Water can have a very refreshing effect on us humans. And that’s no wonder, because we consist of around 70% water-containing liquids. Our organs, cells, our brain, everything in our body is dependent on a constant supply of water in order to guarantee smooth functioning. The only thing that is more important than water is air. We need air to gain energy from our metabolism. That means there is no energy without air, but without water there is no long-term life.
But have you ever wondered why water has such a satisfying effect? For example, if you are thirsty and have not had anything to drink for a long time? Or simply when you wake up in the middle of the night and have a glass of water. Is all of this nothing more but a simple trick of our mind to keep us alive, or is there actually a purely physical cause behind it? Some kind of reward system?
I will answer that and a few other questions that you are currently asking here and now.
Have fun while reading!
Water tastes good because dopamine triggers a feeling of happiness in our brain, and hydrogen forms in the water, which gives it a salty taste.
Your Brain and Body has the same Goal
Water sometimes tastes good because it is one of the few situations where your body and brain agree. For example, everyone knows that eating chocolate is bad, but something in our body tells us to do it anyway. However, exactly that, what always tells us that we should eat unhealthy fulfills its purpose this time and tells us that we should consume the water that is essential for survival. The whole thing is called “dopamine”. Dopamine are ‘happiness’ hormones that are released in your brain when you do something supposedly good for yourself. Dopamine is vital because it is one of the wheels that drive us, so to speak. In an expert study, dopamine was blocked in the brain of rats, which then appeared completely depressed and apparently had lost the meaning of life. For this reason, it is important to allocate our dopamine to things that are good for us.
Hydrogen carbonate as a reason for different taste
Hydrogen carbonate also plays a role here. If you wonder what it is, it is a salt that is responsible for the constant pH value in your blood. It has an acid neutralizing effect. Surely you are now wondering what this has to do with water, but that’s easy to explain: Hydrogen carbonate can also form in your water (e.g. overnight) and has a salty taste, which could explain the good taste of the water.
Our Brain rewards us
In addition, it must be mentioned that water is a vital factor in ensuring the proper functioning of your body, your brain, your muscles and your organs. So it should be no wonder that water intake has a satisfying effect on us. Especially after exercise or sleep in which a lot of water is lost through sweating, our body demands water and activates certain chemicals in your body so that this need is satisfied.
Are you getting kind of thirsty right now?
Then it’s no wonder – just the thought of drinking a cool, refreshing glass of water can make us thirsty. – For once, this is a need that you can meet with confidence and without a guilty conscience!
Why does water taste so good when you are thirsty?
Water tastes good when you are thirsty, because it wipes away inhibitors that block your taste buds, the taste of leftovers from the last meal in your mouth is reactivated (like salty chips), or your brain rewards you with dopamine.
If you are thirsty, that is often a bad sign. Namely a sign that you have not drunk enough a day and that your body is already lacking fluids. Water has a rehydrating effect and therefore the opposite of dehydration.
Sweet taste receptors
But there are other biological explanations for this phenomenon.
Water tastes good when you are thirsty, because water washes away inhibitors that block the sweet taste receptors in the mouth and therefore gives it a refreshing taste. Kind of bringing the trash out. Whereby it’s important to know, that everyone perceives it differently, and that others find this taste disgusting.
This shows how everyone’s taste is different from the other – some people are delighted with the sweet and sour taste, while others are more contemptuous.
Remains of consumed
However, if you forgot to brush your teeth, or just by chance, you have leftovers in your mouth from the last meal, this might have an affect too. If you pour water on your leftovers, the taste of the food will be “reactivated” again. It is also of course clear that the “before and after effect” plays a significant role here. That’s because if your mouth is dry for 8 hours while you have been sleeping peacefully and then suddenly water comes in, it simply has a refreshing effect on your psyche and reactivates your spirit.
Why does water taste better at night?
Water tastes better at night because water can become stale overnight, the tip of your tongue reactivates with fluids that allow you to taste sweet things, or your toothpaste – taste fis too strong.
Stale water taste at night
Depending on where you live, the water you drink can play a big role. For example, if you only drink tap water and fill it into your bottle, it is quite possible that the bottle with water will be stale after a while and has a sometimes good, refreshing, but also often disgusting taste. For this reason, it is best not to take plastic bottles, as it is much more likely that the water will be warmed up during the day and take on a different taste, but rather in a closed thermos, where you can calmly drink from it.
Tap water, does it matter where it comes from?
The taste of your tap water itself can also vary greatly from day to day. It all depends on where you live. In some areas, water tastes significantly more iron-rich or sweeter than in others. If you have ever been on an expedition to a waterworks and have paid attention to how exactly the water is made drinkable, you also know that the geological stone layer below the water, which determines which minerals are present in the water, has a great influence on the taste of water can have.
Toothpaste and it’s effect on your taste buds
A very plausible reason could also be leftovers from your last tooth brushing process on the day before the last. Water ensures that the flavors in your toothpaste are reactivated – even when it is actually undesirable. Imagine drinking a large glass of orange after brushing your teeth. – It’s disgusting, isn’t it? Yes, simple, otherwise relatively tasteless water can have a similar effect if it hits your dry mouth.
Your toothpaste may also be a little too flavorful and you should switch to a different one that has a more neutral taste.
A dry mouth, a serious problem?
The tip of your tongue may have dried up during the night. The tip of your tongue is very sensitive and is mainly responsible for the fact that you can taste sweet things. So you can surely imagine that if the tip of your tongue dries up due to your dry mouth, that can give a very strange taste when you put it back into contact with liquid.
The End of the Line
In conclusion, it can be said that water itself simply has a relaxing, calming effect on us, and our body therefore rewards us with a satisfying effect. And yes, even if things like dopamine or other physical causes play a role, we shouldn’t worry too much about it, and just one thing: Drink a refreshing cold glass of water and enjoy it!
