It seems like an eternal discussion: does pure water hydrate better than caffeinated drinks such as coffee and tea? Some health gurus claim that coffee and tea would dry you out and argue for drinking several liters of water a day. But what’s true about this? We investigated!
It is often said that caffeinated drinks would dry you out. However, no evidence for this has yet been found. It is true that by taking caffeine you separate more urine, but this does not outweigh the hydration benefits of the water in the drinks themselves. Another reason why coffee and tea are associated with dehydration is because of the dry mouth you get after drinking it. This is due to the tannins that these drinks contain. And although this substance gives a dry mouth – and with it the feeling of dehydration – no research has yet been found between drinking caffeinated beverages and dehydration. So it is only “a dry mouth.”

But that does not mean that drinking coffee and tea all day long is healthy. A (high) coffee and tea consumption can cause other health problems, such as: stomach upset, heartburn, restlessness, increased anxiety or nervousness, insomnia and an increased heartbeat. In that sense, it is certainly desirable to limit your coffee and tea consumption and to supplement the water intake with water!
Every day you lose around 2.5 liters of fluid, because we sweat, pee, relieve and breathe. The Voedingscentrum therefore recommends drinking 1.5 to 2 liters of water every day. This is enough to – in addition to the water that you get in through your diet – bring your moisture balance back up to the required level. A good moisture balance is important because the water in our body controls many physiological processes. For example, it is necessary for the absorption of nutrients, the removal of waste materials and for controlling body temperature. A shortage of water therefore leads to headache, dizziness and, in the long run, even muscle cramps.
Coffee or tea with sugar contains a lot of calories, just like cappuccino or a latte. Water not at all, but of course also has a flatter taste. Really cold water or sparkling water do give you the feeling that you really drink something, but then something very healthy.
Drinking water is a very sensible alternative if you want to keep your energy level under control. Coffee (and tea with sugar) causes an energy peak, followed by an inevitable trough that makes us inclined to take even more coffee. Water leaves the regulation of your energy level to your body so that you are not completely empty at the end of the day.
Do you want nice and chilled flat and sparkling water for you and your colleagues in the office while you donate 1 million liters of clean drinking water to drinking water projects in developing countries every year?
