do.

Isotonic drinks: rapid replenishment of water and minerals

Apart from how refreshing a non-alcoholic wheat beer is in every situation – whether in the office, between meals or after sports – its composition efficiently supplies your body with the minerals and fluids it needs. Its valuable ingredients flow directly into your cells and don't stress the body unnecessarily like other, very sugary, fizzy drinks. The difference: non-alcoholic wheat beer is mostly isotonic, but always natural and less sweet because it contains no added sugar. This means that the body has less work to do and you feel refreshed more quickly, because “isotonic” means “rapid” for the body: The composition of the drink has the same chemical composition as human blood and therefore gets where it’s needed very quickly.

Biology refresher: The difference between hypertonic, hypotonic and isotonic

Isotonic means that two liquids have the same concentration of dissolved particles. In our case this means that isotonic drinks have the same concentration of sugar and minerals as blood. Our body cells naturally strive for a balanced concentration. We call the exchange of fluids between cells osmosis. If the osmotic pressure is equal, as it is in isotonic solutions, the fluid exchange takes place more easily.

Isotonic drinks are the fastest way to compensate for fluid and mineral loss.

Drinking enough of the right things in everyday life – so important and so easy

People should drink at least 1.5 litres of water a day. This doesn't take into account sports activities or high temperatures. But many people simply cannot manage this. The result: a lack of concentration, fatigue, headaches. And even those people who do drink more than 1.5 litres of liquid often consume a worryingly large proportion of fizzy drinks, coffee or sugary fruit juices.

Isotonic thirst quenchers are the best alternative when they are natural: no artificial flavourings, no added sugar or artificial sweeteners, no preservatives or stabilizers.

It has been proven that the polyphenols in non-alcoholic wheat beer strengthen the immune system. That means you can quench your thirst with a clear conscience.

Training and drinking

In general, the following applies to both everyday life and sports: You feel better when you drink before you get thirsty. During training, the main aim is to replenish the fluids lost through sweating. It’s best to drink some still mineral water directly before training so that you don't slide into a “fluid deficiency” at the first drop of sweat. Whether or not you should drink during exercise depends on how much you sweat: try drinking about 200 ml of still water every 20 minutes for one hour of sport.

Whether you need water and minerals to be supplied in “rapid mode” depends on how intensively you train. In tough events, still isotonic drinks that supply your body with energy in the form of carbohydrates during physical exertion are best suited. They help you stay fit during the event. They may not increase your performance, but will help you maintain it. In other words: isotonic drinks help you keep going.

Recovering with isotonic drinks

After an intensive sports session you feel exhausted. Sure, because you just gave it your all. The carbohydrate stores are empty, your body may have already tapped into its reserves. Now it's important that it recovers so that you can go all out again in the next session. Replenishing the stores is an important part of your recovery phase. The best is to use the “open window”, a period directly after exercise during which your body can utilise the nutrients and minerals particularly well and quickly. In other words: drink a lot and eat enough after exercise.

Time for some science: a study shows that ERDINGER Alkoholfrei promotes the health of athletes. As a recovery drink after sports, it normalises inflammation levels in the body – which shoot up during physical exertion – and also supports the immune system. An isotonic, non-alcoholic wheat beer is therefore perfect during the open window, when the body is particularly susceptible to infections.

Your muscles are re-energised, your cells are supplied with minerals and water, and you get the refreshment you need – plus a well-earned treat after exercise!

In the case of non-alcoholic wheat beer you can enjoy it not only because you’ve earned it, but because it actively supports your body’s recovery process. You’ll feel refreshed and much better afterwards. And after all, that’s what you’re training for.
